Re: oil accumulator ?
I was also looking into these to have the ability to pressurize the oiling system to prevent dry starts. My understanding is alot of wear accurs during startup. I will be going with a cooler also. My truck sits all winter and I don't want to cause any undo wear when I wake it from hibernation.
We have never had any problems in the syty V6 world of dry starts causing problems and many are sitting all winter and a number them are sitting for years. Also our low compression motors do not overly stress our crank/bearing on startup. If someone wants to have one for the look and conversation piece, thats cool. But a beneifit to a street car build isn't there.
They won't really pressureized on startup. They just relube. When you unload it prior to startup it only burps for a second and the pressure bumps to about 10 lbs for that instance then the pressures is gone. It basically pushes the oil thats in the oil circuit and replaces it with oil thats in the tank. Its the same oil that it was filled with the last time you ran your motor its not like you are getting some kind of fresh oil through the motor.
If you have it pressurized prior the winter storage it will be bleed down by spring. If you change your oil and want to change the oil in the tank then you have to unpressurize it. The only way to get oil back in is by starting the motor and letting the motor pump it back in.
I am not trying to talk you out of having one, but just letting you know they are not worth having except to support the low oil pressure for a short period of time upon deep deceleration. They last a few seconds at the end of the track because you still have the oil pump helping to add oil and pressure from the pan. If the pump wasn't working or pan totally dry, the pressure is quickly gone.
