hello i just joined this forum, and wanted to share my resto on my 1983 4 door rabbit diesel i just bought.
plans are to keep the keep engine stock for gas mileage, other plans are to fix all rust and then slam it 8) but not to low, i live in PA we have (profanity removed by moderator) roads. Most of my time will be spent inside the car the interior was wrecked, carpet is shot. hopefully the floorboards are in good shape(looked good underneath) I havent heard it run yet ethier, but it does turn over freely, its been sitting in a yard since 03.


stuff i need to get
1) rebuild injection pump i got a leak around the input shaft.
2) raceland coils
3) carpet
4) buy a mig welder 8)

good news got her runing today, bad thing is that the injection pump is leaking behind the timing gear, I assume that its pulling in air, because it wont idle. looks like ill be replacing some seals on the injection pump

Probably the shaft seal on the IP. It can be changed with the pump in the car, lot easier with it out. Pull the sprocket off, get the seal and replace it. Good as new. Mine was weeping on my 84 years and years ago, replaced it and never had an issue.

Got all the interior out, carpet seats... etc, I was really happy to see the floor panels are in great shape, i was expecting to see rust holes everywhere.
Image
Tore up all the sound dead material on the floor.
Image
Image
started to wire wheel the floor.

got kinda side tracked with replacing the door, some one shot the old one with a rife or something, It put a big hole in it :cry: and broke the glass, lucky my friend has a replacement, almost the right color.

could this be why its hard to start? i noticed after i leave it sit, all the fuel is almost gone out the lines.

Yes. If the seals leak the IP won't hold fuel. The incoming air allows the fuel to siphon out of the pump. It will also cause driveability issues and rough running. The IP is a two stage pump, low pressure supply and high pressure distribution. When air leaks, it sucks air which causes all kinds of problems.

Air in the line will make it hard to start. The diesel leaking on the belt and hoses will eventually soften the rubber. If it's leaking quite a bit the best route is to get a seal kit from a Bosh service center and install it.

Be warned the main shaft seal usually does not come in the seal kit. It usually has to be ordered separately.
