Setting up a @$#% Hydraulic Roller Camshaft

I am trying to set up a hydraulic roller cam. I am trying to determine the correct push rod length but don't know how to deal with the hydraulic lifter collapsing. I am using light springs but they still collapse the lifter a little. How do you set up a hydraulic roller cam? How do you deal with the lifter collapsing and changing the lift and the length of push rod needed?

I could really use some help with this. I have heard that you need to put the lifter in oil and pump it. Did that but it didn't help.

Re: Setting up a @$#% Hydraulic Roller Camshaft

Are you using the 'magic marker on the valve stem' method? I helped a guy do this once by using no springs and just holding the retainer up against the rocker while the other guy rolled the motor over with a breaker bar. Maybe you just need a lighter checking spring?

Thanks Mark,

I am using the magic market method. I am not getting much of a witness of where the roller tip is riding. I though of using a lighter spring but that would leave even less a mark. Also, I would think that the lifter does need to collapse a little in order to work. I just don't know how much.

lifter may bleed off by turning over motor --try lipstick on stem -makes it easier

Or soak the lifter in oil to fill it up?

Re: Setting up a @$#% Hydraulic Roller Camshaft

Lifter should be collapsed 0.020'-0.050" for proper pre-load under operating conditions.

Use a lighter spring and use SOFT DYKEM (Hi-Spot) on the roller part of the rocker should leave a mark on the valve.

Add 0.025" when you get your measurement

You can manually pump up the lifter by immersing it in oil and using a pushrod to pump it up if need be.

Re: Setting up a @$#% Hydraulic Roller Camshaft

You need to use a solid lifter to do this. I have one that you can borrow if you promise to return it(wasn't real cheap). You can use a sharpie, or machinists dye on the valve stem tip. PM me. Mine is for the retrofit type lifters, not stock like later model factory equipped roller cam engines.
