Hey guys, how are yall doing. I recently got a used engine put in my 97 ETC and it runs great but after every drive I notice a burning smell under the hood and can barely see some smoke, but nothing major. Well a month after I got the engine install, it seems that the oil is very low (barely any on the stick), yet I never got a low oil warning on the dash. And the coolant also seemed to dropped about an inch. I have put about 1500 miles on the car since I got it and I understand that the northstar burns oil, but I don’t think this is normal. I took the car back to the shop earlier this week and the mechanic couldn’t find any leaks and he tighten up screws under the oil pan, he said it may be the oil gasket. Then he put 4 quarts of oil in. Which I think was too much, being that oil marker is pass the brown part. When I checked the oil this morning, it was darker. I don’t know what else I can check on or what is causing the burning smell. There isn’t any oil or coolant leak visible and the car runs great. Please give me some insight if you can. Thanks a lot guys.
