It appears you have noticed a discharge from the air dryer. Based on the discharge you describe it is vitally important you have the airdryer serviced quickly. In all likelihood your dryer is a Bendix Model AD-2. Since a new dryer can be purchased for near the cost of a professional service, I suddest you consider replacing the existing unit with a Bendix AD-9 model which has a screw on canister to ease future servicing.

Is it normal for oil and water to come out of the tank with the plug missing.There is not any treads in the hold so I assumed it was to be left open since the waterand oil seems to be under a little pressure like spitting. There was about a 1/2 gal of water and oil came out of the tank and then it stopped. Check oil level which was OK, the water was clear so I assume it was condensation for some where. The engine starts and runs great, but I dont like the engine spitting out the oil.

What tank are you talking about? If oil and water are discharged together it sure sounds like the air dryer. Its very purpose is to remove those items from the pneumatic system. I cannot stress too greately the need to service this unit. I have never heard of a half gallon of oil and water being discharges but if the dryer is failing and you end up with oil and water in your air brakes plus all you pressure guages, air horns, water purge, step slide, etc there likely isn't enough money around to make you happy again.

I think the 2 hoses going to the tank is from the air box on the 1982 DD 6VT92 to the spitter tank. The service manual shows a pressure releave valve on the hoses from the engine air boxes, but I've not been able to locate them. The oil is black so I assume it is from the engine. The water is clear so I would assme it is condensation. I did read small amounts of water and oil may come from the air box on the 82 DD 6VT82 engines. The engine runs great and the oil level has not changed, but I'm concerned about the oil discharge. The last time I run the engine only a small amount of black oil came out when I frist started the engine.
