Exhaust manifold bolts are the only real Achilles heel i can think of. Rear seal is a paon but that's usually after 200k

 

ehhh even the best engines on the planet have their quirks.


thick deck heights, dry head bolt chases, robust block, huge stroke potential, more than sufficient head bolt size are just a few things that make them special.


and yea, they live nice and long, but no replacement for displacement applies there.
