I did this to my 2007 Cayman S (which carries the large bearing) about 3 years ago.

Supplying the bearing with pressurized oil is (debatably) the best thing you can do to keep this bearing from a premature death.

Good luck.

"Debatable" is a good way to put it...........

My car is the 2004 boxster S anniversary edition

It sounds like a ticking time bomb

I was told by a Porsche specialist near me to change oil to 5W40 to help reduce the probability IMS failure and also to change the oil every year regardless of mileage

It cant be that bad as this new engine fitted by Porsche has done 50k

That is a factory rebuilt engine. Base upon the time frame, it has the non serviceable IMS.

I previously had a 996 that had an IMS failure. Made me very gun shy. Took my 2004 986 LE down to Pedro for the DOF at 60K. Now at 101K and all is well. It ain't cheap, but new engines are $15K to $20K.
