I need to check my PTV clearance and from what I have read I need to use a solid lifter instead of my hydraulic lifter when I do the checking. I also need a checker spring (I assume less spring pressure).

Does anyone know where I can get these. Thunder racing (where I got my pushrod checker) did not seem to know what I was talking about.

Looking for help/suggestions.

Thanks

I made my checker lifters. I disassembled old LS1 lifters and epoxied the spring/pluger upon reassembly.

 

I personally use the lifters that are going into the motor when measuring for pushrods and checking PTV clearance. Use a spring just strong enough to hold up the valve and you won't even come close to compressing the lifter plunger. You can get springs at any hardware store.

 

I did that also the on the only H/C project I undertook. I saw no difference between using my epoxied LS1 lifters and the new LS7 lifters.
