[TR] Lifters

[Jonas Payne]

There has in fact been a problem with the lifters.  

There are some articles out there indicating a minimum Rockwell Hardness for
them,  all of the ones I got from British Parts Northwest on my last 2
rebuilds passed, although I have heard that a lot of them from this and
other sources don't.

Just something to check - order extra and send back the ones that don't pass
or aren't needed.

Hello everyone.

Want to thank everyone (belatedly) who responded to my questions about where
to send dizzies and rockers for rebuilding.  Much appreciated.

Question;  The first time I rebuilt my TR3 engine, I replaced the lifters
with new after markets.  They annealed with the cam lobes, though.  I was
running Valvoline full synthetic.  Maybe Mobil One with higher ZZT (?) might
resolve that.  But I'm wondering whether it might also be the softness of
the new lifters not up to the task of daily driving.  I sourced them about
twelve years ago for that rebuild.  Anyone know if this was a relatively
common problem?

Having sourced another (TR-4) engine for rebuild, I finished dismanteling it
this weekend.  The lifters look nice.  But is it advised to replace lifters
during a full-rebuild (always thought so, since I was in there), and if so,
any recommendations for high quality product?

Thanks again.
