Haven't heard anything about Moss's oil pumps, but if they're made
by County you have reason to be cautious; County water pumps are
notoriously bad for a number of reasons. When I rebuilt my BJ8's
engine I sprung for a DWM 'high capacity' oil pump which, with the
exchange rate at the time and coming along with other parts was
competitive. Inspect the pump drive shaft; they can wear and you
might need a replacement (IIRC, the DWM shaft was <i>considerably </i>cheaper
than Moss's).<br>
<br>
I have a feeling there may be something else involved as well, like
bearings, but since you rebuilt the engine presumably you replaced
main and rod end bearings and checked clearances carefully? What
viscosity/brand oil are you using?<br>

<div>Hi Robert, you are the second person that I have heard of
who had that problem with "cheapo repo" push rods.
<div dir="auto">It seems that those that are currently
available are produced with too small a diameter of the cup
so they seize on the rocker ball and break off.</div>
<div dir="auto">I would recommend that you inspect all the
rocker ball ends carefully then install a set of good used
push rods to prevent further problems. </div>

I rebuilt the engine last year I did not replace
the oil pump because I had good oil pressure.
Currently, from time to time, while breaking in
the engine I am driving the car round trip 20-30
miles down the Tamiami Trail which is an open road
for that stretch.. On a recent trip, the weather
was cool, so the oil pressure was running 35 to 40
psi while the engine temperature was going up to
180 at 3000 rpm. At 4000 rpm the temperature
climbed over 180 degrees and the oil pressure
dropped below 30 psi. . I am considering
replacing the oil pump and remember that there is
a discussion about the quality of Moss pumps.
Maybe I should buy the rebuild kit and change
gears?</span></p>

by the way, on the last run all hell broke loose
