My student w/ the 292 is getting ready to fire his 292 on the test stand, we built an oil pump primer for it and he set to work spinning it with a drill. After several minutes we still have nothing, no oil pressure on the gauge (none in the tube leading to the gauge), no oil to rockers arms, nothing. Pull the bottom off the oil pump and the primer is spinning the gears in the pump, there is oil in the pan (shows good on the dip stick??). I am thinking something might be plugging up the pickup?? Any other ideas, do we just need to prime it for a REAL long time??? thanks-

Did they fill the pump with oil before installing? It may not create enough vacuum if it is dry.

I am going to guess no, could we fill it from the top side where the oil pump shaft goes??

You can try removing the pickup tube and use an oil can to squirt oil in there while turning it slowly. You should feel an increase in resistance as it gets coated.

Did you try to run the drill in both directions?

Its a FORD. Turn the drill COUNTER CLOCKWISE.

Another thing you could check is to make sure the releif valve and spring are working properly. If the releif valve is sticking open it will cause no oil pressure.

Dan: Yes, follow up on the previous suggestions. Also remove the oil filter & put 8 oz of oil in it, let it soak in for a few minutes & then reinstall.

Dan:When you get it running don't expect immediate oil from rockers.Takes a minute or so for rocker shafts to fill with oil.Good luck by the way

Put a manual oil pressure guage in one of the line plugs on the side of the block. Possible where the stock sending unit goes. Should screw right in. Fill the oil filter AND the oil pump. I'ts an easy off and on and worth it. Then try turning the oil pump shaft from above (through the distributor hole). Watch the guage and you should soon see some pressure. Chuck in NH

dan also check the seal on the pick up tube ted told me a while back that if it doesnt seal it can suck air in between the tube & the nut causing the pump not to pick up oil from the pan, his solution was to put some grease at the outer side of the seal (the side you can see) then screw the nut in & tighten.

Howdy,
Also, you may have to turn the crankshaft a bit if you have a cross drilled cam. I used a speed wrench on mine and panic'd when I didn't get oil at the rockers. Turning the pump by hand I was able to get 30 psi or so but until I turned the crank I didn't have any oil at the rockers!
Cheers,

turned the pump the right direction and had pressure galore  , that is until oil started going everywhere - turns out his oil pump housing is cracked - we'll try her again with a different pump, thanks for all the help!

Dan: I just replaced my pump recently. It sounds like your student (if he installed the pump) over tightened it! Specs from my 57 book are; pump to block= 12-15lbs. Same for the cover. Oil tube to pan nut= 30 lbs. Inlet tube nut= 10-12 lbs. I believe it's also recommended to use a small amount of sealer on the bolts to avoid seepage. However, someone else might want to comment on that point. Remember to prime the pump some before installing it.

Looks like the housing was overtightened previously, have had a number of issues with fasteners so far on this engine - quite a few things are coming in with issues. I have close to 20 kids in class so it is very hard to see step by step what is going is going on with each project. That is not a bad thing, PATIENCE and THOUROUGHNESS is part of what the young guys need to learn... I cant (wont) hold there hand each step of the way, I tell them something is important and if they dont (wont) do it - this is what happens...we are getting there, I'll let you guys know when it fires!! thanks-

Dan,
Comment re: young guys & patience sure brings back memories. Before I was old/flush enough to work on the real thing, I used to build models. It took a long time for me to finally "get" the importance of letting the paint dry thoroughly before assembling everything (after all that tedious effort, I just couldn't wait to finish it).
Also, if I had to recommend another important life-lesson to emphasize: Kids CANNOT learn too early, the truth about "Murphy's Law"! Youthful impulsiveness can be a killer.
