Hello everyone, have been consuming for some time now, and really feel that this is a super knowledgeable community when it comes to these vw diesels, which is great because I have found me one, finally.
I have picked up a 91 EcoDiesel and will be leaning on you all to help me along. If that is ok, of course.
So I pull in to the circle K for my morning coffee and pull right up next to it. My heart jumps up in my throat as I see the badge. I have been looking for one of these cars for some time and either the money wasnt right, or the car wasn't
I take a quick look once aorund it and then go inside, I ask out loud who owns the Jetta, and this older fellow answers. I tell him half jokingly Ill give you 1000 bucks for it right now.
He responds, "How will I get to work?" After a quick laugh we proceed to talk about the car. He is totally in to the idea of selling it. The car is in stellar shape. Not a spot of rust anywhere, the interior is immaculate, and the engine compartment looks decent.
Everything works, recently upgraded aircon, and some other necessary redos like linkage bushings and radiator flush has been completed in the last two years.
We agreed to meet up today so I could take it for a spin.
Has a little rattle that the guy thinks is the water pump. After a little inspection half way through the test drive, me and a friend I brought along, discovered it was the radiator fan shroud rattling, its a little bent. But I'll take the free water pump he is including. Also including the steel wheels for this car.
Took it out on the interstate and run her up to 70. She has a little wobble in the wheel which feels like a wheel balance issue. She tracks straight, but surprisingly it didn't feel like it was going to fly apart at speed.
She definitely needs a servicing . I think the paint work will brighten up well enough and I might go with a black hood. As you can see the interior is in great shape as is the body. I couldnt find a spot of rust and the wheels look really good for their age, they should refurbish easily enough.
The hood is the nastiest bit on the car, but am thinking of just sanding it down and shooting it black or maybe primer, for now. I cant decide between E types or quadrounds, only cause I want the halo lights.
There is a l bit of oil grime on the motor, and we picked up 1 drip of oil after running the car at speed and then letting it sit off in the parking lot. Its gonna need some gaskets, its got 191,000 miles on it. I gave him a deposit as so he doesn't sell it, took the title, a bill of sale, and the Bentley Manual for it home. I will pick it up this weekend.
I was thinking bigger turbo to get more out of it in the beginning , but as I have been reading, I am thinking its not the way to go. From what I understand, this Giles makes legendary pumps, and that seems to be where the main gain can be had. Cat is already gone, and I see 2.5 is the way to go.
First on the list though is a complete first echelon maintenance. Belts, oil, engine bay cleaning, brakes, gaskets, radiator flush, fluids, and thorough cleaning.
But I had to show you all this engine bay. I cant help but to laugh at that red wire that is looped around the cap of that reservoir. Please feel free to enlighten this diesel noob on the insanity of this bay. Im new to diesel, but am a wrencher.
Here ya go:

Wow, if you picked up that car for $1000 you did good. Rust-free is definitely the way to go, so you're already one step ahead. That engine bay looks very good for 190K miles.
Yes, as far as performance, you would benifit most from a pump upgrade. You need a turbo pump with boost enrichment device and larger internal plunger. As mentioned, a Giles super-pump would be even better, but a turbo pump would still help a lot. A 2.5" exhaust will also help, as would an intercooler.
-
Sweat find !! Are you north or south of the boarder ?
The wobble is likely a bent steel belt in a tire caused by a pot hole. Lift the car, spin a wheel and watch the tread. It that's it, you'll notice at some point the tread moves to one side a bit. The tire would be trash, but its an easy fix.
Yeah, Giles pump, no cat, new 2.5" exhaust from the turbo down... ENJOY !!
ps - follow the bently to the letter on swapping the timing belt.

Looks like "Location: Aplha Quadrant" translates to be somewhere in Florida from the bits of the plate not fully expunged. Why don't you be a little more forthcoming on your location, DieselBalz? We're not likely to kill you...I have the spittin' image of that car in a '91 NA Jetta, including the burned up paint. I wish my dashboard cover looked like yours- are you sure that's a Florida car?

