Thread: Questions About Hydraulic Lifters

I wonder what your next question is going to be.........

^ I bet its going to be how to prime our motors with a drill. LOL

They (ZZP) needs to update their web site, and they need to quit copying and pasting what the maker says on everything.

With solid lifters, yes, you need to soak them for 24 hours in oil before they get installed. I still do this on my hydraulic lifters, like we have in our motors, but one or two dry turns of the motor, the oil is out of them, but they still have a film of oil left behind on and IN them to offer some protection.

But yes, like said above, the preload turning is only needed if you have adjustable rocker arms. You are adjusting the valve lash with the rockers, which also preloads the lifter.

Honestly, the OE-R lifters are crap. You don't need them unless you spinning 7K with your motor. Maybe, not even then. I ran them in my build, and removed them later that year, only after 2K miles or so of use, because they were just too damn noisy, and for the money spent on them, I see absolutely no benefit to justify buying them. Though, the web sites that sell them will tell you "why" you need to buy them and use them. You can choose to believe what you read or hear from them. I got suckered into buying them myself.

I bought a set of used, low mileage rockers that came out of a 2004 CompG from ED, and I installed those, and didn't have to change my 1.7 adjustable rockers lash with the different lifters, everything stayed the same. They are so quiet, and smooth sounding compared to the OE-R's. I have the OE-R's sitting back in their box, getting dusty on my shelf. I doubt I could even give these away. LOL
