Our Series V (B395009965) takes an abnormally long time to build up oil
pressure at start-up. After the engine starts you can hear (I suppose its
the valve gear) quite loudly until the pressure builds then it quiets down.
If I started the car several times in the same day the problem doesn't
exist. If the car sits for a day or two between starts the problem reoccurs.
Its as if all the oil drains back into the sump and the whole system needs
to be re-primed.
I used to think that the problem was a bad anti drain back valve in the oil
filter until I tried two other filters (another Fram and a Wix which is on
the car now).
The engine was rebuilt about 2,000 miles ago (not by me). The oil pressure
(once it builds up) is 55 lbs. when cold and about 40 lbs. when hot.
Did I get three bad oil filters in a row or is there some other reason why
the pressure takes so long to build? Could a bad oil pressure relief valve
cause this? Any advice would be appreciated.
