Accidentally broke off bolt changing oil filter. Had to take it to dealer…$1000 later ,I picked it up and there was white smoke from the exhaust for about the first 5 minutes after starting. Today I drove about 2 miles in the cool of the evening and the engine overheated to max level on dash. I checked the oil and found a thick milky substance instead of oil. When I finished checking oil, I found a puddle of white milky oil on the ground underneath….Help!!!!!
