SBC Emergency Engine Problem

[nitetrain4590]

So it definitely was the flywheel cover.....I have no idea how that happened(nor would I have ever thought that was the issue). I guess that it had been rubbing the whole time, and for whatever reason, when I drove it, the flywheel pulled the cover into itself and bent if toward the flywheel face. I'm going to pull the cover, and still pull the plugs and take the serpentine off and rotate the engine over just to make sure. I've got to go through my valve adjustments again, for anyone who has experience with Comp Cams stuff, the Magnum Rollers with an extreme energy hydraulic roller cam: do you guys go 1/4, 1/2 or full turn past zero lash on the base circle? I'm reading conflicting info on this. I'm going to run a compression test also just to make sure.

With the flywheel scraping against the cover for that one or two minutes: what are the chances that the billet flywheel may be out of balance with the rotating assembly? I don't want to pull the bell housing cover off, but if I'm going to do all of this now, I want to do it the right way.



Thanks guys....
