I was in denial. I figured my 2001 base box had gone past the "worry" zone. I had over 120k miles so I figured, "hey, I'm okay!" WRONG!!! Coming home on the I-10 on a beautiful Friday afternoon, top down thinking of nothing else but getting a haircut, buying valentine flowers for my wife and enjoying a great SoCal weekend....again, WRONG!!! Lost power, CEL starts flashing, trail of oil. Big time engine failure. My Box died at 129,666 miles. Not sure if the "666" had anything to do with it but now I'm considering my options. I only wish that my clutch had given out a few thousand miles ago. I would have had the shop change out the IMS bearing while they were there.
Once in denial but now I know...
Now I've gotta get my wife's 2002 S in for the "preventative" IMS repair before I get "twice bitten".
Jake, here I come...

Ouch...
Yours may be the highest mileage IMS failure that we have seen to date, if thats what failed.

Don't say that!! Else you'll get labeled a "Fear Monger".. I am so fed up with that BS.

Yep.. Send them both to me at once, get a group rate on the transportation and work too! :-)
Seriously, I have a truck loading today thats heading back to Cali with a 996 on board, he'll be there next week and could load you up when he brings back TWO more to see us.

Failure cause
As Jake knows, the problem with my 29000 mile '05 987 was IMS bearing seal failure, with lots of metal dancing around in the engine. The cam cover plate was cracked all the way through by the timing belt. I just sold the car today.

Blow down check on 1 and 4, air blowing out the exhaust valves strong and out the intake valves weakly. Vey little air out of the oil fill tube.
Timing seems to be spot on....
TDC:
Bank 1-3 cams:
Cams are turning:
Popped the 1-3 oil pump, 2 row chain, no slop in chain.
What am I missing?
Remember all this happened while cranking the starter.

Many will disagree, but I think you did the right thing. There is too great of a likelihood that the car was going to cost you it's full value soon with an IMS failure. Enjoy your ride.

The can of worms is about to be opened....209,000 miles on a non Porsche approved oil!!

Thats probably the reason for such success. Liquid death is a reality.

Jake,
What's the highest mileage you've seen on a 986?
