[ROVERNET - UK] P6B oil pump troubles

[Robert Thornton]

The most effective way is to remove the base of the pump, pack it
tightly with Vaseline so that it oozes out between the gears, replace
the cover. Then remove the distributor and one rocker cover. Insert your
cut down screwdriver into the oil pump drive slot.  Attach the other end
of the screwdriver to an electric drill and switch it on until you see
oil appearing at the rockers. Just using the drill without packing the
pump will not guarantee results because the oil level in the sump is
below the height of the pump. It's also worth checking the pressure
relief valve is not stuck open, which is a common problem with these
engines.

Thanks Alan ...yes the car has been sitting for the past 6 monts and I
have never removed the oil pump...the oil pressure is often slow to
prime on it's own but it always does it in short order...this time I saw
no increase within the first 5 seconds and chose not to let the engine
run any longer in case of damage. The other P6B  started and primed
quickly but not this one..first time it has happened to me in over 30
years so I think the odds have caught up to me :)

Regards
 Dennis
