victoreric, Do you know which modifications, if any, the new engine from Porsche would include?

I assume the new Porsche engine would continue with the original cylinder sleeve design so that the cracked sleeve issue may still be there?

Would the new Porsche engine have a modified intermediate shaft or the old design?

Any changes to the head design that could prevent cracked cylinder heads?

Finding the answers to these questions may be a guide as to whether to get a new Porsche engine or not. It may be worth the extra cost if these key problem areas are addressed in the new engine (notice when I say "new" I am not talking about the 987 engine, just the new crate 986 engine). Of course the Porsche warranty would be nice too.

BTW, I am sure the new engine would have the revised RMS seal.

Also, another good article on engine failures via autofarm:
