Engine Noise After Clutch Replacement


Recommended Posts

I took my car to a garage to have the clutch replaced. The guys there are friendly, knowledgable and competent but are not Porsche specialists. Now I can hear some strange noises when the engine is running. Sounds kind of like a squeaking / rattling noise and I get the odd deeper rumble every now and again that I am not sure is related or not.

I am guessing something didn't quite go back in correctly in the engine. Can any of you experienced people out there suggest some likely places to look at?

Car is 2001MY Boxster 2.7.

Can you post a sound file?

If we cant hear it we cant diagnose it

Hi Glyn - well I have my answer - this morning there was a huge clunk. The battery light came on. The power steering stopped and the temperature gauge shot up to 120+! I took it back to the garage and we looked in the engine bay.

The cause of the noise and all the above was that water pump pulley wheel had sheared off! Guess it must have just been a coincidence that this all happened at round about the same time as the clutch. Oh well can't complain as these are really the only two things that have gone wrong in 5 years.

Joesan, at least you have found the fault, i was struggling to think of anything that could have gone wrong with the clutch change that could create the sound you described, the only thing would be a faulty release bearing or a problem with the flywheel (dual mass) but the sound would be completly different between the two.

All in all your sorted - and not a too expensive thing at that

Well the water pump flywheel has been replaced but the mechanic says that the car is still going into overheat very quickly. If I have damaged something in the engine would fault lights be lit? I ran the car to the garage after the pulley wheel broke. That means I probably drove for about 10 minutes after the breakage. That doesn't seem like too long a time or enough to cause supplementary damage - is it?
