Valvetrain noise
I've read some threads talking about it but couldn't find one
anyways tonight after I pulled in, I was hearing some serious valve noise. Like hardcore. Almost a rod knock but up top lol. Maybe not as bad as a rod knock, but pretty intense. Anyways point I'm getting at is if it's relatively normal for these engines?? I could really hear it with windows down and it was also changing with RPMs. Fwiw it's an ls3

Mine has a lot of valve train chatter but I have headers and I could barely hear it before the headers. You might want to have it looked at by the dealer. LS motors are noisy but what you describe is excessive for stock.

That was with the trunion upgrade? wow,. What rpm were you running. That kind of scares me because its not like your cam was huge.

I have valvetrain noise too. Like it has been said in previous threads..these engines are very noisy. If you think it is an issue, have it checked out by the dealer, if not..then continue to enjoy your 5 year, 100,000 mile powertrain warranty

started making loud ticking noise(s) and then a few days later, sounding like a ticking time bomb with a loud knock coming from the upper part of the engine. I was positive a pushrod was bent, rocker loose, spring broken or lifter failed...but...
My car started making a noise similar to these last night after I ragged on it on the expressway last night now dont know what the heck it is?? Hope its nothing major. |
