an oil accumulator is basically an aux pressurized oil tank , that in most cases holds 1.5-4 quarts of oil in reserve, the engine oil pump pumps it full once the oil pressures in the engines oil passages is high enough, and feeds it back into the passages under pressure if the oil pump sucks air or the oil pressure drops, these accumulators are commonly hooked to a pressure sensitive valve AND frequently have a manual, or electrically controlled over ride,that can be used to trap pressurized oil, to pre-pressurize an engine before it is started, the oil can be manually routed to the engine to pre-prime the bearings and oil passages, before starting the engine, reducing wear, the engine keeps the accumulator filled while its running , and the accumulator normally has a pressure sensitive switch that cuts the ignition circuit off if oil pressure drops below 5-7 psi.
thus you've always got oil pressure during a race or the engines ignition cuts off before damage is done, if oil pressure drops under high g-loads,that uncover the oil pump pick-up.
despite the picture the accumulators mounted vertically and usually connected to the block near the rear into a oil passage at some point.
you idle back to the pits after a race or into your garage and while the engines running you throw the manual switch to trap the oil before turning off the engine, so its there for the next start up, if you turn the engine off, it would try to refill the passages due to the drop in pressure as its designed too otherwise.(yes in most cases the oil accumulator also has a electrical control valve that traps the oil if the ignition is switched off so you don,t totally depend on a driver remembering to flip a manual switch in many installed applications.)
Id suggest you install a low oil pressure switch that cuts off the ignition,voltage
if oil pressure drops below about 7-10 psi in the next rebuild,
with a manual dash switch so the oil accumulator can retain its load of pressurized oil if you choose to do so, to use it to pre-lube the engine just prior to engine start up, when the oil accumulator and pressure switch is not being used as a safety back-up, oil supply, while racing that cuts the ignition off at 10 psi and floods the oil passages if the oil pressure drops below 7 psi.
pictures of what happened to the oil cooler and connection lines would be helpful,
pictures of the valve seats and valves and any part numbers on the valves may also be helpful

Low Oil Pressure Ignition / Fuel Pump Shutoff Switch Wiring Instructions
This is a 2 terminal switch that is not closed (current flowing) until it senses pressure above 12 psi.
Install it somewhere in the oil pressure system and route the power for the ignition system (NOT start function) through this switch. When the oil pressure drops below 12 psi it will shut off the ignition.
This is also true for starting. As the starter motor turns over the motor it will not fire until the oil pressure reaches 12 psi (this usually only takes a few seconds). Optionally a user can install a momentary switch across the #43600 shutoff switch terminals (see Longacre #45460 or #45462). To start the motor before it reaches 12 psi simply activate this switch to bypass the shutoff switch.
IF you've wondered why I suggest buying and using a well designed BAFFLED oil pan with 7-8 quart capacity its to prevent the oil from uncovering the oil pump pick-up under performance use.

How The Accumulator Works
The Accumulator is tapped to the pressure side of the engine’s oiling system. When the engine is running, oil pressure forces oil into the accumulator and compresses air ahead of it.
Figure 1: Under normal conditions, oil pressure keeps a reserve of oil in the Accumulator under constant pressure.
If oil pressure should suddenly drop because of hard acceleration, severe cornering or hard braking, air pressure immediately sends oil back into the engine. When the danger is over and the pump is once again supplied with oil, pressure in the engine forces oil back into the Accumulator where it is ready for the next emergency.
Figure 2: When oil pressure drops, air pressure sends the stored oil into the engine at the main oil galleries to prevent damage.
naturally youll want to have the required extra oil volume in the pan to fill the accumulator the first time and a gauge in the cabin to show its oil reserve pressure and a manual switch, or a opressure switch that cuts the ignition if oil pressure falls below 5-7 psi.All Accumulators store oil under pressure and automatically release that oil to the main galleries when oil pressure drops. Moroso Accumulators can also be used to manually pre-lube engines before starting to prevent cold-start scuffing and premature bearing wear.

OK I know this is thought as silly and not needed, BUT this van is most likely to sit and rust 70 to 80% of the time. It is a big fat RV van with a major drinking problem and NOT at all suited for city driving, it is a long distance runner, not a sprinter. SO I am looking in the idea of an...
