Even though there is many threads pertaining to oil pre-lube systems I have been looking deeper into these external electric systems. I like that there is no oil filling and discharging of a large reservoir that can lead to a major fluctuating oil level in the pan. No chance of the introduction of air (cavitation) into the oil system. It does not bleed oil volume and oil pressure as canister versions can when those are used as back-up reserve system, ... i.e. hard cornering or acceleration/deceleration. I also like the adjustable oil pressure switch that can be set when to turn on and off the electric pump should the mechanical pump fail to keep up. They aren't too big either. If the aircraft guys are relying on these I feel they may be worth taking a serious look at. Depending on which model you choose, the cost can go up. Starting at $315.00 for the pump and $70.00 for the adjustable pressure switch. http://infinityaerospace.com/product/other/pre-oiler-and-back-up-engine-oil-pump/ This is just one brand of a few electric systems I am looking into.

Interesting. I have a Masterlube system that I have not yet put on the car. Have to crank the starter for 16 - 20 secs to bring up pressure on a cold start before I flip the ing and fuel pump switch. I was thinking there must be another way.
Hello Gary, if someone were to expel most of the reserve oil from their accumulator as a pre start up/pre-lube it will ultimately raise the oil level in the oil pan. With that being said, .... if the oil pan design is such that it allows oil level to rise into the path of spinning counter weights and connecting rods you will risk the chance of introducing aerated oil into the system. Not to mention if there is pressurized air on one side of an o-ring and oil on the other side you take the risk of failure. We are all aware of the good track record in regards to the big name oil accumulator systems but fluctuations in temperature of their materials and the oil can be considered. In my original post I was just saying those scenarios don't take place in an oil pump pressurized system. Larry
Thanks Larry, I've been running an accu- sump for 2 years and I can see how aerated oil can get some air in the reserve tank since it may rise to the top of the tank. I don't think I've experienced this . I activate the solinoid while staging each run so if the pressure drops below a certain point it starts dumping the oil.
^^^this. Peterson also makes a slick primer/filter mount that can be driven with a drill to pre lube. Doesn't protect against pressure drop but is a nice pre start up measure.
I wrote up a little thread some time back on that piece. http://www.v8buick.com/index.php?threads/remote-filter-mount-w-primer-pump.316539/ Larry
Every time? Sounds like a PIA. I use an Accusump like Gary P. except I have the pressure switch and electric solenoid for automatic operation. Power on engine off and you can see the pressure build and hear the oil being pushed into the engine. It only takes a second or 2 for pre-lube so there's no risk of dumping all of the oil into the pan, and then the rest is automatic.
It would be. Thats why I just crank the starter for 10-15 secs prior to the first start of the day. Once the gauge reads 10-15 lbs I flip the ing switch and fire that bad boy off. Started the last engine cold and "dry" for 5 yrs and never hurt it.
Different way of thinking I guess. It's really not hard at all but then again, I build my car with the foresight to make things like this easy. Belt off ... 90 degree cordless ... Literally seconds and viola .... Oil pressure before the engine moves. Maybe overkill? But definitely not a PITA.
I wouldn't think starters would last very long doing that. Especially the high torque models. In my opinion pre lubing before you turn the engine over would be a better practice. Depending on how long the motor sat I would spin the pump for a bit, then rotate the motor and spin the pump some more. Then fire.
I guess for a race-only deal it would be ok, but it sure is easier not even opening the hood. Also, with an Accusump-type system, you also have some protection from oil starvation when you lift or whenever. Sorry for getting away from the OP's message about the aircraft-style oilers.
I have been curious if anybody runs an accumulator on the Buick as it would seem to help if possible oil starvation but this seems very interesting to help with dry starts. Anybody running this or anything like it?
