IMS Upgrade - Should I have it done

[mikefocke]

SoK, that price doesn't make sense to me. The labor to remove and replace (R&R) the transmission to get at the bearings is almost as much as you are being quoted. To expect them to add a 2 year warranty on the entire engine for almost nothing more just doesn't strike me as consistent with the experiences and costs I've read about.

Nothing wrong with the Porsche-part RMS seal if it is the latest from Porsche.

Everything wrong with the IMS bearing and seal if it is from Porsche as none of their bearing/seal revisions have proven to not fail in a small percentage of cars and when they do fail they very often take the engine down with them to the point where a complete rebuild is necessary (assuming it is even still possible).

For the dealer to assume the risk of a new engine ($10k-$14k from Porsche) for peanuts doesn't make economic sense to me as a 2 year warranty alone is usually much more than your quote.

Call the dealer and at least ask him: Does the quote include both the Rear Main Seal and the IMS bearing and seal replacement? Parts and labor? Does it include an oil and oil filter change? What warranty do I get...on the work done or the entire engine? Who backs the warranty? Is it usable anywhere but at your dealership?

Good luck.
