I'm pretty sure all the work was done on the rear end side of the engine but you never know. When I bang on the cats with my palm, the sound reverberates down the pipes. It's going on the lift tomorrow - hope I don't have to leave it and I end up with an answer tomorrow.

The reason I asked about the number of Boxsters in the shop..

We label the parts as they come off each car so we don't mix up parts from different cars. We might have 3-4 cars with engines out at a time around here, and all the S stuff and 2.7 stuff is exactly the same. if we didn't label everything with the owners initials, it would end up all mixed up!!

Glad to hear they are stepping up. Heaven knows I have eaten the sh_t sandwhich on many occasions

Just part of doing business.

Well, got it on the lift today and all it turned out to be were two loose heat shields on the exhaust. Apparently this occurred when the exhaust was removed along with the transmission for the new clutch & IMS retrofit. I cannot believe that those heat shields made that kind of noise but now that they are fixed - sounds perfect!

As I mentioned, the IMS was upgraded to the LN bearing. Just for those that are interested - it's a 2002 S with 55K miles. The IMS was in perfect condition. Since I needed the clutch, I'm glad I went ahead and did the IMS though as for me, I'll sleep better.

This is the first time I've ever had to ask a technical question on this forum. I really appreciate those that took the time to respond. I felt much better and sounded knowledgeable when discussing possibilities with the shop. Thanks again!

Soo, did they not test drive it?

Brad,

Yeah they did (about 15 miles) and I drive it home and didn't hear it either. With the top up and windows closed, you couldn't hear it. It wasn't until I got home and put the top down that I heard it. When they called me to come pick it up (the first time), they said the tech had just driven it and all was good. I don't know how a sound that loud couldn't be heard when it was buttoned up. I guess it's the brand new top.

Sounded serious to me and that is why I asked where the mike was located for recording. Glad you have fixed the problem and it was not internal. Oil change next ?

Milliemax, sorry I didn't see that question. Yeah, I was in my garage with my iPhone placed underneath the rear exhaust.
