I have a 2005 turbo S that has the 3.6. I have been told that this engine does not hane the IMS bearing problems that the non turbo 3.6 has. Has anyone had a failure. This engine built similar to the original air cooled case has that does not have this problem.. Any input about failure or problems would be helpful.

Totally different engine than air-cooled. Nothing even similar besides it being a boxer 6. No IMS problems with Turbo's. They have one of the best motors ever made by Porsche. The only issues that creep up are usually, clutch accumulator tanks, and the coolant line attachments that are glued into the motor eventually fail and come spitting out along with all of your coolant. Have them welded in and you have no worries, i think there's 6 of them. But no IMS problems.

An 05 Turbo would have the Mezger engine in it, which is completely different from M96/97 design engine that suffered from the IMS issues. The 996 turbo did have its own problems with pressed and glued coolant hose connectors that failed often enough that some tracks now require that you demonstrate you have taken steps to mechanically lock the connectors in place before letting you out on the track surface.

You bet. On my 996TT I got the full service records with the car and I could see that within the first 1k miles or so when the car was brand new the original owner took the car into an OPC and complained about the rattle -- no doubt worried, thinking that something might be wrong with his precious new toy. You can see the comments from the Porsche tech in the paperwork, stating the rattle is normal on the Turbo and nothing to be worried about. At any rate, as you said, as soon as you give it any throttle the rattle disappears immediately. When I think of the car I prefer to imagine the sound of the turbos spooled at 6K RPM instead. My first Porsche, a 4S, came with PSE....which I ended up hating in the end. Sounds loud and aggressive, annoys the neighbors. I prefer the "kill them softly" of the Turbos. They don't hear you coming on the track until you fly by them at full boost. Not a feeling in this world like the pull of that car at full boost.
