Thread cleaned up. Let's keep it civil, gentlemen. To the right of every post is a little exclamation point that allows you to report inappropriate activity. Anyone may use it if they see something that would break the rules.

Clyde you are absolutely right the cam bearing has no grooves, the grooved area is at the very back of where the rear cam bearing mounts. These bearings are so thin that the idea of being grooved is ludicrous. I've posted pics of the cam bearing and the grooved area at the back of the engine block.

Are those slots in cam bearing for oil? Are the slots what is meant by grooves in bearings? If oil travels from grooves thru slots, does that mean you don't have to turn motor to get oil in there when spinning with drill?

The slots feed oil into the passages like the grooved area in back of the block in the second pic, one passage goes to the lower part of the engine block and the other leads up to the right cylinder head.

What I'm trying to determine while helping this poster and trying to learn is: Does the oil get to the cam shaft from the grooves and thru the slots? Doesn't the cam shaft go into/thru that bearing? I'm trying to determine if there is flow with the drill pump method no matter where the cam shaft ends up when motor shuts off.

What you need is to look at is an oil flow chart on these engines, oil does flow up from the filter to the grooved are on the back of the block through the slotted holes to the cam and another passage below the cam that goes to the front of the block for starters.

I'm baaaak! I took a break for couple days from truck project. I guess I missed some good engine engineering intellectualizing from the more experienced members. So where do I go next. Do I put the distributor back in and turn engine by hand and wait to see oil rise through the rockers? Or do I continue and see if I can get the rise from drilling the oil pump.
Or do I just connect battery and try turning the motor with distributor in and spark plugs out.
Thanks.

Do the drill for one full minute or oil flow, whichever is sooner. No oil? Turn over with starter, dizzy in/plugs out/oil squirted on rockers. 7 seconds at a time. no oil? Punt. Oil at any test? start it per previous caveats. (including gauge monitoring)
