Robby,
Do you have the stock cylinders on your engine? I'm using the C2 Turbo cylinders on mine and they have the issue Porsche noted some time ago with what Porsche described as "weeping" between the cylinders and heads. Weeping was described as visible oil moistness on cylinder/head but not leaving spots when parked. Lucky me, I'm the benefactor of Porsche's poor execution. Dropping the engine this Winter for a reseal.


Chris (TurboKraft),
Isn't possible to get some oil seeping past the rings when the vehicle has been sitting for a while? It was my understanding that piston rings do rotate somewhat in their respective lands during operation. Didn't the 993 engines take care of that by putting a tab in each of the lands to prevent ring rotation and ring gap alignment?
