Rod bearings

[hillfolk'r]

the reason the overlay is lifting is usually caused by glycol contamination
it attacks the bearing material+causes that exact problem
it may not have been you that did it ,it coulda been 10 years ago,maybe it blew a head gasket,or oil cooler once in its lifetime

as far as the pedal vibes?
get one of the counterweights that bolts on the clutch release lever
i swapped trannies  in my car+had vibes like that
i installed the weight from the old trans,and its alot better now...
are you runnin hd trans mounts or have a broken mount??? thatll do it too
its not broken straps
if you broke straps the clutch wouldnt release,ask me how i know
 (drove it 10 miles home with broken straps)

had to drive a week on only one strap then it finnally let go. I was baffled i had no idea that, that was the problem. I was dam SHOCKED :shock: I am also having a vibration in the clutch pedle of the passat (aaz) but its hydraulic clutch....

i had vibrations on an audi 5000 with a hydraulic clutch... one cold day the vibrations got worse and worse... and eventually it wouldn't release the clutch.  had to start the car in gear and drive it home... downhill it would start in second to make it easier  :lol: at that point the clutch pedal would move to the floor no problem.  once it sat in the driveway for a couple of days the clutch pedal was stiff solid.  thought it was the clutch master cylinder, but got rid of the car before i ever found out.  hopefully it was something much worse than a master cylinder... even a slave cylinder wouldn't have been too bad for that motor... it was real solid!  the galvanized body had paint bubbling/flaking but NO rust!!!!  damn i love audi's!!

i would highly recommend getting your hydraulic clutch system cleaned/flushed if it has never been done before. the fluid that came out of that audi was absolutely disgusting!!!! i think the hose started to degrade and ruined the system.

On the 1.9TD and TDI the rod bolts are "stretch" bolts and must be replaced. I'm not sure about the 1.6D/TD.

As far as I know all rod bolts are stretch bolts.

One reason Im going to try to get a gauge to check them.

Those rod bearings look pretty good, heres a pic of the ones i pulled out of my TDI...





as you can see they took a beating, would you by chance have the Kobelschmit part# for the 115tdi (sputter) bearings???

In regards to the vibration your feeling, On one of my first TD's, I had some wrist pin wear on #4 piston, which caused a very similar vibration you refer to.Not %100 sure thats your problem though.
