After reading every post it seemed like. I wonder if my oil pump o-ring might be the problem, that would be a pain in the ***. It sounds like the tick is the driver side back like 5 n 7 cylinders. What does anyone think about this.

It could be but are your seeing unsteady oil pressure or low oil pressure? I have yet to hear a quiet valvetrain with aftermarket cam, springs & pushrods.
I'm starting to think maybe your over-reacting a little to the typical valvetrain noise increase. Is this the first LS1 car you have done valvetrain work on & listened to it afterwards? The sewing machine or ticking noise thats RPM relative is very common with these cars once you add stiffer springs & larger cam.

Yea my oil pressure is steady, this is my first LS1 but it's loud man and it ticks when it's at operating temp not when i first start it. I wonder if a thicker oil or somethin will help, it just sucks when i spend that much money on parts and i have a problem.

Can you get some sort of sound clip or anything to better help us diagnose the issue? My guess as to what you are hearing is the typical valve train noise that these motors produce when swapping in a healthy cam, stronger springs, and new lifters. Does the car run like ****? Do you have any friends/relative with LSx cars that have a big cam, or have done similar mods?
The simple fix for peace of mind is checking pre-load. If you know the pushrods are new, valve springs are new, cam is new, lifters are new... it should be safe to assume none of these things are messed up... and that the noise you're hearing is completely normal when doing such modifications. If you check pre-load and verify it is within a safe range... then as I stated above, THERE IS PROBABLY NO PROBLEM AT ALL. Check pre-load, man.

i start mine in the morning, it sounds great... idle is perfect and she warms up nicely.
no tick.
after she's warm, i roll out of the driveway and down the street. about 5-7 minutes of ~2500 rpm cruising and a couple of lights, i hear a small tick that sounds like ONE tick, not a uniform rotating 16 ticks. that one tick gets louder and louder until i can hear it very distinctly on the freeway.
if i cruise long enough in 6th gear, sometimes it will go away... until i give it a little gas and it slowly comes back.
i can also feel what i think is valve float when its ticking... sounds like there is a 'miss' in the exhaust and there is a slight hesitation when i hit the gas.
i ordered a PR checker and some 7.35 pushrods, hopefully thats the length i'll need, cuz my dumb *** went ahead and ordered them after a nerve wracking drive home from work yesterday. lol

i had this same issue. not the new you want to hear but probably the oil pump o-ring. my car held good pressure at idle then after it got hot while cruising it dropped to about 20. took it back apart after checking rockers and pushrods and thats what was wrong.

My oil pressure doesn't drop though. When it's hot at idle its around 40 psi. When i get on it, it goes to about 50 or so. Wouldn't my oil be aerated if the o-ring was bad too.

Maybe, it's just weird. It only seems like it's the driverside though, like 5 and 7 cylinders. Alot of people on here have the same problem but i never see a post where they find out what it is. When i look at the motor it seems like it's coming from the driverside back and underneath, thats what makes me feel like it's not just a noisy valvetrain. Hopefully it's an exhaust leak im gonna mess with it this weekend.

Has anyone ever thought that it could be the shitty paper header gaskets some of us use on new headers? just a thought cause my car does basically the same thing as desribed, hopefully it doesnt still do it after my heads and cam are all done

let me know if those different pushrods make a difference.

Yea tonight i just put Valvoline 20w50 oil in and the tick went away alot, i barely hear it. I wonder why that helped cause my oil pressure is always good. Car runs great now.
