YOU GUYS ARE THE BEST
I've gotten the flu bug and am home sick, so no messin' with the old girl 'till Monday, crapola......
A little quick background info - I'm running KB P/Cs, and stainless valves, and everything was running smooth-as-a-pooch about 2 months ago, until a clogged fuel filter and low fuel pressure combined to overheat the motor - at about 3 grand I think it was, on the x-way. So I pulled the head, (#3 was showing 60psi at the time, when the others were at 124/125), there was a slight warped spot, and some blowby stains on the head, so I figured that was the problem. Valves looked fine, nothing 'looked' bent or broken, and I pulled the cylinder too and the rings looked great, as was the cross-hatching still on the cyl wall. (motor only has 1700 miles since rebuild, and I'm not running head gaskets, oh, and I lapped the cyls into the chambers as suggested as well.) Everything is new, and still clean and straight.
I reassembled, with a fresh flycut on both heads, and have the same problem (but it doesnt' seem to run all that bad, believe it or not. ) I left my valves a little on the loose side, but I'm a hack and could've easily messed it up as well, hmph.... I'll loosen those puppies up and do another comp test before pulling the motor again. Maybe I'll get lucky, and just have to retorque the heads, Can THAT be done while the motor is still in the car?
Thanks for the info so far,
Cheers,
Jeff
PS - dont' get sick
