I am soooo close to cranking this brand new 383 over for the first time. I wanted to make sure that there is oil throughout before starting it. So I used a Tivia (sp) engine oil pump primer. This is the type with the "bushing" to allow presurization of both lifter galleys. I spun this thing for 3-5 minutes and nothing. I check and double checked to make sure the slot on primer was lined up with the itermediate shaft off of oil pump. No oil would come up pushrods, or out of where my mechanical oil pressure gauge hooks up back by distributor. I pulled off the oil filter, and was greeted with a spew of oil (does oil get here without being pumped, just from pouring oil into block through valve covers?)

I am wondering about the thing that bolts to the block which allows the oil filter to spin onto it. Would this cause no oil to circulate past it, if it was wrong part or not installed correctly??

Please advise!!!!!

Diod your oil pressure gauge register some pressure? With a 1/2" drill motor I get 50# or better with my oiler made from an old distributor. Getting oil out of the pushrods may require some time and a few rotations of the engine.

Its a little harder to get oil to come out of the pushrods than you'd expect. My motor will run a good 2 minutes, warming up, without a single drip of oil coming out and then all at once it starts pouring out. Try turning the motor over a few times, priming for a few minutes, then repeat.

I've never used a primer on any of my new motors but I always pour the oil all over the rockers then crank the motor over with no spark plugs in it until I get a pressure reading on the gauge.

Maybe I am being a worry-wort, but if the oil pump doesn't work I am screwed. I will use the prime tool and do it longer. Does the oil first have to go through the filter before it would show up at the gauge, which is not hooked up it is just the open hole (disconected gauge).

DON'T START the engine. Oil should have squirted all over the place from the pressure gauge hole. I still have the oily shirt as a reminder. Sit tight, someone will have an answer for you.

I am assuming you have an electronic oil guage, right? If it is mechanical and you are running the oil primer and oil isn't all over the ground or interior, you have a problem.

I wouldn't worry about oil coming out of the push rods. What I would worry about is getting the oil pressure guage hooked up and working. Once you have the guage hooked up just run the primer until you have decent oil pressure. You can feel it in the drill once the pressure starts to build. Did you feel the drill get "tight" or slow down? If it still spins free you are not making any pressure and you need to figure out why, before you start the car.

Are you sure you have oil in the pan? Even with a loose pickup you should have pressure.

Are you spinning it the right way? Also, your drill should be working pretty hard once the pump is primed. A cordless drill is just about too weak to prime a motor and an electric will make you sweat trying to hold it still after a period of time.

Cool

As all have said, oil in pan, pump shaft tab in primer slot, and the correct rotation of drill motor (CW), one should have an oily shirt/chest. Even if pickup is loose as inlet is submerged. You WILL notice when pump starts to pump oil, yet might end up with a sore wrist with the drill motor kick back. As dnult suggested, use an electric motor, it will definately get warm from work. Crank engine over by hand to allow oil to pass thru all lifters if solid lifter equipped, hydraulic is not much worry.

Thanks to everyone who has responded. I called the shop where the motor was assembled and they told me to pull the oil-filter and to add a quart or so (what ever it takes to soak it) to the filter. Then put it back on and use a non-cordless drill and turn it clockwise. They said that the oil filter when dry is like a large "air-brake" and is too much for cordless drill to overcome. I will try this tonight at let you all know.

Thanks again! [img]graemlins/beers.gif[/img]

Hopefully that will take care of it. I have never tried to prime one with an empty filter, I always fill my filter with oil even during oil changes. I doubt you would have ever got it primed with a cordless it takes some power to spin that pump. Good Luck
