I've heard this statement in the past, and it always got me wondering-
 what seals are in direct contact with oil pressure?  I've only torn
down diesels, and on these engines the oil pressure is directed to
bearing journals. I would think its that way for most engines...  So
where would the pressure that might blow an oil seal come from? The
crankcase itself??
