you may have to prime it 2-4 or even 5 mins before all the lifters are full... just because you see oil rolling out doesn't mean they are fully primed. Are these new lifters or the old ones?

The only thing i can tell you , that if you replaced a roller cam with a roller cam it will use the stock push rods and rocker arms , there is no adjustmeant on pedestal mount rockers , did it have any valvetrain noise before the cam swap , i think once its primed and started they will pump up , .....Lew

If the lifters were pumped down , i don't think priming is going to pump them up all the way , when the motor starts the motion of the cam pushing on the lifters will pump them up , like a plunger , you can try turning the motor orver a few times ....

The only way I would know for sure to check is by the book, and that is with the lifters bled down. They have a special tool to get extra leverage on the rocker arms, but you could probably bleed them down by bearing down with a hammer handle on the rocker arm.

Just never seen or used that kit , it says not for compition use , i don't like press in studs eighter , i havent worked on many peadesatall mount rockers , most all my motors were stud mount , with the problem your having is whey i don't like non adjustable valves , the kit my work fine for you , did you put the rockers and push rods back in the same order , they all whare a little different , i think they make push rods that are just a litte longer for this problem

Its is a junk yard emgine that I resealed, did a quick hone, new rings, & bearings. It is a 97 5.8l roller engine. I let it run for another twenty minutes, still ticking. It's not loud like they are falling out, just noisey like they are out of adjustment.
I'm looking into adjustable valve train components at this point. Will roller rockers fit under stock valve covers?

Lew, with your tall valve covers did you have problems with the upper intake clearing them? Conanski, did you run stock lifters with this cam in the truck you put it in? I brought the extra rockers, pushrods, and lifters home & bolted them to the engine I have at home, all tight. The only differences, CAM, head gaskets ( too thick maybe?), valves(to short)... I'm debating between adjustable rockers and all their additional expense, or ordering a pushrod length checker, tearing the intake off and trying longer pushrods. I am sooo at my wits end! Then I still have the CEL and battery light to deal with...

The tall valve covers will clear the upper intake , if you want some more room you can use an intake heat spacer , you will pick up some runner length to , i use the eddy truck intake , thats really tall.....Lew
