OK, '85 EA82 carb. with 280,000 on it. This has happened twice now in the span of 2 months. I am going down the road, everything is looking fine on the gauges, and then out of no where it will start to blow oil smoke out the exhaust pipe. Enough smoke that I thought I might have blown a head gasket. The smoke persists for about 1/2 mile (through gear changes and such) and then just as quick, it stops completely. No change in the way the car runs at all, before during or after, no change in the gauges:confused:
Any ideas on what it could be?
