I have an '87 951 with about 84k miles on it. It goes through oil rather fast ... about 3 qts every 1200 miles. It is not a daily driver, so most of the time it is being driven rather hard. I have never found an oil spot in the garage, so am wondering where all of this oil is going. I have not noticed it smoking, although I can not test this now because the wheels are off (waiting for new rotors to come in). Any advice on where to check for oil leaks. I have also been told that some oil use in 951s is regular. About how much should be expected?

Check your intercooler pipes. If there is alot of oil in them, it may be going through the turbo.

My car was going through a quart of oil every 300 miles when I bought it. It didn't leak any oil either. Some oil may have been coming through the turbo, but that wasn't the real problem. I was hoping it just needed a valve job, or at worst maybe some new rings. I had my mechanic remove the head to do a valve job, and to put my new turbo in. What he found after removing the head was a scored #2 cylinder wall. Not good... So out came the motor, bored, honed, 0.5mm oversize factory pistons, new exhaust valves, valve job, new main/rod/balance shaft bearings, seals, clutch, etc etc...(ie. $$$) The good news is that now the car barely consumes any oil.

Good luck.

I had a 86 944t that seemed to use up (no leaks) too much oil and when I saked Porsche what was considered the worst case but within acceptable limits they said 1qt/400mi. I assume it is going through the turbo bearing. Anyone who buy a 944t or does track events for their first time should know to check their oil very often until they get used to their car.
