it sounds to me like the car just needs a good old fashioned italian tune up :lol:

ok here's the video.
you can hear the idle bouncing and missing for a few moments and then straightens out.
you can also see the smoke that i'm blowing out.
i still think its just the bad fuel.

From what I can hear it sounds a little noisy. Almost a metal to metal sound, but it could just be the camera. The smoke to me looks like a little unburnt fuel and the rough idle with the sound makes me think the pump may still be off. Or the glowplugs are bad and the fuel is bad.
I would recheck the pump, cam, and crank timing. If that looks good run a couple of tanks of fuel through it. Also, you could check the spray of the injectors.
That wasn't you in the car was it? :lol: I figured you looked WAY different LOL.

Im way way late on this thread, but that video was me a month ago. Loud engine, erratic idle and very long cranking time. I know it cost a lot, but it solved my problem. I had the pump rebuilt.

the engine timing is perfect.
the pump timing is perfect.
they did just put all new lines in it this morning.
so i dont think it's fully bled which is why it took a while to start.
injectors were all tested on the injection machine, they were all perfect.
PS: the exhaust is hitting under the car also!
thank you all though, as i said before i'm gonna try new fuel with power service in it, and new filters, and just drive drive drive and see how it goes.
the car does start right up everytime after once it's warm.
in that video i want to say it was only about 35 degrees out too.
and kevin just admitted to me that he hasn't been glowing it before starting! :shock:

oh! and supposidly my cold start doesnt work either according to the diesel tech.

Did you confirm that the timing mark on the flywheel corresponds to ACTUAL TDC?
i would definitely get this checked... and the rough starting is probably the pump sucking in air from changing the lines. if it starts like that everytime then you have an air leak, or some bad glow plugs. even with bad compression and good glow plugs, it will start wayyy quicker than that.
now if the timing is actually okay, and the valves aren't hitting the pistons, then maybe the valves need to be adjusted??? i've heard enough mech lifter engines to know that yours does sound like something is wrong, unless its the camera amplifying the noise.
one time i let my 1.6TD drive with low rpms (really lugging the engine :oops:) - enough that the oil pressure was probably really low. soon after i noticed a bad clack sort of like what you're experiencing. i checked my oil and it was indeed low so i topped it off, and then after some revving and spirited :twisted: driving, the noise went away and never came back. oh the joys of hydraulic lifter sticking :lol: one of the benefits of mech lifters- they don't stick!
sometimes stuck injectors can sound like that too... but i wonder if a bad delivery valve or pump could produce the same effect? hmmm
once everything is confirmed and you have an oil pressure gauge (and enough oil in the pan :lol:) confirm you're in the green with regards to that, then you might just need to do the ol' italiano tuneup.
ps watching that video again... the way it sounds when you turn it off... it shouldn't clack like that without fuel. (thats not diesel pinging-so not injection pump or injectors) remove an injector and use a metal anything-that-will-fit-through-that-hole-into-the-cylinder to absolutely confirm that the flywheel has the right TDC. there is also a slight chance that it is the mech valves that need adjusting, but i dunno. they could be a little too tight maybe.

once again than you all for your advice and opinions.
however, i don't think i'm getting anywhere here.
i know what valves hitting pistons would sound like.
i maybe a girl, but i know what top dead center looks like.
we know for a fact that oil pressure, injectors, and the pump timing is all correct and perfect. i'm not new to cars. i'm new to diesels.
i either need a new pump or new fuel.
that clanging you here is the exhaust because it only has one hanger at the moment.
thank you again though.

I just read the whole thread. You have done a lot of good work. I also peeped over to the Vortex thread you have. Give this poor little bunny the new Injection Pump she deserves. :wink: It been working hard for over 20 something years. ( I dont know your year, looks like an 84?)

yes she's an 84
i dont remeber if i gave yo guys the back story on this car but it was found in a barn by my friend chris (the son of the owner of the dealership - seen in the picture towing the rab). i guess it was this old guys car and when he died his wife stuck it in the barn for years and years. then chris found it and bought it for 400 bucks. sold it to our other friend adam for 1400 who drove it back and fourth from taunton to providence for work for like 6 months until he blew the car up. it sat in his yard for a year and then i bought it for 1300.
i was hoping that the pump stayed in good condition but i think i just might have to send it out for a rebuild!

Send it Up to GILES to have it Rebuilt and SUPERPUMPED!

It sounds like the idle is too low to me, or the timing is retarded.
I haven't read your entire thread so I apologize if this has been covered, but what is the pump timing set at?
How did the diesel tech confirm that your cold start lever is not working?
I couldn't see your pump close enough in the video but being a 84 I doubt it has a fast idle; which makes it pretty hard to determine if the cold start is doing anything or not. If the cable is hooked up and the lever on the back of the pump is moving then the cold start is working. Either that or the advance piston is seized, which does happen on very, very rare occasions.
In the video, the engine was cold right? When it's warm, does it idle or run any different? Have you checked the valve clearance?
Do you have any fuel leaks at the injectors or pump? It could only be running on 3 cylinders. How violently is the engine rocking when it is at the lowest RPM it can sustain?
Get your boyfriend to hold the RPM as low as he can and crack open the injection lines one at a time. If there is no change in RPM then you have a bad injector. Just because they were good on the test stand, doesn't mean they are still good. Injectors are the most finicky thing. The smallest spec of dirt or rust can cause them to stick.

I was hoping that it was something other than valve contact. If the pump had been previously untouched I would send it off to Giles as I stated earlier. That is if the driving it for several hundred miles with the ATF and diesel purge don't help. Like I said earlier it sounded noisy, but I didn't want to say that I knew what it was for sure. It really didn't have a sound that I recognized for sure and I am so glad that you said it was exhaust hitting the car. That is fixed with a couple rubber hangers or coat hangers and mechanics wire
