What are the chances?
The other day I had my rockers off and when i put them back on, I didnt feel like messin with rotating the motor over and setting 8 of them and then rotating and doing the other 8. I figured since they are poly locks ill just screw the nuts back down on the exact same stud and it should be close enough for me to start it and fine tune them. Well i was wrong. I started it up and it ran but I noticed that I bent a rod. I dont see how this can happen unless that it was so loose that the rod bounced out of its socket on the rocker and and pressed on the body of the rocker. Now im really worried that i bent a valve also. What are the chances that i bent one. I have only had these heads on for about 50 miles. I really dont want to have to take them off. What is the best way to check? Thanks.

When you said "rod" I'm assuming you mean push rod. Just replace the bent one for now, and adjust the valves, the right way this time
, and see how it runs. If it runs strong, and doesn't backfire at all, your probably OK. One of the springs could have hit coil bind and bent the push rod.

Yes i did mean pushrod. Sorry for not explaining. So you dont think that it could be really bad if i just started when i get them adjusted. If a valve is bent, isnt there a good chance that it could break in half and grenade my motor? Has anyone else bent a pushrod this way? I woud appriciate some more input.

i am sry to hear that u didnt adjust your rockers b4 you started your motor, that was the first mistake as i am sure u have realized by now, but i have an 89 chevy pick up that had at one time dropped a valve becuz of a faulty spring/lock assembly and all it did was scar up the head on that cylinder, and mess up the piston and i had to have the head milled, and i had the head completely reassembled as to prevent a future failure of this nature. I have heard tho it is pretty unlikely that an motor will drop teh valve completely. but again i might be wrong so done quote me, sry i hope i have shed a lil light on the subject
