Hydraulic roller lifters are now commonplace, even in some high performance engine builds. But while they handle the same job as their mechanical roller and flat tappet friends, hydraulic roller lifters have unique characteristics that demand special attention.
So when we came across this video from COMP Cams that offers a 101-style explainer on the proper care and feeding of hydraulic roller lifters, we wanted to share it with you. The video starts off with a basic overview of roller lifter tech, but soon goes into some more advanced installation techniques and operation.
And it’s pretty brief too, just under three minutes long, yet packed with valuable info. So if you’re not sure what hydraulic roller lifters are (or how they work) check out the video below.
