You do know that this is a very old thread discussing GAS VEHICLE EGR SYSTEMS and that not much mention was made about diesels until the last few recent posts. The EGR may not be good for the...

I think it's time to pull the heads and have a look see. Once you get them off, turn them so the combustion chambers up facing up and level so you can fill them (combustion chambers) COMPLETELY with...

If you're lucky and just the cam timing off, you should be able to verify compression and maybe not have to remove the heads. Re-verify the torque on them though. I've never tried this but, I think...

You do know that if the valve timing is off the compression pressures will all be whacky too.....valves opening/closing at the wrong time? Since you probably couldn't do a compression check before...

Doing it that way is by far the easiest and safest way of doing the front end, especially if you don't have the correct tools and time. I did mine quite a few years ago and won't ever do it again....
