Hope this isn't a totally dumb question....I am rebuilding a SBC, got it mostly done, tossed in some oil, and spun the oil pump thru the distributer hole. I was a bit concerned about the oil pump I was using. The driver's side seemed to be oiling just fine, coming up the pushrods, into the rockers, etc. But the passenger side was dry as a bone. Oil should flow everywhere, regardless of the crank or cam position, shouldn't it??
Before the re-build, I pushed a rod through all the oil passages around the cam, everything seemed to be clean.

If you look at the distbr. hole you will see that the oil galley for the pass side goes thru the distbr. hole. If the primer you used does not accomodate this as does the distributor, then there is no oil to the pass side.

Does the tool that you used exactly duplicate the lower section of a distributor housing?? Specifically the large banded area of the housing that is the first 2" above the distributor gear??

That double banded area of the stock distributor housing is actually the oil passage crossover feed to the other lifter oil galley on the passenger side. If your pre-oiler tool doesn't exactly replicate the lower section of a distributor you will get no oil to the passenger side lifters, the oil just dumps back down the distributor hole in the pan.

There should be one in every Chevy engine builders toolbox....

That will spin the pump, but the body of the distributor (and good primer tools) have a journal seal that allows the pressurized oil to pass to both oil galleys on either side of the cam tunnel.

You can make one from a Chevy distributor (except BBC w/tall deck or 348/409 engines) by either grinding off the gear teeth or removing the gear totally, then mod the upper end of the dist. to allow a drill to chuck onto the shaft.

Rotate the engine slowly as you spin the primer tool.



Optional to this is to use a pressurized pre-oiler through a port that intersects an oil galley.

They also have the primer rod at AutoZone for free through their Loan-a-tool program.
