Rocker Rollers?
Rocker Rollers? My friend looked at my car or listened to my car and he said that those were my rocker rollers. He said something about it was common for this to happen to GM cars and that they need to be adjusted I think. My car is making a noise that is hard to explain, sounds like water or an exhaust leak but I got a new exhaust and it didn't go away. I can only hear it when my car is cold and I first start it up and its on idle after the car is warm it goes away. You guys got anything for me? Thanks
could be piston slap, LS cars were notorious for having it...once it warms up the pistons expand and bam...no more noise...don't worry about it...
and the proper term is "roller rockers"...which if ur car is stock you do not have these...

The exhaust leak sound you are hearing is coming from the AIR pump. It runs when the car is cold, after the car warms up it turns of automaticlly. The Air pump is part of the emissions control system.
What does it sound like, if its a tick you could have a lifter that take a little while to pump up. When my car is on a cold start sometimes I'll get a ticking for the first few minutes and then goes away. (168k miles)

+1 on this unplug your air pump before you start it and see if it goes away!

Verdad Gallardo LOL so they aren't adjustable. great.
It's not a ticking noise, its hard to explain. I'll try to record it or something and post it.
And the AIR pump thing I will try and let ya know.

i had a ticking noise on mine that sounded like a lifter... i put the tip of a screwdriver on the valve cover and the other end in my ear to see if the noise was more pronounced in one certain area... i went over all the cylinders and after finding nothing there, i stuck it on the evap purge valve and bam!... replaced that and the ticking went away... i have heard injectors get pretty noisy too

+1 on not letting that shop work on your car...
They thought you had roller rockers (-1 for them) and they thought they could adjust things that they can't adjust (-1 more). They've apparently already talked you into lifters, which it doesn't sound like is the problem to me (-1 again). Find someone familiar with LS series motors...
Also, you say you got a new exhaust, did you get new headers? If so, the car is going to be louder regardless.

Anyways i kno it is my lifters and since its gonna be expensive to replace because of the labor, imma save up for a cam swap and just fix it and all at once!
Are you retarded? We all just said the shop is WRONG, and now you agree with the shop and think it's your lifters. Dude, you have under 50k miles and you think ur lifters are making noise? I have ls7 lifters and they are much louder then your but I don't mind it and it doesn't cause any problems. LOOK into what is going on with your car before you give them it or don't come on here saying how something else is wrong and you got ripped off for buying stuff you did not need.

what amazes more than anything is when someone asks for advice and it is given and the majority tells you what it is and you still ignore advice...
understand this...LS1's are known for making odd and or strange sounds especially when cold, period! It's normal! period! If you don't want advice, don't ask for it!

How doe's roller rockers help with a stock cam?
If you intend to swap the cam later on keep the stockers rr, as most aftermarket cams recommend the stock 1:7 ratio.
I am still learning about this stuff, so best to double check this info.
