I have my lifters out and I bleed them all* before bleeding i couldn't move any of them*

now i can move them between my thumb and index finger easily. I cleanned them out with seafoam soaking them over night.

How can I tel if i need replacement ones. I know before I pulled them i did have a little chatter up top.

here is a picture of them.

Diesel fuel is what the fsm recommends to clean them. I usually soak them for a few days than pump them up in the diesel fuel a few times than rinse them with clean diesel. From there you can prime them with oil and install. The bigger hole in the revised lifter doesn't help the lifter be quieter. It is just there so that the less crud will remain in the lifter. If you look at the size of the hole in the rocker and that it is so small than the bigger hole in the lifter shouldn't make much of a difference.

Unless in this motor is different, you do not prime lifters with oil when replacing them, results could be very bad.

Someone correct me if I am wrong on these engines.

It seems as though the people talking about it are confusing terms or that the terms themselves are confusing.
"Priming a lifter with oil" certainly doesn't make me think of draining it/cleaning it so that it easily collapses and is now ready for installation. Quite the opposite, actually.

It might be more clear if people would use the term "bleeding", without the inclusion of "priming", when talking about prepping their lifters for installation. Priming could just mean to lube up with a bit of oil - but I can easily see why someone might think that pumped up + install = good.
 
Well they better get their terminology correct, from what the OP mentions I understood that he was getting them full of oil and to me that is priming just as you would do to a new rebuilt engine.

Do not ever prime lifters before install, oiling them yes but do not pump them full of oil.

I have seen this done many times and the results can be catastrophic.
