That's the type of vacuum pump/gauge that I have. Have adjusted the hydraulic lifters three times. Last time I back them off as far as I felt comfortable. It's difficult to feel the resistance of the hydraulic lifters except when the are all the way down. Could be the new 5w20 oil, but I will try it again with intake manifold removed, so that I can see the lifters move.
Thanks
