Re: [Amc-list] noisy after rebuild

[Wrambler242@xxxxxxxxxxx]

No side covers on an AMC 6 :[
Mixing the lifters will quickly kill the cam. They need to stay on their correct lobes.
I've done new lifters on used cams many times with  no ill effects, however the current conditions and questionalbe lifter quality can make it all a crap shoot!
  For a new cam I'd use nothing short of Diesel grade, the old non emission grade, and a can of GM EOS for breakin. Aftermarket/replacement cam engines would all get EOS at every change if I was running them. no matter what oil I ran.
