Re: cracked sleeve in D-series...whos got pics?
 

I think the B-series are more prone to breaking sleeves because everyone is all rev-happy with them. The all motor boys experience some failures due to twisting engines 9K+. With a D-series the ports choke and the most you typically see is 8K, with a little less rotational loading due to the lighter piston/rods.

Might not have anything to do with reality, just thinking aloud.

Also the ratio of 300 whp+ b series to d series has to be 100 to 1

what casues this piston to be that grey/white color? detonation? i would assume so breaking a sleeve with only 18psi

im going to say the coolant coming into the cylinder after the sleeve breaking, then being burnt in the combustion cycle....

argh. Why didn't I think of that? I have seen plugs like that plenty of times with blown headgaskets
