I have this little problem that arose lately. I happened to snap an intake valve retainer into two pieces just today and had the valve stay sorta open, I'm pretty sure the piston made some slight....maybe large....contact with the valve in the brief moment after this. Lost all vacuum which was what led me to believe it was possibly bent pushrod...not too likely on hardened chrome moly rods but I went for the check and saw good ol' piston one's intake had lost its dandy little retainer. So I fished the lock and retainer out of the head and pulled off the rocker and spring to see if the valve would move freely. It doesn't move that well....Soooo, I start thinking bent valve...I know its pretty possible but maybe I'm just looking for someone to tell me that I won't have to tear the ol' heads, intake blah blah off and bash out that valve and check the guide, possibly install a new one with a new valve, which doesn't really cost much...just causes stupid amounts of down time for the work to get done in a shop if the guide needs to be bored and replaced. So, I guess I'm asking this....what are the chances that the valve is bent and I have to tear it down and put in a new valve, AND...what are the chances that the guide is hooped and I have to get it fixed up. Or is that stupid valve just stupidly tight in the first place....I already know the answer to that last question.
