I took off my drivers side valve cover because there has been some ticking coming from inside the valve cover. It's consistent when I rev it up to about 1600 rpm and anything above that it disapears. A few of the push rods I can twist by hand and a few I can't. All of them need to not be able to twist or move right? These are stock pushrods and rocker arms. Thanks.

 

anybody?

 

Did you actually turn the motor over, stopping at testing each rocker arm when the corresponding lifter was at the base circle on the cam?? I would assume you did, as this would be the correct way, but you never know!

I would say that if you are running a stock valvetrain, there should be enough preload on the rockers that it is at least difficult to turn each pushrod by hand.

 

Thanks. I'll go do that and check each pushrod again.

 

You can't really check valve lash that way. Some will appear more loose than others depending on where the lifter is on the cam lobe.

 

I see. Thanks.
