Hydraulic lifters

Recommended Posts

Guest Chvyrkr

So, who know's how to properly test hydraulic lifters?

 

My shop manual has the criteria, but no procedure.

I do know that when you take the rockers loose the lifters often expand and the internal piston can bind at the top of the bore. This makes for bent pushrods or valve stampped pistons the first time you crank it over.

 

 

 

Once the pushrod is in and the rocker on, take a small hammer and tap the the rocker over the pushrod to make sure the lifter piston is free to go soft before starting it.
