The car started tapping really light, dsmlink started registering the noise as knock. I changed the oil shortly after. Noise gets worse.
It doesn't seem to be rod knock and kinda sounds to high in the motor to be a crank bearing. Oil pressure is great, nor did it change as the problem was noticed and got worse. For that reason I would expect it to not be any bearing problems.
So I pull the valve cover and pop the rocker arms off to check the lifters. 4 of the 16 lifters are pumped up. What would cause 12 lifters to not fill or maybe collapse??
Or any ideas??
I'm changing the lifters as we speak with a set I had laying around to see if anything changes. I don't want to ruin these ones if there is a problem with the oiling system.
