Okay just got done putting an LS6 cam springs and pushrods in my car car runs great and everything. Only problem is it has valve chatter or something checked all the soilpacks and plugs and everything. But its still chattering and chatters faster with rais of the rpms. Also my oil pressure is quite a bit lower than it was previously...

 

Did you mess with the oil pump any or install a new one? What springs are in the car, what pushrods. You do know the ls6 cam has a smaller base circle requiring you to run 7.450" pushrods correct?

 

Took off the oil pump to put the cam in and change the timing. I used the pushrods that it came with.

 

Did you tighten the rockers to 22lb ft, turn the motor over and retighten them?

did your springs come with new seats and seals?

 

Are you POSTIVE you put the "O" ring back in place for the oil pump????

 

22ft lb on the rockers yes. turn it over then rettighten no. Stock seats retainers. Pushrods are same length as stock ls1's. Oil pump o ring yes pretty sure but not 100% positive no. I just really hop I dont have to pull that waater pump and harmonic balancer off again its a bitch!

 

old o-ring or NEW one?

 

Valve chatter would come from incorrect pre-load/pushrod length or the timing is off and the valves are hitting the pistons, which happened to me a while back and fubar'ed the whole engine. Make sure you figure out exactly what's wrong by taking a look rather than just guessing.

 

I think that is your problem.

 

didnt take off the pickup tube to the oil pump. Im leaning more towards the problem of longer pushrods....Im almost positive its in time the dots are lined up and everything. But would pushroda make the oil pressure low?

 

 

holy ****.....

 

Duuude! Not good, my friend!

 

this is one reason why i dont think ill be installing my cam

 

Thats pretty bad. Hopefully you didnt damage anything else....

 

wow you have some issues.

 

ok so what could cause something like that?

 

Thats what I wanna know. Its only the exhaust pushrods the intake ones are fine. Ive got another set of push rods im gonna install them and try it again. The first time I tried to start it, it was out of time so im guessing thats what did it. Hopefully it starts right up because the second time it was running strong and all the motor was just ticking from the pushrods scraping the block due to them bieng bent.

 

Obviously your timing was off. Make sure you have the sprockets dot to dot at top dead center. Install 7.450" pushrods. If you took the oil pump off make sure you buy a new o-ring and replace it. That should solve ALL of your problems. Low oil pressure from o-ring. Ticking from pushrods.

Oh and I forgot to say. Your valves are probably all bent up. Which is definatly not a good thing.

Are those hardened pushrods in that picture. And what springs are you using?

 

dude those things look like crazy straws!!
