how can i tell if i have a bent valve?

[dsmGSTtuner]

i have a fresh rebuilt motor and i had to put the timing belt on it. i must have made a mistake because when i had the crank timing mark lined up the cam gears wasnt lining uo right...the intake cam was on point but the exhaust cam was about 1/2 to 1 inch above lining up with the intake cam gear mark. i noticed this after i tried to crank the car but it wasnt getting spark (due to another reason) so i never actually got it to crank up while it was off timing. so i put the car back in timing and now got her to crank up fine. im kinda worried that i bent a valve but im not sure. is there any way i can tell without doin a compression test(dont have the tools)? i have the valve cover off now and i was checking out the lifters but im not exactly sure what i need to be looking for. anybody know anyway to check without removing the head?

if it will start up it might sqweek or ting towards the top end of the block other than that all i know is taking it apart or a compresion test.

yea i figured that as well but since its been rebuilt, it has alot of chatter comes from the lifters bleeding out or pumping up. i havent really ran it long enough to clear that up yet.

hmm all i can think of is a compresion test then

The cylinders with bent valves with have low compression.

A leakdown test is a quick way to figure it out. Thats how I found out which valves werent seated right on my head. I had to get a 3 angle valve job.

You can take the valve out of the head and roll it, if you see it "wobble" then its bent.

don't think that much off will cause any damage, but you would have heard a good noise when that piston came up and kissed the valve.

take the head cover off and check your valves that way for one lifter will be terribly loose if a valve was bent since it didn't come up all the way when it tried to close.

You could also do the compression test, for a belt valve will cause a cylinder not to hold any compression.

Pull the spark plugs and use a flashlight, if you see any shiny crescents on the pistons, they touched the valves.

If you have the valve cover off, look for a loose rocker, a rocker that got kicked off or a compressed valve spring with the cam lobe away from the rocker for that valve.

Line up all your timing marks.
Then stick 1/2in breaker bar and spin it to make sure none are bent.
Then proceed with compression test.

Leakdown test would be a better idea IMO... .Or as Delta said pull the valve cover.

i pulled the valve cover....no kicked off rockers or decompressed springs when they aren't supposed to be. im goin to to a compression test when i get the tool in for safe measures. thanks!!
