Ok, I called Isky who make the lifters. They told me that I most likley are not getting enough oil to the lifters to keep them quiet. My question is, why are only a few making noise?
Now here is my theory. Is it possible , the valve springs are too weak when adjusted down to eliminate the noise, causing them to Hang open slighly ? Is this possible? The tech guy at isky said that the lifters will take up to 400 psi open pressure before they will colapse., so if thats the case and the valve springs are really weak they should push open.
Anybody?
