By looking at the lifters themselves, how do you tell the difference between solid and hyraulic flat tappet lifters? Most of the solids that I've looked at seem to have a groove in the lower body that the hyraulics lack. The middle "flexible" section of the hyraulic lifters seem to have one or two ribs vs a smooth body for the solids. Are these random or brand observations or real differences?

No one out there know?

Use a push rod and push down into the seat on the lifter with it sitting on a solid surface.

Any movement - hydraulic
No movement - solid

Thanks guys. I knew that there was a trick. The simpler the better

I'm kind of amazed that there is no visual differences though.
