360 bent pushrod

well now what? Intake valve. Rod bent enough that it barely hits the rocker. Valve bounces down alittle bit on the pull from intake stroke.

Exactly what are you asking? Obviously the heads have to come off, check the valve springs, rocker arms and replace the valve and pushrod. If more than one was damaged I'd also say timing chain but I'm not sure if this is an interference engine. Disassembly is your option. JMHO.

Well this is fun. On the advice of a trusted redneck I straightend out the offending pushrod in a vice, stuck it back in, and fired the ol girl up. Runs great!

The above obviously not a permament fix.

Without knowing anything about the motor then it's even harder to say. It could be something as simple as a worn out guide. Then again it could be a worn cam lobe. Lifter preload not set right. Wrong push rod length and on and on.

I wouldn't trust it any further than walking distance. It's repairable now, possibly cheaply. Keep driving it and the repairs could suddenly become expensive.

Well here is the deal. The engine was put in the truck by the preivious owner. Picked out of the "stash" as the best running out of what he had laying around. With 10W40 and a bottle of STP it makes almost 18 PSI oil pressure at like 165 engine temp at idle. When its hot out it effectivly has no oil pressure at idle. So my desire to yank and rebuild the heads to squeeze every last revolution out of the bottom end is not huge. My current inclination is to rebuild it into a 410.
