pushrod question
I am kind of green mechanic. I do my oil change, brakes and probably the oil pressure sensor.
The engine is making a bad noise and people told me could be that some of my pushrods and bent.
Are they easy to change? should I take it to a real mechanic?
your thoughts please

They are easy to change.. of you go the trouble of taking them out to check them.. go ahead and replace them. I think I paid about $160 for a set of 0.080" wall chromolies.
Unless you have seriously overrevved the car.. I would be surprised if they are bent.
All you have to do is remove the coils, remove the valve cover and remove the rocker arms... they are right there. Pretty straight forward. On the drivers side you might to clear a bit more room, but probably not.
You need to have the correct procedure to tighten them back up.. again, not hard but you have to rotate the motor and know how to find TDC, etc.

I am positive that I never over rev the engine.
So if not the pushrods, I am affraid a valve or worst?
Is like a clacking noise that revs up as the engine do
Thank you for your answer

If you are going to go through that.. agian you might as well check the pushrods. If you don't mind the time, pull them out and check them. Get a flat surface and just pull them out and roll them on it. It will be a pain in the *** to do it, but not a big deal.
Probably would not hurt to check your springs, valve tips, etc. Just give it a good look around. If you were to loose a spring.. it can cause you some issues..

Stock rockers are also prone to losing needle bearings. If you feel comfortable pulling the valve covers, you can check for this problem as well. The stock LS1 valve train is pretty easy to work on.

I would advise however that when torqueing, do it very very slowly if using this procedure. Gives the lifters a chance to compress slowly. That's the way I did it and no problems.Oh, btw did I mention do it slowly?
HTH,
