3.5 Engine Fix?

[Elric]

If it is not the engine per se but a minor part of it (PCV valve) that, probably, causes sudden and rapid oil comsumption leading to rod #1 failure then can it be replaced on periodic basis..say every 10K or 15K miles? I assume it shouldn't be that expensive. The question is...will this preventative measure guarantee trouble-free engine work? Is it risky to mess with PCV valve? I also read somewhere on the forum about more powerful oil pump for 3.5L engines...

There have been many theories about the excessive oil-consumption:
Oil pumping at the rings,
PCV,
Valve cover (this one happened on my Dragon),
Gremlins,
You name it.

If a $3 PCV valve is all that is required for "trouble-free" engine operation, than we'd all be in agreement.

Better to spend $0.75 on a rag and keep it under your seat. Check your oil at every fill-up and you'll be fine.
