Got an 8N running for a customer the other day. It had been setting for some time. After I got it going it had no oil pressure. I was prepared to squirt oil into the relief valve as generally reccomended by this forum. I was concerned about getting some oil to the bearings quickly so I injected about a pint of motor oil into the tee fitting where the oil pressure gauge hooks up. I started the engine before proceeding and had instant oil pressure. I used one of those suction guns that is made with a grease gun barrel/plunger to inject the oil. Worked fine for me and was easier than getting at the relief valve. Just another option to keep in our bag of tricks.
