my car leaks oil when I...
put it away for the winter. I put the car away during the winter, I drive it, but very seldom, as opposed to daily during the rest of the year. When I drive it daily there are NO LEAKS at all. When I dont drive it I find puddles.
Is this common?
thanks, leo

yup but i have no idea why. You will hear the seals drying out story which makes no sense since they are not dry if oil is leaking out and oil doesn't dry out anyway . But it is one of those strange 911 things.

This is extremely common for these engines. I found the magnesium case engines (pre-1978) leaked the most, while the SC and Carrera 3.2 engines (aluminum) leaked very little, even in the extremes of winter. I'm guessing you have a pre-1978 car.

This back fill does not occur on a daily driver, so, no oil leaks!
Cure: If your engine has original tubes they must be pinched in the middle and pulled out, which destroys them. Replacement tubes, which are expandable, are available to install and work perfectly. If your engine already has expandable tubes, sometimes, with great care, they can be removed, cleaned, and fitted with new seals (which are o-rings).

Wow, Peter thanks for the explination. I have an 84 Carrera and over the Christmas holiday the car sat while I replace my intake gaskets/insulators and fuel lines. During this time there was a puddle of oil underneath. When I completed my job and started the car up the oil leaks disappeared. (my P-car is a daily driver).
Any ways thanks for the enlightenment.

I went away for a month to come back to my car with 2-3 drops of Swepco on the floor. I'm not worried about it for the reasons explained in this thread (the car just doesn't leak when used) but where might be sources of gearbox leaks? Just curious.
