[Healeys] Saturday Rant Continues

I went with a DWR-1 cam and hollow lifters.

Instead of messing around with a bunch of mismatched stuff I recommend
buying new lifters from Denis Welch. I've forgotten what they cost (so it
can't have been too much) and they are drilled and relieved to increase oil
flow to the cam lobes and reduce oil retention in the lifter. If you are
installing a fresh cam then used lifters are a bad investment.

 

YMMV.

OK, from a well known Healey restorer I was told even though two of the
lifters are original style and the other six are aftermarket, as long as the
pushrod sits at the same hieght,  just use all of them.  I can understand
that, but look at the picture.  The aftermarket lifter is the top one.  The
pushrod seat of the lifters are different.  The original style seat is
almost as wide as the inner diameter of the top of the lifter.  The
aftermarket seat has an outer ledge that reduces the diameter of the seat.
I tried fitting a pushrod in each lifter.  The fit was perfect and back and
forth movement was smooth in the original style lifter.  The fit in the
aftermarket lifter was not so good.  The lifter squeeked when rocked back
and forth.  I am not sure the ball on the end of the pushrod is fitting all
the way down for full contact in the aftermarket lifter socket 




.  This just gets better and better.  Trying not to give this motor a reason
to grenade on startup.
