Default Engine Crankcase Pressure pushes dipstick out!
A friend of mine is puzzled. A 993 Turbo. Stored for winter. Took it out for a track day. Car runs great..except it blows the dipstick out of its sleeve? Any ideas? It seems excess pressure in the crank-case. Stuck ring maybe? Can this be corrected with a dose of chemicals?

Thanks,

may be way overfilled - just a guess but warm it up well and check the level on the stick

Check with a leakdown test.

Rob this is happening more and more.. Geoffrey "HAS" the right diagnostic answer. I would venture a guess of a leakdown OVER 20%..
