Briefly, 1500 miles ago, I installed a Piper cam as part of a complete engine
bay restoration (a mild regrind) that I purchased from British Parts
Northwest.) The engine idled and ran perfectly. However, I became concerned
over having to adjust the valves - primarily the same one - three times during
over this period. When I did it last week, it was obvious that I would soon
run out of adjustment since the screw was now flush with the nut. Today, I
used a dial indicator to measure the valve lift and compared the reading with
the specs. of the new cam. No question about it, at least one lobe is bad. I
plan to follow Hemmings instructions for removing the cam without removing the
engine. It's "killing" me to have to dismantle my pristine, show quality
engine compartment.
I plan to contact BPNW and discuss the problem. I'll report back on what they
say and what they do as a result of this defective cam ( I also purchased new
lifters, push rods, bearings, pistons and much else from them). I realize that
this could have been an anomaly, but at this point, I don't recommend that
anyone else buy a reground cam. I'll reserve comments as to BPNW until after I
talk with them.
I do not intend to buy another reground cam. I'm very interested in hearing
your opinion and recommendations on brands and grinds. I would like a higher
than stock performance cam, but I want a good idle - no lope. Goodparts?
Moss?
Thanks in advance for your help. I wish I had sought it before I bought the
one I purchased.
