Q: Hemi top end started making 5loud noise.
I have an 05 grand cherokee with 5.7 hemi. I took the heads off because I started getting a really loud almost knocking sound, which I thought was coming from the bottom end but it doesn't do it cold and when I reved the motor the noise gets faster as well. Used a stethoscope and found it was top end. The heads are at the machine shop being checked out now. My question is can a lifter make a noise like that? Should I change them regardless? If so is it possible to swap the MDS lifters for non MDS lifters like they put in the 3/4 ton hemi trucks?
