I had a college friend who hardened the lifters and ended up wearing
down the cam. This was a long time ago, so maybe things are different
now. Just a thought.

This is going back a few years and there are now more options available. Some
of those lifters pitted after 5, or 6 thousand miles, and some looked fine.
I decided that the ones that pitted were not hardened properlyâ?¦an assumption
I know!
I corresponded with Mike Salter who was having lifter problems of his own, and
in the end I replaced the whole set with the modified ones from AH spares
because I no longer trusted the re-hardened set- and also removed the inner
valve springs.
After a few hundred miles the new lifters looked OK, but Iâ??m about to check
them again, this time after a couple of thousand miles.
Iâ??ve been doing a lot of reading about bucket lifters, tubular push rods,
etc. and it seems that some people are saying the current replacement lifters
are wearing prematurely because they are not domed properly and arenâ??t
rotating.
Just to add to the confusion, when I removed the set that were pitting, I could
see by the pattern on the wear surface that indeed some didnâ??t seem to be
rotating, but had no visible wear, whereas the worn ones seemed to be rotating.
What Iâ??m throwing out to the list is - I wonder if anyone has experience with
the tubular pushrod/ bucket lifter combinationâ?¦or any other alternatives.
I donâ??t know what Iâ??m going to find after a couple of thousand mikes, but
Iâ??d like to be ready with a strategy if thereâ??s a problem.
And Mike, if youâ??re monitoring the list, what kind of lifters did you use in
the end?
Thanks,
Stephen, BJ8