Nice find.
It looks as though the heater core is bypassed. That might not be a big problem in Florida. ;D
Good luck with it.

Nice tidy project.
On a bang for buck philosophy I wouldn't say a pump was the best option - probably one of the last.
You can get another 70-80% more power for less than $100 if you look to the more obvious mods first.
boost controller
boost gauge
intercooler
egt gauge
few pump tweaks
Then maybe go for the 'superpump'
Mind you, I have noticed you've got the awful pump, that is thankfully pretty rare in the UK.
-
Yess, where exactly is this located hissss? ;D Nice find.
First off,...
new steering wheel.
I hate that wheel, huge area you can't wrap your hand around,.. recommend the 4-button.
-
Located in Tampa, Fl. Indeed I am gettin it for a grand. I am super excited about getting this lil diesel performing well enough to be my daily commuter.
I also look forward to buffing the remaining good paint on the car and blackening the trim up.
I will look through these forums and seek these upgrades you speak of. I am definitely a gauge kind of person as it helps diagnosing issues ahead of time. Planned is a voltemeter, tach, boost, oil temp and EGT.
I will post any progress with pics as I go along. I only plan on slight modifications as I do love the mk2 styling. Lowering it is definitely on the list but first its gonna be the mechanical improvements, and once that is solid, I will start improving her appearence.
Still can't decide on e types or quadrounds. The halo lights are so sick, but th e types are soooo clean!

I really like my mechanical temp gauge too.... before it I over heated twice melting the HG !!
-

Not only does it not have any boost fuel enrichment, but it's also internally sporting an 8mm plunger instead of the typical 9mm.
Now is that something (the plunger) I can upgrade if I dismantle the pump and rebuild it? And I haven't been able to figure out whether or not I can add the LDA to this pump? It appears to be what giles does, but am unsure if its a simple bolt on or if it takes machining.

I am not a big fan of it either. But I want to keep the interior as VW as possible. I will cruise some searched pictures of VW steering wheels, and try to figure out one I like. Hopefully snag it from a junk yard.

I am pretty sure it didn't start its life down here. It has a dealer sticker on it from Wilmington, DE. I am gonna do a carfax on it just to get a little history on the old girl. I'll post my findings.
-
Adding the LDA has been discussed before. Search is your friend. Basically there is a pin that needs to be removed and the hole plugged. After that, the LDA is a bolt-on. Yes, the plunger head can be swapped, but you'll have an easier time if you just get a working TD pump.
I will search both adding the LDA and getting a working TD. I need to do something because she is flat out at 70 mph. Thats all shes got, and down here on these FL roads, you need some more speed to defend yourself on the interstate.
I have a commute that is almost all interstate, and will not make it my daily commuter until I can get some more out of it.
Off to the Search box....

RED WIRE! RED WIRE! Securety to Engine Bay!!!
Looks to me, Captain, Someone has run a new wire to the fuel shutoff valve.
Yes, I think you might be correct Mr Speckless! (Turns head aside and whispers "TURN OFF THAT ALARM, PLEASE!)
-
i too had to run a new wire to my fuel cutoff, as i shorted it out while messin with the fuel screw with the key on listening to tunes.... ;) I just spliced in a new lead under the dash instead of running a whole new wire though.. The blue w/black wire coming from the 4-way switch is HOT in Run and Start.

Update:
Finally got it home. Drove it home on its own power, no issues. Took a little video of the vehicle walk around. In it I pose some questions to all of you about various things with the car. Please feel free to comment or offer suggestions on the best way to go about some of these things.
Happy viewing!

