I have heard about method of building oil pressure without actually starting engine. Not sure if I will ever need, but does this actually work and safe to do?
Thanks, and Merry Christmas to all!

 

I'm not sure if there is a video anywhere where GM oil charges the engines before they are fired up and dynoed. GM doesen't show a lot of there engine prep procedures. Machining, honing and engine assembly. I have seen guys using small weed sprayers and attaching them to the left front side of the engine by the oil pump and priming it that way. It's cheaper than spending hundreds of dollars for a professional model. There is always the poor man method where you pull the spark plugs, pull the fuel and ignition fuses and hit the starter and turn it over for about 30 sec. wait a few mins. and do it again. If you have just changed the oil be sure you fill the oil filter before you start, this is the most common way. If if it had been ran recently you could leave the spark plugs in and be fine. There are a lot of different methods people use. If it's been setting awhile (months) it's a good idea to pressurize if before its' fired. I think.

 

Thanks for your reply. There are videos and other post online where you floor accelerator and push starter button. It supposedly pumps the oil but does not fire engine. As said, I'm not sure if I would ever do this, but thought it might be good for really cold starts if indeed it works.
Again, Merry Christmas to all!

 

I haven't tried that trick. Years ago we used a device called an oil Accumulator, its charged while the engine is running then close the valve before the engine is shut down. Then you open the valve before the engine is started, then the engine is peoiled before starting. Its a little expensive, we used it on a 427 Chevy dry sump oil system.

 

I do that every spring when I get my "13" GS out of "moth *****" and when I change the oil.

 

I don't worry about pepriming oil on my 77, its carburated with a quadrajet it's takes 20 to 30 seconds to gas up the carburator after sitting for weeks with a mechanical fuel pump. Installing an electric pump would fix that. As far as you priming the engine cold, a oil a accumulator would ease your mind I think. I have used the Moroso accumulator without issues. Looking around I see no kits that are not mechanically operated (quarter turn valve on the end only). A person could build a setup on the car with a accumulator (1.5 or 3 quart capacity) and a 12volt electric valve (3/in) connected to the engine oil gallery with a push buttom or toggle where you charge or dispence at will. That setup would be kinda what your looking for. I found accumulators and electric valves on Amazon that a person could setup something for under $300 bucks, if you wanted to go that route. Or it could be setup off the car with the accumulator, manual valve with a quick disconnect hose to the engine. Charge the engine oil system, fire it up rechange the accumulator for next time. That would make it easier than finding a place on the car.

 

Good to know that it works. Has been quite cold recently and just thought I may try next start up. Usually start every couple weeks or so, even if not driven. Thank you for your reply. Just to follow up. I did this a couple days back. Worked just fine. Only thing to remember is brake pedal needs to be pressed as expected for automatics. Immediately had good oil pressure.
Merry Christmas to All!
