Has anybody thought about installing an oil accumulator? I think that is a good plan tho not sure how it would hold psi over time. I'm thinking it is very helpful on the stock car in the turns if the pickup gets uncovered (I need a wider pan). It would be an unsightful addition if that is a concern/bothersome. These have a shut off valve that holds the pressure. It literally is a manual ball valve. Same thing they use on farms for irrigation lines or even your water faucet. These tanks hold something like 3 quarts of oil and when you open the valve, it pre-lubes the engine. Then you start the engine and it uses the oil pressure to refill it, and before you shut the car off, close the valve if you plan on letting it set for a while before driving it again. It its only going to set for a couple days, leave it open. There not that big overall, but I could see in something like an early A-body maybe a bit tight.

Just cranking an engine that has sat for long time....is enough to for the engine to get oil pressure....the oil light in my cars goes out almost immediately. The ones w gauges show pressure just as fast.

Just cranking an engine that has sat for long time....is enough to for the engine to get oil pressure....the oil light in my cars goes out almost immediately. The ones w gauges show pressure just as fast. My Imperial, my Super Bee, my Ram 350; I've owned them all for 20+ years. All sit for months (3, 6, 12, 24) without being started, and I do nothing other than start them and go. The longest each of them had sat without being started has been 5+ years. Start and go. They are all stock engines, ranging from 70,000 miles to 150,000 original engines with no rebuilds. I just drove the Super Bee on a 7-hour road trip to Hodge Restorations and back. I use the truck every 8-months to go haul something or move something to or from storage. The Imperial gets driven once a month or every two months for an hour or two at a time. Start and go. Just sharing what I know! Cheers.

I would rather crank mine to get oil pressure first before it fires than have it start right off. Cranking compression is a lot less than running compression and a lot easier on the components. I used to try and get it running as soon as possible after sitting but the lifters always clattered and sometimes didn't pump up even after running for a while. Since I've been cranking it until the oil gauge starts to read, I've never had another noisy lifter again. Those that say it gets oil pressure quicker are right but only because it's spinning faster and it takes the same revolutions to get it primed whether running or cranking. The real worry is the cam / lifter interface. (Assuming non-roller). That's why cranking is bad, and instant starting is good. At low RPM there's little or no hydrodynamic wedge of oil on these sliding surfaces -- this is what wipes cams. That surface is splash only, not pressure-fed.
Ether it, bring revs to 2500 immediately.
The factory never pre-lubed any engine. Assembly lube they used: Motor oil.
