Oil accumulators come out of the aviation world. Canton has been supplying
them to motorsports for 20 years. There ARE some engine builders that don't
like them, generally from experience with clueless drivers who open the manual
ball valve on an empty accusump at startup and rob oil pressure. So don't do
that. Either throttle the accusump until it reaches normal system pressure or
install an electric valve. Not only do the electric valves reduce the
likelihood of emptying the sump because you forgot to close the valve prior to
shutting off the engine, but they also throttle the filling to prevent robbing
pressure. That's why they are a bit expensive--they are not simple solenoid
valves, they have some trick regulator bits in them.
Summit has a barebones 1 1/2 quart moroso accumulator for $69. Add a manual
valve for $13 and a little plumbing and you're in biz. Electric valves are
about $120 and worth it IMHO. The barebones sump doesn't have a air side
pressure gauge, but you can read that with your tire pressure gauge and save
fifty bucks.
Plumb it straight to the oil gallery and you don't need much tubing, fittings,
and you don't need a check valve. Simple as bricks.
> Back when I was in the diesel engine business and before, as far as I know
before accusump, CAT came up with a prelub starter. it had a position on the
ignition for prelub and then to start the engine. To start you would turn to
position 1 and run the prelub pump then continue to start. At the time it
seemed like a good idea and worked well.
