Possible lifter Failure - What to look for
I got about 3000 miles on the engine now and just developed a new noise. Not the sewing machine noise or push rods hitting heads either. I can hear it in the car. I found several cars on Youtube that sounded just like mine that fixed their noise by changing the lifters. I have LS7 lifters running about .075 to .080 pre load with Harland Sharp 1.8 rockers and PRC dual springs. Cam is a 226, 222, 116 LSA. With the 1.8 rockers I am around .620 lift. Engine has never been past 5800 RPM, oil has been changed at least ever 1000 miles. I am worried that I might have a bad roller or mayber a flat spot on the lifter since there does not seem to be noise coming from the rockers. I am going to take it apart this weekend to see what is going on.
My questions are: When I get it apart, and dont see any major signs of damage is there any way to check a lifter to see if its bad? Any other things to look for?
Also I am contemplating getting rid of the LS7 lifters if one already failed. Are there any lifters that setup as easily as the LS7 that are as good as the morels?
