You guys remember the problem I had with the oil pump on my 3.5 litre
Rover Vee-8 engine (nee Buick Special `61-63) losing its priming and
refusing to pump?
I heard from Leyland on the problem, through their American office (now
called Jaguar Cars Inc.)  They say the problem arises from the oil filter
being placed vertically beneath the oil pump (outside the engine, on the
timing-chain cover, remember?), into which oil can drain from the pump.
A proper replacement oil filter (Unipart, i.e., Leyland) will correct
the problem.  This filter is supposed to have a valve to prevent oil from
entering except under pressure.  Now, I`d like to find a domestic
replacement that also has such a valve.
They also said that the pump would have to be "drastically" worn to
lose its priming from that cause alone.
Thanks to those who made suggestions.
