Hey guys, first post for a newbie.
I put heads on my 5.7 ltr after it ran hot. like a fool i did not replace the lifters/pushrods. I went to adjust the lifters while the motor was running and noticed that three rocker arms on one side had very little oil flow. Also no oil pressure is registering on the dash, but i thought it was only the sending unit. Does this mean ive just got clogged lifters? Can i just replace those lifters that have low flow? Will an oil additive clear them up if i let it run or drive it gently? I havent did the final adjustment while running, will the the lifters being torqued to much cause the oil flow to be very low? Im scared to let it run even to adjust them to find out..

Advice.. please...
