Good progress today, the engine itself is done. Planning to paint it prior to running. Need to paint radiator shell separately, etc. Lots of details left.

Completed project. Built a base, added a 4 gallon fuel tank, and a battery box for a group 31 battery. Wired a panel with 3- 120 volt, 20 amp receptacles, voltage regulation via a reostat. Wired 1 outlet per phase so I can load it balanced.

I ran it yesterday for first time. It starts amazingly fast, I bet I could hand crank it. It governed good and produced generator output.
After about 5 minutes running I noticed I was getting some oil spatter out of the exhaust, not sure it was wetstacking or oil, I ran it back up to 1200, getting worse it started to run away. I fought to get a good seal on the intake to kill it, it just kept running at about 100 rpm or less, finally stopping after a couple minutes. I noticed there was oil sign in the breather in the intake, so did some testing to see if it was the culprit. I ran the breather. The atmosphere with no change. I faced the exhaust toward the ground and could run it at idle with out taking off. Continued to spit oil.
I pulled the blower and I could pour the oil out of it. I made up some plates and pressure tested the air side and really had no leaks at seals but there was some leakage out of the rotor end that mates to the governor weight shaft. There was a piece broke out of the inside where thr roll pin that holds the stub on. I am really skeptical this could cause this much oil via the splash system that lubercates it.
With the blower off, I spun the engine with starter making about 20 psi oil pressure for about a good minute and noticed no oil flow in the airbox.
Not sure that rod is even pressure feed to the small end where if a piston retainer was leaking, I did vacuum them when installed. Other thought is a broken oil ring.
I pulled a blower off another engine that I knew ran good about 40 years ago. Suprisenly it was full of oil in the rotor area, but I am going to bolt it on as is to see if the results are the same.
It would be nice if this engine had an airbox cover opposite the blower like the other Detroits, might help troubleshoot.

Mike, there is an airbox cover just to the right of the blower. With a small brass rod you can check the compression rings through the intake ports. Opening that cover should tell a little more of the story. Perhaps one of the seals on the blower is directional and is pumping oil out of the blower end plates and into the air box, rather than keeping the oil in. I am sure you will have it back up in tip-top shape soon. The amount of work that you have done to that generator in such a short amount of time is unbelievable. Were you ever able to find a schematic for your Delco generator head? I am glad that it generates like it should. It will be one hell of a backup generator when the power goes out.

Chris

Great restoration, Got me motivated to finish mine. On the outlet of the oil filter there is a needle valve to regulate the amount of oil that goes to governor and supply lubrication to that end of the blower. The oil from that end of the blower returns through a passage in the housing to the front of the engine gears and back to the pan. On multi cylinder inline 71 engines there is a restricted fitting on that line. Don`t know what the adjustment on that valve should be. Might want to check the return oil passage and the hole in the front end gasket to make sure they are not plugged. As it is a bypass filter you could close the needle, watch the oil pressure and open it till you notice a drop in pressure. AL

Maybe that engine just needs a good load for a while.
