Hi everyone, seems that when I get up to speed, about 45+ and stay going that speed for a while my car starts to smoke, kind of like it's burning oil, but I don't believe it is. It smokes for a few seconds, then just all the sudden stops. All the smoke shoots out the exhaust also. Then about 10 minutes later, it does the same thing. Anyone know what this could be?

You don't say what kind of tranny but if its a automatic you should check the modulator valve, pull the vacuum line off and see if it is wet on the inside from tranny fluid. It could be sucking fluid at high vacuum during cruising. Also, you may want to check your oil galleys under the valve covers to make sure they are not clogged allowing oil to pool and get past the valve seals.
