No oil pressure HELP! engine on stand. *Updated*

[1970t1vert]

New everything. I have engine on stand. Spark plugs out. Pushrods out Valve covers on.. I am using a CB maxi flow in/out 26mm gear pump and remote filter. Break-in oil in engine case. I packed the pump at assembly with vasoline. I have the oil pressure switch out to check for oil flow & filled the oil filter with oil. I have cranked the engine for a total of about a minute & NO oil . I removed the fitting from the oil pump and no oil from pump. What is my next move ? ***Updated**** Removed pump cover and noted a Vasoline Dam that blocked the oil Flow.

I saw a oil pump cover plate with a big hole drilled in it the diameter and location of which matched the driven gear in the pump. Putting the driven gear in backwards so the end sticks out of the cover plate hole. Then a electric drill was attached to that end and 'revved' up to prime the engine.

I do this to prime my engines instead.. (drain plate removed and a catch pan underneath. Recycle 2 or 3 times)

Backfill the oil pump.

Use the out hose from the oil pump and put a funnel in the hose and some oil and have someone hold it vertical and then by hand turn the crank counter clockwise with a wrench. It will draw in the oil into the pump gears and then back through down to the pick up tube. There is air in there now.

Update on issue. I removed pump cover and discovered the vasoline was a good material to block the oil . Cleaned that out and I now have oil flowing to the pressure sender port when cranking over the engine. I do not recall where I read to "pack the pump upon assembly" but I will not do that again. Thank you for the replies . I was second guessing everything.

Good that you investigated and found/posted your fix.

It is often recommended to fill the pump with vaseline but it can cause problems.

In a previous occupation I was involved in actually filling petroleum jelly into retail containers. They were filled hot to get it to fill the container. If the temperature got too cool a normal stirrer (agitator) would just create a nice circular void in the filling drum.

So similarly in a gear pump, the viscosity at the temperature you are starting to try and prime the oil pump may just see the impellers rotating. Pumps don't tend to pump solids well.

So, either remove the vaseline, or try and heat it up a bit and see if the oil pump can get it to pump.

I'd "oil spin" the engine. I do this once a year with fresh oil in my backup out-of-car engines.

I take the rocker arm covers off, remove the plugs, squirt a little oil and/or WD40 down the cylinders then put an electric drill with socket on the pulley nut.

I start spinning the engine with the drill until I see oil coming from the rocker arms within a reasonable amount of time.

Lubed to sit another year in a protected environment.

Glad you found that quickly! I've never ever filled the pumps on any of the many engines I've built with anything. Just fill the crankcase and crank with pushrods removed. Always have almost instant oil pressure. Hint...no 20w-50 at break in either
