Did the cam belt break? If it did, you need to pull the head off.pappytree said:
There is a cam lock bar that goes in the rear of the cam when the sprocket that drives the injection pump is removed, then a TDC mark on the flywheel that you see through a little window in the bellhousing.
Cam sprocket in front gets removed and sets loosely on the cam during belt tension. It must be allowed to rotate while the timing belt gets tensioned.
Once the cam timing belt has been set, and the sprocket on the front tightened down, then you install the pump belt by loosening the bracket-to-block bolts and letting the whole assembly slide UP or DOWN to tension the belt, then set the timing via dial indicator same as you do on the 4 cyl VAG IDI diesels.
no break
Ok, the belt did not break, I bought the car from a guy who said he put a pump on it and wont start, got it home, tore into it, and realized no way to set the cam, I will take that back gear off tonight. I assume im loosing the compression on belt install as I had the front loabs pointign equally up. Do not have the tool but can surely fashions something. Anything else I might need to know?

You may want to buy a manual. The Audi 5000 5 cyl diesel is essentially the same engine minus one cylinder, too, if you can find one of those manuals second hand.
The rear cam lock bar is the same for the IDI 4 cylinders as well as the early TDIs, and are available pretty cheap. The dial indicators are not that expensive either, but you can usually time them 'by the seat of your pants' and get them pretty good.

great
I never had to use the cam lock on my priors, how is it orienting the cam? what is it locking into? Could you direct me to a photo of it as well as describe how its locking the cam? I found a notch on the back wheel that I thought was for timing but it really didnt make any sense how that could be as it went no where and it appeared to be a cone fit wheel.

You've never done a VAG diesel timing belt correctly then. You really need to get a manual. And the proper tools.
