Regardless of how they are installed lifters will bleed down after sitting. If they are squeezed gravity takes over. Lifter noise is not a one time occurrence but a repetitive one at cold.

I usually don't post my opinion , but for all the problems I have read on this website about hydraulic roller lifters, and the advise of having to break them in with 5w-30, noise issues, collapsed plungers, This shouldn't be! Nothing worse than trying to do something right and then pulling intake manifolds to fix a problem. Those lifters are not Cheap! If the manufacture had to start paying labor to fix this crap they would be out of business.

Of course it does but it bleeds out the assembly lube and helps prevent galing inside the body, especially in a dry lifter like a Johnson. I haven't had the clacking issues since doing this. It was something new I tried...always learning and trying new tricks.....

I have tried everything. Priming with no pushrods while spinning the engine over, one full turn preload 20w50 oil. They still make a little noise till it builds a little heat. I don't know If valve seat pressure has something to do with this? I run 160 on the seat &470 over the nose I just put up with it.

Try Gatorman, they are half the price, I've used them in four HP 500 Upper half rebuilds, quiet with half turn pre load. They will clear the sheet metal intake shield, and one of my customers runs the dog poop, out of his engines,,and no issues. Teague uses a lot of these lifters in there engines as well. I don't know how they will work with a crazy profile, but worked great with 500 efi cams
"Use Johnson Lifters or other high quality lifters that utilize the tie bar design in either generation engine."

I vaguely remember reading that Morels where shipped with a protective grease inside the bodies. As we all know, many things come usually with an oil protectant, and some supposedly grease. Wonder if this can be an issue ?
