Hey fellas, my chevy 400 is not getting much oil up in the rocker area. By this I mean when I take of my valve covers the oil does not squirt from the pushrods or rockers. I've adjusted my valves numerous times before and can get them quiet but they just seem to make noise after I drive it. I do get SOME oil up there but I thought it is suppose to squirt out. I'm wondering what would cause this. I have a high volume oil pump, all new pushrods, new roller rockers. Could my lifters be bad? would that cause the lack of oil in the upper valvetrain? When I push down on the rockers after driving it seems as though my lifters aren't pumping up....
I don't get it... I adjusted my valves correctly w/ no noise and the engine sounding good. I then take a spin and start hearing tapping from the rockers. ( I get up to 75 PSI on the oil gauge.)After taking the car for a spin I remove the valve cover and push down on the rockers and it seems just seems like spring tension from the lifter...what gives??? the engine seems like it's missing too because of the valves not opening and closing properly because of the lifters (I think). I'm running a hyd 292/512 cam. My mechanic seems to think there may be oil restrictors in the engine but i have a Hyd cam. I don't think my engine builder would have done that, although they did make some mistakes on the engine already. Please help I'm at my wits end with this engine.
