How to check for bent valves??? I plan on pulling my passenger side head off today, whats the best way to check for a bent valve??
Also i'll be checking my lifters on that side also, how do you check for a collasped lifter.

Re: How to check for bent valves??? If the head is already off, pull the valve out and roll it on a very flat surface (like a mirror or glass plane). If it wobbles, it's bent.
Another way (if head is on motor) is via a compression or leakdown test.
Or, if the valve is sitting .1" lower than the others around it (like on my '94), it's pretty obvious.

Re: How to check for bent valves??? If you got the head off you can see if the combustion chamber will hold a fluid. The lifter is a little more difficult.., you can push down on all of them with a push rod , they all should have a little spring back to them. But if they bled down this wont work . If you suspect a problem what's 200 for a set?

Re: How to check for bent valves??? So much for taking the head off today. I couldnt get the freakin header off the ORP. I got all the nuts off of the studs. I was hoping i could pull the head right off with the headers hanging there but the stupid header wont let the heads come up all the way. I tried pulling the ORP but it just wanted no part of me. I guess maybe i should heat the pipe up and see if i can turn it.
