New lash pads, engine won't quite start

Will do mate.

Valves that are bent just enough to say they're bent, may "pull closed" against the force of the valve spring...but this will fatigue the valve stem and eventually break off the head! Doesn't take too long to happen, either. Only had one case where that might have happened that I've seen, but it was hard to tell after the carnage.

I pulled a excel motor apart after a friends engine would not make a complete rotation, he also had a bent valve, turns out driving with a bent valve is a very bad idea I found the end of it lodged into his number 3 piston lucky it didn't bounce around, so after a new head and piston it was working again
