Engine on + pressing clutch pedal = noise

[Mauricio]

Hi gang,
Hope everyone is OK.

Here’s Hoping you can help.  My MP Lafer, which I only get to start on weekends, started making an odd noise when the clutch pedal is pressed down, while the engine is running.  

I would appreciate any help you can provide.

Recently, I had to fix a leak from one of my rear wheels and I had my mechanic add more transmission fluid  (but that was months ago, I doubt it has anything to do with the leak).

Thanks much,
Mauricio :O)

MRICIO    You might need a new” throughout bearing ” or  clutch, that is where i would start

Just a quick thought. Take a look at your Bowden Tube. That tube needs a certain amount of bend in it. If its too little it tends to chatter when the clutch is engaged. You adjust the bend by adding or subtracting washers between the end of the tube and the bracket.

Wow. That was quick.  Thanks for your quick responses.  Could this also be caused by the ‘clutch release bearing?’

The car is in neutral. Just on and the noise occurs when the clutch pedal is pressed down.

It was fine two weeks ago.

I will ask my mechanic after the holidays, but in the meantime, I wanted to consult with you guys (the real experts).

Thanks again and have a great night!

I’m with Ray10 on the throwout bearing.  With the engine out of hte car and while you are in there replacing it, you of course will want to consider a new clutch disk and possibly pressure plate.

Clutch release bearing is the throw out bearing ray 10 was referring to. That is definitely a possibility. If it makes the noise only when shifting gears its a good sign that its either the clutch starting to wear or more likely the throw out bearing. The Bowden tube would make a chattering noise thats pretty distinct and it wouldn’t likely just start…it would have been like that for a while.newkitman40895.9370601852

Guys, Thanks for your help.  It really only makes the noise when pressing down on the clutch pedal. The car uses a 68 VW engine and chassis, I am going to assume the throwout bearing is the same as the 68 beetle.
Thanks again for your help !

You might want to look for any traces of oil showing in a streak when the engine is out to replace the throw out bearing. I would almost bet on a throw out bearing. I would also replace the clutch disk when it is apart. The disk is cheap. Buy good quality parts for the bearing. There some Chinese parts out there, and they are trouble. Good luck and welcome.

The oil streaks would indicate a leaking front main seal. The big price is pulling the engine.

Guys,
It was the throwout bearing and one of the boots was cracked.

I was lucky to find a good vw mechanic in South Florida and he has since overhauled my engine.

All I really needed was the throwout bearing and a new boot.  But hey, now I have a new engine.

My mechanic also noticed the bowden tube needed to be welded in place and that is where I am now.

He replaced the clutch cable, clutch, plate, and now the car has trouble engaging in gear (probably because of the bowden tube?)

Luckily, he will try to fix this issue this Saturday.

Thanks again for all your help!!!
