just freed up a motor thats be idle for 25+years,i dropped the pan and cleaned all sludge out ,i pulled a couple of rod caps and everything looks ok,this motor has floater bearings not inserts,i would like to prime engine before cranking with no plugs,is there a easy way to prime a flatty? and and help would be highly appreciated,,,thanks al
 
What I do is to hook up a coffee can to a fitting at the oil pressure gauge sender location and dump in the last couple of quarts of oil there. This takes a while as the oil trickles in, and of course you want to do it right before startup. Put the sender back in and go to it...priming this way I see the hand on a mechanical pressure gauge start moving on the first crank and engine goes from there to full pressure instantly when engine lights.
 
Oldskool,
Most O'Reilly Auto Parts have rental tools. Ask your local store if they have a Pre-Lub Tank. I don't remember the correct name or the tool number, but they can look it up on their computer. What is neat about this set-up is that you put oil in the tank and pressurize it like a tire. Check the tank pressure with a tire gauge and set the pressure to some value above the engine's oil puimp relief valve. A hose and fittings are included with the tank. Connect the hose from the tank to one of the ports at the left rear of the block and install a 100 to 150 psi pressure gauge in the other port. Slowly open the shut-off valve on the tank to send pressurized oil through the engine. Watch the oil pressure gauge. Once oil fills all the oil passages, the engine oil pressure relief valve 'should' open. Note the pressure. If you have a stock relief valve, the pressure should be approximately 50 psi. If someone installed a high pressure pump/relief valve, the pressure will be approximately 80 psi. If you don't want to mess with checking the oil pump relief valve, just pressurize the tank, hook up the hose, open the shut-off valve and fill the system.
 
Keep it simple, do as Bruce says. Just remove the sender and fashion a funnel to get a pint or quart in the system. Reconnect a mechanical gauge where the pressure sender goes and crank it over. Good pressure will show in a few turns. John
 
Keep it more simple. Put the oil in. Pull the plugs and hit the starter. Let 'er rip turning it over to build up oil pressure in the system. My 2 cents worth. What can it hurt? The only heat you are generating is friction from the rings and if all of that is wrong and binds up, well, it would not have run long anyway. Other heat that can build up is the starter so keep it all in perspective.
 
I would Pre-Oil the engine with the pressurized primer or with a can or funnel thru the fitting at the rear of the block. THEN, I would put some oil in each cylinder and WITH the PLUGS OUT and Crank the Engine with the STARTER to get everything all lubed up BEFORE you attempt to fire it. It should be just fine.

If when you DO NOT get oil pressure while cranking the engine, stop and investigate.



Good Luck and be sure to let us know how you make out.

don't have an o'reilly auto parts in my area,just napa ,autozone,that pressureized system sounds great,i will check with some local engine rebuilding shops asap..thanks guys al
 
My C59A had sat for quite a few years. I pulled the plugs and squirted oil in. Then turned it over by hand quite a few times. Then I hit the starter and pressure came up on my mechanical gauge almost instantly.
 
Get your self a $10 one gallon pump up garden sprayer. Cut the spray wand off it. Disconnect the inlet tube from the filter and clamp the sprayer hose to it. If you dont have a filter use a hose barb fitting in place of the pressure sender. Dump a couple of quarts of oil in the in the sprayer thank and pump it about 20 strokes. The oil wil get pushed in to the gallery. Release the pressure from the tank by unscrewing the pump BEFORE all the oil is pushed out of the tank. You now have an engine primed with oil. Reconnect the filter or replace the sender and fire it up.
 
thanks 41ford1 i will shoot up to home depot today and pick one up, and will remove the sender and put a gauge there i have an oil filter and hookup the pump to the inlet,normally i would just throw oil in it a go for it but the car has beeen setting for 25 plus years and im sure all bearings are bone dry by now,,i will post results asap,,thanks guys for alll your input...regards al
 
oil in the cylinders and crank the engine without spark plugs...rags over spark plug holes....after priming the system as you plan....good luck....Mike