I agree. If you don't know how many months and miles ago the timing belt was changed... then handle this first! If your timing belt breaks your head will be toast, or worse... This engine has an interference head.
You are lucky to have gotten an ecodiesel because the previous owner(s) obviously could not abuse the engine.
The transmission on 91-92 jettas is suboptimal for freeway travel over long distances. A taller 5th gear would be quieter, more comfortable, and lower rpm's.
I am concerned that you say you cannot top 70 mph on the freeway. This should not be the case on flat surface without a head wind. This IP will take it's sweet time getting you up to speed, but you should be able to push up to 80 mph at least. This makes me suspect the timing and/or injectors. I would refresh the injectors when the new IP goes in. The timing will get handled when the IP goes in. Giles rebuilds injectors too... If you want power over economy then look at GTD injector nozzles.
It would be most time efficient in total to do the IP, injectors, and timing belt/pulley all at once.
I agree that the Giles pump is worth the effort. That is my experience.
There is nothing wrong with the K14 Turbo (though it would be a good idea to check for shaft play if it is original with 191K). Many people prefer it for around town use. This Turbo gives nice power at lower revs. A larger Turbo from a 1.6 TD would give you more oomph at higher rpm's. The consideration is that these don't spool up until your revs get up there... which means you won't be racing anyone around dead man's curve. LOL.
Nice find. Congratulations.

you would benefit more from swapping to a na pump than from simply adding an lda

Thanks and thanks as well for the other responses. I tried it out again making sure tires were at correct pressure, and I was able to just get over 70. I am going to do the Diesel Purge and see if that doesnt help some.
Although the car is in overall great shape, I am discovering bit by bit little things about it. Like how one of the previous owners has used a wood screw to fasten the trim to one of the door panels, as well the grill.
I plan on doing a full service though, belts, hoses, and the usual stuff like oil and fluid flushes. Brakes, air cleaner (upgrade to the K&N insert for now) Ive cleaned the exterior and attempted brightening the paint. Wheels came out great and the interior is on the list as well.
Its nice to have a project.

Finally got around to the carfax. This little gray goose has lived most of its like in the south. Probably why there isnt a lick of rust on her.
She appears to have been in a few fender benders. Although the rebuilt titles confuse me a bit. It seems like its linked to major vehicle damage, but I cant see any damage on the car, or evidence of major repairs, that would indicate a totaling of it. Its one of the first things I look for when I buy a car. Maybe some of you can shed some light on these kinds of titles.

Based on the excellent advice you can find around here, I have just finished up my first LM diesel purge. I used the excellent how-to from the post on the TDI Club forums as the template. I went and purchased the required supplies, and put it all together.
The EcoDiesel is older then the car in the pics from the thread, but I am pretty sure I was able to figure out which one was the return line. I am also pretty sure because the Eco can now get up to 75 steady, in contrast to the 70 mph top speed reported earlier in this thread. Also, she seems to have a little more umph, and lastly, the yellow light with the double loop emblem (don't know what its for) didn't come on at all on the test drive after.
Just in case though, I have posted a few short vids for your consumption. The first vid is there to have the community confirm I did it right, and the second video is there for you all to take a listen to the engine at various speeds and comment on its health.
http://www.youtube.com/watch?v=UJsk60fHvQE
http://www.youtube.com/watch?v=jCszQ-Pt3Cw
The whole process took about 30 minutes and I feel it was worth it! (If I did it right!)
-
Looks like you got this thing under control, and from the two video's you do it professionally ;)
The yellow light in the dash with the two loops is for the glow plugs, not sure whats up there.. if the car still starts fine, and the light does not come on after starting, i wouldn't worry about it. Odd however that doing a purge stopped the light from malfunctioning? You must have knocked something back in to place or something. lol
The engine sounds very smooth and the turbo sounds peppy. But from a video we can't really tell you anything about its health unfortunately. If the engine only has 190k (miles I'm assuming) then its still a baby lol and has a long way to go. to put it in retrospect. My own little 1.6 N/a is coming up on 600k (yes miles)... still runs its little heart out every time i drive it, she pulls her own on the highway too.. 34-3500 rpm and 85 mph cruising no problem with four people in the car.
Your well on your way to a very successful little car here buddy :) Keep up the good work.

