So here is whats up. ive got a rebuilt lt1 bored 30 over and its got a gm cam with .492 lift and jegs s/a 1.5 ratio roller rockers, and i just recently found out after running (idle) for a little while that a lifter had locked up. so i bought new summit lifters and installed it all and put everything back togeather and started it up.... here is what happens i start it and roller rocker dosent move and then i turn it off and there is a bent pushrod and it looks like the spring is compressed down(i am running springs that must of been upgraded from stock at one point before i bought it because thats what the machine shop told me) so my question is what is going on there and why dose it seem that way?

 

IT SOUNDS as if you tightened the rocker too tight..

 

Sounds like you bent a valve.

 

x2, maybe too tight

 

That's what I thought, but the description of what is going on is a bit hard to follow.

 

for whatever reason, the valve is not closing. its either bent or something is stuck inbetween it and the seat. have you tried spinning the motor by hand with the valve covers off?
