So, I'm going down the road pretty much flat out in 4th or 5th, engine WFO under full load at 3500 to 4k, when suddenly the engine goes flat and a huge oil cloud bursts fourth from the exhaust. "Oh spoob", I'm thinking, "holed a piston, or sucked a valve" In just that amount of time, it quits smoking and the engine regains power, and I'm off.
This happens once about every 2 months, sucks a big glop of oil, spits it out, keeps on going. WTF? Anybody ever heard of this? How can the engine suddenly suck in a bunch of oil all in a lump, then not do it again for a couple of months?
