HI Anthony. that's a common mistake people make........they hear 'clutch pedal' and regardless of which way it is when depressed......quiter than when release in neutral, or noisy ........they automatically say 'throw out bearing.,'

in a normal world.........a TOB will be noisy when you push in the clutch pedal. If you find this opposite scenairo ............................engine running in neutral, and you push in the clutch pedal it gets quiet, you let it out, it gets noisy ......... what I usually think of then is transmission input shaft bearings. The trans input shaft stops turning when you push in the clutch .......... hence the quiet with the pedal depressed.

there is no adjustment on the hydrualic clutch of a vanagon ..........or 'not normally, ever'. If there's a bit of freeplay at the top of the clutch pedal travel..........no adjustment is needed, period. They are perfectly self-adjusting .....very nice design. people do have trouble bleeding them sometimes. and there is a spot on the clutch pedal that wears badly ...........the pivot point for the clutch master cylinder clivis pin ....... up under the dash where you could never see it .........it's a metal-to-metal thing with no lube really , except what the grease they put on that point at the factory. You can spray up in there blindly to some affect. When this spot wears, the symptom is lots of clutch pedal free play at the top of the pedal travel. It should be like 1/8th to ........up to half an inch is ok..... but syncro's suffer from that.....wearing of that pivot point on the clutch pedal.

The push rod to the clutch master cylinder is adjustable for length .... but it's an awful adjustment to have to make. IF they were talking about that adjustment, that would make sense. normally though.........the clutch master cylinder push rod length never needs to be adjusted. and if the clivis pin pivot point is really worn ........the real repair is to fix that, not to adjust the push rod length longer to compensate........though that will work, it's just not a real reapir. It's a bitch to remove the clutch pedal assembly to repair or replace that part too, btw.

I wonder if they didn't hang the engine carellessly off the trans input shaft or something like that, and cause some damage. A Syncro is a " bizarre, too much stuff jammed in there, hard to work on thing' ..................to a shop that isn't familiar with working on them. I hope it gets resolved easily.

I recently had some work done on my '89 Syncro, and the shop said the clutch slave cylinder was leaking so they replaced it. Then they did tell me that they had trouble getting it adjusted.

Now it makes a medium pitched noise when the clutch is released, NOT when depressed. In other words, when I depress the clutch pedal the noise goes away.

It didn't make any noise before they worked on the clutch. In yesterday's posts from another list member, people suggested his problem was throw-out bearing, but his made the noise when the clutch was depressed. Just the opposite of mine.

Any ideas?
