Hello All. My 960 has been leaking oil since Christmas, but as I have been driving very little, I put it on the back burner. I thought the oil cooler was the culprit, replaced it with a used unit, it still leaks. i watch that crazy Scotty Kilmer on YouTube occasionally, and I've seen him tout AT-205 seal leak stopper. I tried a bottle in the crankcase, and to my surprise the leak has stopped, or slowed down to where I don't notice it. On a 250 mile trip she was losing around 1.5 quarts, and was smoking and depositing oil on the tailgate. I have a nose like a bloodhound, and I don't smell hot oil. The leak was apparently coming from the crankshaft at the front of the engine, not something I wanted to mess with.
