Many performance vehicles use the Accusump Oil pressure accumulator
system.   If I had an expensive motor in my van, one that was noisy on start
up, I'd be using the Accusump. I've had them in other vehicles.   They are a
basic pressure reservoir connected to the oiling system.  I had the 5qt
capacity one that stored 5 qts of oil at whatever pressure the oiling system
was under at the time the ignition is shut off.

   When the ignition key is turned, it activates a relay and valve that
releases the 5 qts of Accusump oil into the motor, pre-oiling everything
before the motor is started up...  Also useful for cars that have problems
with the sump pickup 'sucking air' during hard cornering or steep rock
crawling....if the oil pump loses pressure, the Accusump takes over and
supplies up to it's capacity to 'take up the slack' while the pump pickup
might be uncovered.

   Accusumps are available at most of the racer supply houses for not too
much $...A good thing if you have lots of money sunk in your motor or it's
getting unusual use..
