Building oil pressure on new build, FIXED !! weird problem discovered Options

[barefoot]

New 2L build case align bored and gallery plugs replaced with threaded plugs so i know everything's clean in there. New CB type 1 oil pump mod the fit Tp 4. Temporary oil pressure gage fitted, Valvoline VR-1 20W-50 oil and all bearings pre-lubed with assembly lube (the red stuff)
With my test rig I'm trying to make sure oil pressure observed before trying to fire the engine. Spark plugs pulled, so easy cranking. I've now cranked it over perhaps 30 revs so far and no pressure showing yet. I did not pre-fill oil filter (not sure why that's a bad idea) I pulled filter and there was ~ 1/4 full, so it seems oil's getting somewhere, but how long does it take to build pressure ???

Just let the starter rest a bit. You can also build a Pressure lubber.

Gavity will prelube your engine very well even have oil dripping from the rocker arms.
Take a 1 QT or 1 litre oil jug. Remove the cap and drill a hole in it and thread the hole for 1/4 pipe. Buy a 1/4 pipe hose barb and thread it into the cap. Using wire or welding rod etc twist up a basket to hold a 1 qt or 1 litre oil jug upside down with a hook to hang it. Buy some oil proof hose (clear plastic line is ok too.) Obtain a hose barb with 8mm thread on one end. Remove the oil sending unit or fitting from the engine and screw in the 8mm hose barb with the hose attached and the cap on the other end. 3 feet works about right. Get your fresh oil jug and place it in the wire basket you made. Unscew the cap and screw it on to the cap attached to the free
end. Hang the oil jug upside down. Take a sharpe awl or knife and poke a hole into the top of the oil jug. (Actually the bottom but it is now facing up) This lets the air in and the oil out. Go for lunch. When you return the oil will have traveled by gravity down the hose or line right into the oil galleries of the engine and dry start ups are eliminated.

You can also use air pressure in that little hole, but if you have a loose fitting it can cover everything in oil in a matter of seconds. (IMG:style_emoticons/default/headbang.gif) BTDT

Can also do the same thing with a pump herbicide sprayer. I have one of these I built to fill Miata Transmission, same concept just a different way around.

Oh don't forget to remove the amount of oil out of the engine you have add via this method.
