Idk anything about the process. I heard they grind the face. Can this be done on a lathe? Or on a valve grinding machine. I know u can dress the valve tips but I’m lost from there. Thanks for the insight. Kim
If You start with the right pushrods, it'll be fine. If You've shimmed the shafts w/stk.-n/a rockers to minimum preload, You'll likely need to reduce the shims.Don't lifters and/or the cam lobes have a specific taper ground into them to promote rotation? The surface also needs to be a specific hardness as well as a specific surface finish. As difficult as it is to break in cams & lifters, it would be very difficult to meet all of the parameters needed to be successful. It would also require the pushrods to be a bit longer.
So the lifter failed? Were the cams new/used? Valve grinder maybe puts to rough of a finish on the lifter? KimIve done some with a valve grinder. The 4th time i did so 2 lobes wiped out, filled the motor with metal chips. Complete tear
Apart and rebuild needed. Like the song says "three outta four Ain't bad"
Dont take the chance !
New and used cams, refaced liter bottom.So the lifter failed? Were the cams new/used? Valve grinder maybe puts to rough of a finish on the lifter? Kim
No no, but hell no. !The lifters that I bought were supposedly new. But they are not. They do have a crown on them though. But I wouldnt use them on a new cam. Kim
