This is a friend of this user and i am having problems with my 87 toyota pick-up. The other night it over heated so i let it sit for a night, i then added water and anti-freeze to the radiator. When i did that i checked the oil as well and saw that it was a dark grey color, in that i was thinking it may be a gasket problem. I then drove it about 10 more miles home added more water and let it sit for about 1 hour. i then drove it no mnore then a mile when it died again. Smoke came from the exhaust and i lifted the lid to see thei now a bit lighter grey liquid on the side of the engine and i opened the air filter to see that this stuf also came from the carburator as well. No idea what is going on. Plz help if possible A.S.A.P.
