Re: Engine Failure leak isolated (Catastrophic Engine Failure)

Does water jacket extend that far south? If not, what is source of
coolant? I was under impression you had ruled out head gaskets
(Message #33328).

Let us know how cam removal/replacement goes. I've messed with
overhead valve, but never overhead cam. Watch that timing!

BTW: PRV being so susceptible to vacuum leaks throughout, what is
effect of loose lower crankcase assembly?
