i pulled all teh push rods and most of them are badly worn down, so i went and got a low miles core 3800 sries II for free and ive pulled the push rods from it and they look great. so the rockers and pushrods will be switched over.

should i continue to tear down to lifters ? or is the push rods being worn down the problem ?
but there is an oiling problem on the top end.

thanks

My assumption is either pressure is low causing the issue or the lifters are that gunked up that they aren't supplying oil. Since you have them, I'd replace them. If they don't work, then I think you will be looking for an engine soon.

Have you owned this car long ?

Swap the lifters. the only way the pushrods are going to wear down is if there'* no oil, and the oil comes from the lifters.

All Series II pushrods, rockers, lifters etc etc are all the same. The only differences are the pushrods and pistons. Literally.

Of course, you mean I didn't type that part? I swear I need some sort of thought to typed word device. Could post more thoroughly and faster. Thanks for the help Danno.

Yep, new cam time. I have two good stock cams from a series2 L67 if your in need of one. To change it you will need a new harmonic balancer bolt, a cam bolt, a timing chain cover gasket, and I would suggest very strongly a new tensioner. Changing a cam is easy if the engine is out of the car, if it'* still in the car you will need to lower it to slide the cam out the wheel well.
