What did you do with/to your Boxster today? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

What I did today other than polishing my exhaust tips was to try and find the rattle I hear when shutting down the engine. I jacked the car from the rear and used my rubber hammer softly banging around on the muffler, the cats, and their heat shields, etc. I was not able to hear or see anything loose that would be making this noise. I first though something had broke loose inside the muffler. I might add I hear it sometime and sometimes I don't. It seems when back from a drive and everything is hot. Got me stumped!

Turn the car off with the clutch pushed in, and report back.

No rattling noise with the clutch in and turning off the engine.

It's your flywheel. I think a lot of these cars do the same thing.

A Porsche Tech said, it sounds like the flywheel. He said, sometime a spring jumps off the flywheel and it will cause the rattling. Now what I need to do is open up things and see. I can get a LUK DMF42 for just under $400.
I searched the forum for someone that may have had a rattling DMF, but no success.

Am I brave enough to tackle this job like Ben. It's a long way just getting there. Rear Bumper off, muffler off, transmission mounts has to come off, braces, etc. The Tech said today it's 7 hours of labor to replace the DMF.

Went out for a stress relieving night drive. Couldn't stop looking at her as I walked away. So much hotness happening all at once.

Several have said it's the DMF. One said, when you press in the clutch and don't hear the rattle when shutting down the engine, it's the flywheel. Someone said a spring is broken in the flywheel. One said it's the transmission.

I just cannot believe this rattle is the DMF, or Transmission. The other day after starting the engine, and the car sat in the garage for a few minutes, I started to back out with the engine at idle rpm's around 6 to 7 hundred. When slowly letting out the clutch I hear this rattle. At that engine speed is when things may vibrate, thus rattles might be heard. I don't hear this noise backing up with the engine up to temperature. My thoughts are it's the darn muffler. I have rubber hammered on it several times but don't hear or see anything loose. Dr. Know around?

I was able to talk with a Porsche Tech at the Dealership the other day when picking up a part about this rattle I am hearing when shutting down the engine with the clutch out, and with the clutch depressed, no rattle. He mentioned it sounds like a rusty release bearing. He said we see that sometime. I also spoke to a indie about the rattle, and right off he said it's the throw out bearing. He is going to check it out later this week.
