2004 986S preventative maintenance - input please

[LuvTheBoxsterS]

I also have a 2004 Boxster S and did the IMS retro, RMS, clutch, throwout bearing, water pump, and thermostat in 2012. The car had 42,000 mile when the work was done. The fly wheel was in fine shape. Did the water pump at the adivse of the garage doing the work. The pump has a plastic fin impeller. They have a tendancy to crack. Did all of this as a precationary measure. Now I can sleep better. The USD4,000, which included an oil & filter change was worht the money.

Glad to see you are doind the motor mounts. I did not do this and just had the front replaced a few days ago.

Good luck!

When the engine is out there will be the opportunity to see some things like motor mounts, belt, etc that really can't be easily accessed in the car. Some of them will obviously need to be replaced and some others like water pump, aos, etc will be necessary just on time or milage alone. better to do it when it is easy rather than on the side of the road in 3 months. so many of the small things have to have basicly the same labor to get to them that I'd change anything that is questionable.

Usually it is a given with a new clutch but make sure they put in a new pilot bearing. Just did some of what I would consider routine maintenance on my 2002S. The motor mount rubber was broken at 45 k mi. Also replaced transmission mounts due to age but they were actually in good condition and did not need replacement. There is no end to what you can do to keep your baby at peak performance other than time and your wallet.

I understand what you are saying completely. In a few years I might be looking at a 2009 Cayman to replace my 2001 Boxster base and the whole process repeats itself!

Thanks everyone for the responses! Would anyone bother dropping the sump just to inspect what might be laying in it, or would that decision depend on how the IMSB looks when removed? The car will also be getting a magnetic drain plug and spin-on filter adapter.

YES should always be done soon after buying a Boxster/996/997

Be sure to clean the oil pickup tube also.

Standard Ultra Grey sealant works well for sealing the oil sump cover as long as the sealing surfaces of the engine & sump cover are spotlessly clean.
