Got a call about an M35A2 that was blowing smoke at idle and mid throttle, and blowing oil out the exhaust. At highway speeds the exhaust cleans up until you bring the rpm's down, and then the smoke comes back. Local garage had changed the oil and added 2 extra gallons of oil to the crankcase. (
IT'S CALLED PULLING A DIPSTICK, YOU DIPSTICK!!
) It was run like this for a day or two before it started blowing smoke and someone pulled the dipstick and discovered the screw up. Before that, the truck had been running fine and was top notch. The engine has a 1981 date on the engine plate. Part # 11642105 Serial # 3930929 Kicking myself I didn't take a picture of the engine plate now.
My guess is the pistons slammed into the high oil level and ended up hydraulically (did I just make up a word??) blowing out the rings. I haven't done a leak down test or a compression test......I haven't tested anything. Just went up and wrote down the info off the engine plate. And it was definitely dripping oil out of the exhaust.
Any thoughts or insights would be greatly appreciated. Like updated or aftermarket (better replacements) for the piston rings. Or what should be updated/changed while I'm in there ..........assuming it is the rings.
Thank you in advance!!
