Haven't posted in a bit but I finally found the source of my issues.
Some of you may remember that I have been having vibrations through the rev range. Changed a bunch of things.
Timing chains, vanos, sprockets even the oil pump.
After all this the problem was still there and seemed to be a bit worse than it was a few thousand miles ago. Early last week I decided to do a bit more investigation after being very pissed about the problem still rearing it's ugly head.
Traced the noise to Cyl #6 by doing a plug cut the noise went away. did a compression/ leakdown. 205, 206, 209, 205, 207, 195. Leakdown test was good on all of the cyls. Pulled the pan to check the rod bearings.
As you can see the upper shell looks like a bent con rod while the lower shell does not. I'll just change out the bearings hmmmmm...
A couple of days later I take a good look at thing to see if there are issues.
YEP!! Bent Connecting Rod!!! Only way to bend one and still have a motor that works is hydrolock. The off this car had was in a water filled ditch.
