John,
thanks for the advice. Just wanted to clarify: there's a LOT of smoke
coming out (at least, when the engine is at higher rpms, when idling,
not so noticeable). Driving down the street, I would definitely be
turning lots of heads! You still think I should give it a good spin?
How long should I give it before I should expect the smoke to quiet
down? Does good compression like this definitively rule out that I'm
having serious head gasket issues?
Thanks again!
Wes
