I think I know what the problem is but I'm hoping that I am wrong. I recently had my 750 Brute Force stall out on me while the exhaust was under water. I was towed back to the truck and had it boosted to get it started to get it on my truck. I changed the oil on it and ran it 2 times, then changed the oil and filter with new stuff. It ran well and the oil is not creamy. Now what is happening is that when I run it and rev it up, a thick white smoke with a smell of burning oil bellows out the exhaust. Did I blow my head gasket or is it something else? I was hoping that it was just some left over moisture but the more I run it, the more I am worried. I heard that if it was coolant leaking in through the gasket that the exhaust would smell sweet. Anyone able to help me out?
