proper lifter prep ? I was always let them soak in oil for a day or 2 , but is that enough?
Can you prime them if so is it a pain ? I only ask because i had some lifetrs fail on me and find myself second guessing .....well myself . So any tips would be greatly appreciated . thx

I've heard you should soak them in mineral spirits for a minute or two and work all the rollers free before putting them into the oil to soak. I really don't know if this is necessary or not, can anyone confirm/deny?

Morel specifically told me do not wash in mineral spirits or anything else. They are shipped with a heat sensitive grease that provides lubrication and washed out with hot oil. Preparation for installation may depend on manufacturer so I would use caution here.

Bob, so with new Morels you should just soak in oil and then install them?
I have a set of PBM lifters and they told me to put the lifters in dry to check what length push rod i needed for proper preload. Then it would be a good idea to pull the heads back off take the lifters out and soak them for a day then reinstall. I didnt like the idea of compressing my new head gaskets then taking them off and reuseing them so I got a pressure primer and pressureized my block to get oil to the lifters. Seems to work fine no problems so far.
For what it's worth my engine sat for 2 years without oil in it on an engine stand in my dining room and i didnt remove my heads to get to my lifters and they are fine. Perhaps you guys are only talking about new lifters?

Lifter prep is a different subject than pushrod length checking. The best way to check pushrod lenght is to use a non-compressable lifter. The internal spring can be removed from an old lifter & then fill the void w/ a nut & some JB weld or just about anything that will fit. Once dry, there is a lifter that will not compress & can be used for measuring pushrod length.
