[V8] Heads & Oil Leaks

[Paul Jager]

Is there a sort of chronic issue with the the head/block interface on the
3.6 and 4.2's. They don't appear to be as reliable as say a Porsche 928 V8
motor. Lots of talk on the European forums too about the head gaskets.

My engine may be leaking from the gasket, back end driver's side. Service
record for my '93 shows heads re/re at something like 70K under warranty
(bill $4000+) . Had this leak from the time I've had the car (105K). Just
did the distr seals etc., still leaks. I run 0W30 to reduce the flow. No
leaks when the engine is hot. I'll have to re-install my drip shields!

My theory is this block is really short, which is a design challenge. There
may not be enough surface area for a reliable seal if the surfaces are
anything short of perfect condition, and perfectly installed.
