Who knew?

Oh-oh... damage? My bad!

How would I find out or detect if I damaged something by running two pcv's? Could that be the cause of the high-revs at idle? I'll straighten out the tubing situation before we run it again...

Oh, and when we started it again for a few minutes yesterday, there was a strange sound from the left-hand side, like fast pulses of air at high pressure across the edge of sheet metal... I wondered if it was an exhaust manifold gasket problem. Better check that out, too... Since I ran it with two PCV's, I might have done in the valve cover gasket on that side?

Fiscus wrote: "If its idling high you might have a vaccum leak somewhere, or you could be on the fast-idle on the carb. " What does that mean, "on the fast-idle"?

I can search for a vacuum leak, but I think I'll fix that PCV valve issue first: it might be resulting in what the carb sees as a vacuum leak, since they are both plumbed in together...

oh, and thanks for the pics, half-ounce!
