I have been researching pre-oilers, specifically the passive holding tank type that utilize an ignition on operated solenoid to release oil into the engine to pressurize the oil galleys before starting.

I found this, which looked like a really great solution for engines that haven't been started in a while. You can operate it with a cordless drill or impact. This is the smaller one of two they have.

Of course, it's not cheap.

Greg,

I think the spinach factor makes this a definite loser when compared to something like an Accusump.

If you are thinking of oiling a dry engine, just pop out the distibutor and do it the easy way.

Another advantage of TBI fuel injection, is what I do. I have a "fuel pump" switch on my "Custom Instrument Panels" dash. I turn it off, crank the engine until I see ~40 PSI oil pressure on the gage, then turn the pump on and start the engine. I've been doing that for over 10 years.

While Richard is not wrong, the same can be accomplished by simply not setting the choke on a carbureted engine. Mine will never start until I stroke the throttle (usually twice when I actually want her to start right up). So I can crank as long as I want with no threat of her starting. The small amount of fuel that does get into the engine pools in the intake manifold and waits.

Where are you trying to prevent wear? If walls and rings this does nothing. And cranking with no fuel pressure is causing dry wall scraping. New EFI cars start and immediately go to about 2000 RPM then taper down as they warm. You need RPM to throw oil up on the walls off the crankshaft. Pre oiling leaves the rings dry. I want my engines to start with least amount of crank time. So far so good.
