I am so glad that i found this forum, as i need some good 993 advice.
9 months ago i purchased a 95 cab with 66,000 miles from a local Porsche dealer and paid to certify it for the one year warranty($2500). This was the best $2500 i have ever spent. Upon certifiying the car they found an oil leak and pulled the motor and re-sealed it. The warranty has also covered a bad ignition coil and a bad a/c head unit.
I have also put in a new clutch and flywheel at 68,000. The car now has 76,000 miles on it and is an absolute blast to drive(daily).
The car is using a quart of oil every 800-1000 miles and i have mentioned the higher usage to the service dept. and they tell me that all of these cars use different amounts of oil and not to be worried, that when they re-sealed the motor the tech.s would have replaced the valve guides if they appeared worn. Does this sound right? or what tests could i have performed to test this short of opening up the motor. The motor runs great and shows no sign of any problems.
Am i over the hump as far a major service issues or am i just getting started? i am seriously addicted to this car and could only replace it with another. Do i sell it and get another maybe with lower miles?
sorry for the long post

I'm not an expert, but from what I've read on this board
800 to 1000 miles per quart sounds high for a 993.
You should ask the dealer for compression and leakdown tests.
They might balk, seeing as if they find worn valve guides they're
going to have to cover them under the warranty...Which would
definitely make that warranty the best $2500 you spent. I also
understand that carbon buildup on the valves themselves can mess
up the seating of the valves and let oil through.
Good luck!!
BTW...Out of curiosity what symptoms did your car display
to warrant replacing the ignition coil?

under moderate acceleration the motor would just instantly lose rpm's, it actually would happen quite violently. it would hit about 4000rpm then just drop down to 1000, if i didn't back off the throttle it would stall. the check engine light would never come on and it would only happen at random. The first time they replaced the dme, and then it came back about 2 weeks later and they replaced the ignition coil it appears to have worked as it hasn't happened since(4 weeks).

To answer your question about other likely issues, check the AC and oil cooler fan ballast resistors. They are very common points of failure.
There are many threads on this but you could start here: https://rennlist.com/forums/showthre...IY+relay+speed
Also, search for the wiring harness recall issue. This thread will help: https://rennlist.com/forums/showthre...threadid=18112
Then there's the lower valve cover gaskets oil leaks.
There may be carbon buildup issue. See for example: https://rennlist.com/forums/showthre...threadid=91905
Finally, there's the steering rack leak: https://rennlist.com/forums/showthre...threadid=98182
Don't mean to scare you, but these seem to be the most common problems so worth checking if you are still covered under warranty.
