Can you test the oil pump by pulling the side gage plug, cranking the engine over by hand, counting the revolution and measuring the oil displaced ?

Good question Pat. I can't remember ever doing that in all my years. If I were in need of checking the working of the oil pump, I think that you could just unscrew the plug and screw in whatever low pressure gauge you had laying around into the hole to see if it worked.
I'm not sure that hand cranking would result in the pump raising the pressure enough to get oil up that high.
Hey, it's worth a try, I mean, give'er a shot and see what happens and report back.
If no joy, try pulling the plugs and just starter cranking it, I would think that would give better results.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

You would need more speed then a hand crank... use the starter motor...,.you can also loosen the oil drain tube up, when the valve chamber fills it will come out of that...it would be more delayed taking this route3~ Tudor's & 1~ Coupe

Mitch and Wiz, I have the plug out and when I crank it over by hand the oil comes out rather nicely. I have to plug the hole with my finger or I get a lot of oil on my floor. I just figured there might be some sorta mathematical formula for that. I do like your idea of taking it from the upper most level of flow, because it probably takes another 1/4 lb of pressure to get it up there.Model A's and of course the famous AA's

by plyforI've seen some small gauges that have 1/8" NPT center mounts but can't remember what the correct thread size is for the oil pump side block plug... any gauge recommendation also would be helpful. Thanks....

by Mark MaronMy buddy John Samp just changed his timing gear after dropping the pan when he found pieces, and asked a good question "How do i know if the oil pump is working or needs a re-build"? I honestly did not know how to answer..Can you guys help me out here....

by Tom HicksThe Model T does not have an oil pump. The engine and transmission share an oil pan, they are both bathed in the same oil. That oil is picked up by dippers under the connecting rods and slung around the engine. The magneto is attached to the flywheel and the bottom of it spins through the sump throwing oil everywhere. Ford had a funnel and tube system to catch some of that oil slung by the magneto...You do not have permission to view this gallery.

by Blown GasketI changed my oil today but did not pour any oil down the distributor hole as many claim they do. I have read, looked at pictures and diagrams but fail to understand the logic behind it. To me the oil would go around and down the shaft, over the pump and into the sump. Oil poured into the crankcase tube goes to the same place. If changing oil removes oil from the upper valve chamber so would letting...

by saxman657Background: My Tudor had a huge overheating issue - full radiator suddenly dumped and boiled dry, and then died on the spot. Added small amount of water to assist cool down. Once cool, filled radiator and car would not start. Later found a grounding issue in the distributor, but starting was intermittent. After all diagnostics it appeared the ignition cable (which was old) was the culprit. Car...

by Bikerider58Sludge in the bottom of the pan is common due to non-detergent oil. If 10 years of non-detergent and 10+ modern detergent oil and engine build; then it seems like the sludge would be cleaned out. I still had a good layer of about 3/8 inch.
I did not check when the pan was off, but suspect a good amount of oil is in the pan below the drain hole. With the engine tilt it seems like there...-

by dmdeatonWe may have went over some of this in the oil filter thread. I am still a little grey on how the A oil system works. The A has a oil pump but is not full pressurized? Only certain parts get the oil from the pump? Shops machine and add some internal plumbing to get oil to the cam bearings?
The B blocks have a better oil system?
thanks guys-

by copgibI ask this question in another post and got no response so I am going to try it again. My mechanic installed a oil pressure gauge next to my water temp gauge. The temp gauge works great but the oil pressure gauge doesn't register any pressure. My mechanic stated he checked and there is oil pressure but thinks I bought the wrong gauge and that a Model A doesnt produce enough pressure to move the gauge...You do not have permission to view this gallery.

by Tree growerMy engine has not run for over a year, but I can foresee a re-start in the near future. I have heard of the need to remove the distributor and fill the valve chamber with oil so that it will trickle down to the main bearings to prevent them from running dry upon start-up. Since I have added an oil filter I am comfortable with adding another quart. Question: how soon after this oiling should I start...

by DaWizardI have been working on a pressurized engine and would like to test the oil pump for both volume and pressure before taking a chance on starting the engine. I have multiple pumps to compare.
Since I have the pump out I can plunge it into oil and turn it and have it spew oil all over the place or take it for a dip in water and help water the lawn, which I would prefer. Besides, water can...-
