IDI Engine / Re: Timing belts
« on: August 18, 2015, 06:17:11 pm »
I have had nothing but good news out of Conti belts for 20 years, but the last one I put on was 4 years ago.  I am about to spin up a Mitsuboshi on my 1.6 rebuild.  Don't know how it will work but seems to be a lot stiffer that Conti.  They are an OEM to a lot of Jap cars.

I don't know that particular alternator, but frequently Rock Auto has the dimensions listed in the descriptions.

The only way it would ruin my engine would be if it grenades and takes me with it.  My head will be over it.  I have the right filter, just want to use this one up, if I can do it safely.

Yes, seems to me they all use the same oil pump. I am using the gasser filter flange (this is a cabriolet conversion) as it has the car pressure and oil temp sensors. I need to double check the seat before I make a mess.

...just once. Does it blow up? I just have one leftover mahle oc47 that I want to start a rebuilt engine on and run for 20 minutes before I change it and the oil. Looking in it, there looks to be a restrictive valve an inch down. I dunno....

I put Grant rings on them.  I have them on my Jetta and haven't burned much of anything on it in 80k miles, with less than perfect bores on it.  Fingers crossed on this cabby.

CR is the engine code, as in  one of those old creaky 11mm blocks.  Yes I know about the current best practice to buy studs, but I started this business 21 years ago before anyone knew better (Al Gore hadn't invented the internet, can you imagine life before forums like this?).  I haven't ruined a block yet, and I have already torqued the head to final value with no obvious ill effects.  Do I feel lucky?  Youbecha..

'94 is when I bought this block (probably manufactured around 1981) as an assembled shortblock.  Evidently the MOFOCO morons didn't center the thrust bearing as it eventually ate up its crank.  I rediscovered it and thought I would put it to use.  (Actually, billybobf, it contains the O/S pistons you sold me via theman53 about three years ago...when you retire eventually projects find a way to get moving)

IDI Engine / Re: Glow Plug Shape
« on: July 26, 2015, 06:14:34 pm »
VW used both blunt and pointy glow plugs.  You may find the more blunt ones are slow-glow.  If memory serves, the mercedes ones are longer and won't fit. 

that seems to be the case.  All the blunt ended ones I tried as the fourth plug took more than ten seconds to get hot vs the other 3 when viewed through the open injector holes.  I tried a Beru, Champ, Monark, and a blunt Bosch and all were slow...

Diesel Swaps / 1.6 CR IDI into 81 Rabbit Convertible (Cabriolet)

This "project" has been ongoing for almost 10 years now.  First I was going to just get the original EN engine going.  Then I was going to pull and rebuild it.  Then I was going to swap in JH (actually did).

But I'm a dieselhead at heart so eventually realized I had enough old CR parts to convert.  I had a CR shortblock that I had bought from MOFOCO in '94 that only did like 30k miles before the center bearing trashed the crank. So, I repistoned that and got another crank and I am about to light that puppy off in the car in the next few days.  But I am going to just run it off the battery and a small fuel can, without going through the car wiring or gas tank.

Question is , when I eventually get it running on the proper wiring, I know I need to bypass the fuel pump wiring somehow so the the ignition will engage the starter.  Anyone know how?

IDI Engine / Glow Plug Shape
« on: July 26, 2015, 03:14:18 pm »
Hi guys.  I am re-engining an '81 Cabriolet trying to use up parts I have squirreled away from 20+ years of working on VW and MB diesels.

I have a small pile of glow plugs, but only 3 that have a similar sort of "pointy/tapered" shape - I think the pn was 0250201032  which I think is really correct.  The rest seem to have a more blunt end -perhaps these are MB?

IIRC, the injector is aimed at the glow plug on a VW, whereas the MB has an internal ball for this purpose. 

Is there any real issue with using a "blunt end" GP on a VW?  Just trying to use up all my stash.....

IDI Engine / Re: belt tension
« on: September 16, 2014, 08:56:09 am »
Now you have me scared.   I am sure my belt is on the loose side , as it "flops" a bit.  OTOH, I have been running these cars for 20 years now and never skipped a tooth or wore out an intermediate shaft bearing or pump prematurely.

After re-reading the passage in the manual above I see it reads "between the injection pump sprocket and the CRANKSHAFT sprocket"...can you even twist it there?  (that can't be right...the picture shows pump to cam sprocket)

They certainly were German and good  at one time, but like everything else these days it's a crapshoot.  Sometimes even when you have the hardware in your hands you really can't be sure.  I know...I'm not helping any...

« on: March 25, 2014, 01:29:06 pm »
When you get 500-600 per tank and all the power you need and a dependable rig, distance doesn't matter.

maybe when you are young...

I have a 64 mile round trip commute that takes 50 minutes on average, taking mostly 2 lane roads and a bit of city traffic.  I have been doing that for 16 years , mostly in my Rabbit P/U or Jetta , sometimes in my 240D stick when I felt like wasting fuel.

Four years before that I was doing an 80 mile r/t in my pickup.

I've had enough of work...retiring later this year.

If my daughter is lucky, she will get into a better high school across the county...and I will have a few more years of commuting. I think that is a 40 mile r/t, but twice a day.  Might get some help from SWMBO or do some car pooling with other kids.

Troubleshooting / Re: Intermittent Stalling
« on: February 13, 2014, 07:27:41 am »
I have replaced the MkII filter with a MKI- screw-on.  I have a clear Mercedes pre-filter in front of it to see what my fuel looks like.  About a year ago I had a leaking return line (leak was a couple of feet behind the filter where the line goes into the chassis) so I had a lot of water, but that has since been fixed and there no significant water now.

No issues in the last 2 days, since I got away from the B20.  But, it was a very random occurrence anyway.

Troubleshooting / Intermittent Stalling
« on: February 11, 2014, 10:31:28 am »
A couple of times a month , when the car is cold ( well, chilly- this is Florida), I will start the Jetta , drive about 5 minutes down the road at moderate speed (35 mph in 4th) and the car will sputter and die.  It will restart, then go another 2 minutes and try to die again.  After that, no problems.

I changed the filter and checked the "out" bolt.  Any other ideas?  I had been running Murphy Oil B20, but today I filled up with the real stuff just to see if that matters.