Back with an update. I have installed a new cone filter to replace the factory air box. It does seem like she has a little more pep, and over all I am pleased with the outcome. It has caused me some questions though. When I took out the air box I noticed this little circular attachment to it that looked like a vacuum hose should be attached to it, (there wasnt a hose connected though.
Is this something I should worry about? Or is it something that is just massed produced and that vacuum module is used in another vehicle application?
Another thing I noticed was that the airbox had another tube below the air filter that had a flap sort of covering the inlet. Is this something I should worry about not having with the cone filter.
I attached the filter to the factory hose that the airbox connected to. Please feel free to lay upon me the error of my ways if I have committed some.
Lastly, I tackled the hood. If you look back at the first page threads, you can see that the hood was quite nasty. I have spent most of Memorial Day Weekend on this project. I have posted some videos of my progress.

All nooks and crannys down to the metal! Ive since acetoned the bejesus out of it, tack clothed and remasked. Have just put the first coat of primer down and am preparing for my first round of wetsanding.

Just posting the finished product.
All shaker can. Satin Black after a few coats of primer, wetsanding, and lots of learning.

Thanks! Not bad for my first time refinishing a hood. Many tips from this site helped me with the process!

Hood looks great. I would love to do that on mine, but the roof and deck lid are just as bad. I think I have some charcoal grey that may be close enough to work on mine to do all the top surfaces. This color is idiotic in Florida...

Although I am pleased with the results, I probably will not do it again unless I have the correct tools. The shaker can method was difficult and caused me extra work and grief a couple of times. Ultimately I would like it done professionally.
With the surface area that you need to have covered, I would recommend a professional respray. But you can save a ton of cash by doing the prep work yourself. Get a good orbital da sander (read: not a Ryobi, took me forever!)
Thanks for the compliment though!
-
its all a learning curve for first timing something, and cheaping out on tools as you learnt is not always the best of methods.
-
Man this thread is old, but instead of starting another I figure I would just keep this car's progress in this thread. Kind alike a build thread, except I wont be tearing any motors down. (at lest not yet)
Lots of little things have been repaired or replaced. Timing belt, water pump, power steering pump & reservoir, new v belts, fuel filter, oil change.
The fuel return lines were rotted out and one sprung a leak while it was warming up at my local Circle K whist getting coffee. Two learned lessons from that. NAPA is the only real auto parts store here in Florida. Everyone else are just accessories and cleaning supplies stores. Window washer fluid tubing is not a good replacement.
Now for some pics. If ya like you can go to page 1 of this and see the "before".
Upon recommendation from just about every user on this site, I have got some gauges installed. I have one or two left to go, tach and volt. I liked the VDO gauges and went with the BFI Kit. Although I felt like an *** once I got the kit and realized what I paid 25 dollars for. None the less..

Other than that I have just rubbed on it some to brighten it up, clean up the plastics, and tinted it. (A must in the "sunshine state")
Just plan on putting eibachs all around to drop it a bit, those sexy black nickel wheel studs from BFI, e codes and smoke out the rest of the lights, and an intercooler. I've snagged one from a junked Saab 900S. That will be about all I will be able to get away with before my fiance pulls the cord on my VW spending in anticipation of the upcoming wedding in Feb.
Here is what she looks like currently...

Have you replaced/altered the injector pump for a turbo one with LDA top? Just curious what does it go like compaired with other cars? question being what other cars too (vw?)
Whats your MPG been like?

I still have the eco pump on it and have only been driving iit regularly here in the past month or two. Even after dumping a quarter tank of fuel all over the ground on two separate occasions I got 300 miles on ten gallons. This tank will be my first full run hopefully now that I have proper fuel return lines on.

I've had a few eco diesels. That looks like a nice one. Here's what I'd do to it if it were mine. I'd get a transmission from an 85 to 89 Golf or jetta diesel, get a true turbo pump (just happen to have one here if you're interested), and put the stock air cleaner back on with a Mann filter. You don't want a cone filter down there in Florida it will just suck that fine sand right thru it. The stock air filter box on that is bigger than all the other diesel engines so use it, it works good. The k14 turbo those cars come with is great too, don't change it. Don't overboost it and don't over rev it you'll just ruin it if you do ( and it's easy to over rev with the AVX transmission those cars come with).
