okay i have a ticking noise after installing the tsp 231-237 and stock ls6 heads with 7.400 hardened pushrods. the tick with come after i drive it for a few mins "20 mins", it will start off real quite then get louder. my oil pressure is shity at idle "lower than 20" but rises up to 40 while cruising.

i looked at a few vids on youtube of ticking and found an ls1 that sounded exactly like mine and a couple of guys commented the vid and said it sounded like a spark plug not tightened good.

some friends think that i need a new oil pump and the ticking is the lifters not getting enough oil to them.

WHAT DO YOU THINK!!!

I think you may have discovered the normal valve train noise that accompanies cam upgrades on Ls1's. Using a standard length PR w/o checking preload may be contributing to the noise. Welcome to the world of cammed LS engines. FWIW, an exhaust leak on the manifolds can sound a lot like valve ticking.

Was the oil pressure thatt low before you installed the new cam? and i have always heard it is a good idea to do an new oil pump w/a cam install.

As far as oil pressure, You really need an ls6 oil pump when doin a cam job. It's almost a must

Check the oil pump o-ring. Did you replace it or reuse it, if it was reused then that is probably the reason you have a tick that starts after you drive it. See if it goes away after it idles for a while.

Lots of people have cut the oil pump o ring. There's even a TSB about it. If you removed the oil pump and replaced the timing chain, that may well be the cause of lower oil pressure. You should be about 40 at idle & about 60 driving.
