Priming oil pump

Need some advice. Is there a difference between oil pump priming tools. I have one that is a shaft with no bushings on it. The other has a bushing or seal. Will they prime the pump and pump oil the same. A friend said he thinks the one without the bushing does not do the hole engine. Any advice is appreciated. Thanks

your friend is right!

without the bushings the oil system is incomplete to the upper end of the engine.

Remember,I'm not making this stuff up!

Re: Priming oil pump

the bushings just keep the shaft in the middle of the distributor hole. Either one does the same thing.....spins the oil pump which oils everything. Without any "bushings" you'll have to pay more attention to position of the drill or the shaft could walk off of the oil pump and bang into the camshaft gear.

Re: Priming oil pump

Pull the oil light sensor and the oil filter....use a pump oil can and pump down the oil sensor hole till the oil comes out where the filter is.

My Spelling is not incorrect...it is creative

WRONG WRONG WRONG

The "Bushing" seals the oil distribution chanel at the upper end of the block below the distributor and directs oil to the upper Cam bearings and the lifter bores and up the lifters and push-rods to the rockers.
Failure to use an Oiling Tool with the correct design will prevent the oil from being pressurized to the upper areas of the engine and will not really distribute oil evenly to the lower oil galleys.

Buy, borrow or rent the proper tool and a 1/2-inch medium hp or better drill for the job - a Milwakee "Hole-Shooter" is a good choice.
Install the Oil Filter, Oil and the Pre-Oiling tool and spin the tool 'clockwise', as viewed from the top looking down on the distributor shaft, with the drill - watch for oil to start coming out of the lifters and then through each of the push-rods untill you see a good stream running down each rocker to the valve - be sure to slowly turn the engine over a couple revolutions a time or two as soon as you start seeing oil reach the upper end. (helps to have a 'buddy' around while doing this - one person runs the drill, the other watches and turns the engine ...)
At that point you can pretty much be assured that the whole engine has seen and recieved enought pre-lubrication to give it a good start in life.

If you're not going to go through the above procedure - at least remove the coil wire (or coil power) a use the starter to crank the engine through it's first rotations until you see good oil pressure or the 'idiot' light goes out while cranking ...

Re: Priming oil pump

Is this correct?
This is the one the Summit website recommends after selecting my '67 327 block.

Re: Priming oil pump

So why do they (Moroso) even make/sell a priming tool for a SBC if it's not going to properly prime the entire system? Another way of asking this question is, what is the purpose of the priming tool in the link that I posted (the one without the bushing)?

Re: Priming oil pump

To prime the oil pump, not the entire system.

Re: Priming oil pump

Can I just use a gutted distributor shaft? That's what I have.
I chuck the top of the shaft (rotor) in a drill.

If you mean a gutted distributor housing, yes.
