Won the Porsche Lottery Today

[tonycarreon]

all m96/m97 engines have the IMS bearing, and that is the problem. porsche removed the IMS for the 2009 MY.

it is possible to replace the bearing in the larger shaft with an LN bearing, but requires removing the shaft from the car (your current situation).

if it's already there i'd replace it. though LN recommends replacing every 4 yrs/50k miles. meaning you'll have to disassemble again if you go with the larger one from porsche.

it all depends on if you want to roll the dice again. there are people on the forum who have had multiple failures, and those who have had no failures.

let me ask, since you have a TIP, what's your driving style? hard? easy? somewhere in between? do you let the car get near the reline, or just let the transmission do the shifting?

Unless I'm on a freeway I drive it in manual mode for the fun of it and to to keep it from lugging around like it would in auto. I avoid 4,000+ until it's warmed up and I run it hard every day ot two under the theory oil sloshing around will lube the IMSB (and for the fun of it). I don't baby it, but don't thrash it either. I've never tracked it.

Soooo Foydawg, if you've had an IMS failure that stalled the car and you need to replace the IMS and bearing what about other parts of the engine? were there any other parts that failed? Was there metal in the filter or sump or fillings in an oil sample? Does the crank and bearings look good?

Got it back today after writing a $7,000 check. The parts highlights were: new IMS w/bearing, oil cooler, engine gasket set, cylinder head bolt, timing chain, elective water pump and AOS with a host of small parts.
