Oil usage in my 924s (944)

Rowland12 · 03:58 AM

I have just purchased a 924s (1988) and have driven 120 miles and the oil consumption is very high. Other then adding more oil what other things should I be looking for. Thank you for the replies but I have just checked the coolant reservoir and the water inside is a cream colour and smells of oil. Any help please.

Does it leak externally, does it smoke out of the tailpipe? What do you consider "extremely high"? Did you check the oil a few minutes after shutting off the engine on level ground both before and after you covered 120 miles, what weight oil, how hard were you driving, what were the ambient temperatures like, ... etc.

If you read the Car manual (Which comes with the car), on my car (Ok its a 924 Turbo and a 1979), but there it say that the consumtion could be up to ONE litre per ~600 miles! (Sorry for not knowing the litre conversion)! This should be normal.
Thats much, but that what it says.
I wonder, since my car isnt consuming any oil at all, if thats bad!?

Hrm, that's your oil cooler seals.
Check out your oil, make sure it's not looking like chocolate milk. If it is, drain it out. It will corrode the inside of your engine.
Don't drive it until the cooler seals are done (Except maybe to the shop if you aren't doing them).
If your oil is clean, then you are lucky so far. You'll be alright if you change the oil cooler seals.

Most coolant tanks look yellow (or creme) over time. You will see oil droplets floating on top of the coolant if the oil cooler seals have blown. Also a frothy residue on the dip stick. Smell your oil on the dipstick or after an oil change. Coolant smell is distinctive.

If the seals blew on the PO, he may not have done a good enough job to clean the oil out of the cooling system when relacing the seals. If you don't detect coolant in the oil, then this may be the case.

According to what I read,worn valve stem seals are also a very common source of very high oil consumption, specially if the car has been not used for long periods.
That´s why I´m rebuilding my head and changing them,my oil consumption was about 1 liter per 100-150 miles.

I agree to the cooler seals too,could be both things, cooler and valve seals.
