Dirk,
Thank you, kind sir, for your input. This got a little off topic, and I apologize for taking this off the beaten path....

1.) Head to cylinder oil seepage. What are the causes then? Certainly with a boxer type engine, oil can find its way towards the heads during shutdown, yes?

2.) If ring rotation isn't the issue, why did Porsche choose to put tabs in each of ring lands of their 993 engine pistons?
