I recently had a new rebuilt 350 engine installed in my 1980 camaro. At first, light smoke was coming from the bottom of the car, as well as from the tail-pipes. After they machanic found the problem(oil leak from the top [front] seal, he repaired That problem, but still, there's smoke coming from the tail-pipes as soon as I hit the 45-50 mph mark. I'm told that the smoke from the bottom will stop as is dries up or if I wash the underside of the vehical, but I haven't contacted him about the smoke coming from the tail-pipes yet( as I just picked it up late yesterday [11/30/07] ). Please, I don't have any knowledge of cars at all.I'm learning as I go with this [my very first]. Please tell me, from your experience, what is more than likely my problem? I'd so appreciate it. I thank-you in advance as I await your response.

First of all, if this motor is a freashly rebuilt motor it must be properly broken in. White smoke may be caused from the rings not being seated yet or something like that. You shouldn't drive at speeds over 55 mph for at least 500 to 1000 miles. And you should not drive at one constant speed. Varying your speed will properly seat your rings. After the break in period you should change the oil and filter. If the engine is still smoking then you may have a problem. However make the engine builder aware of your consern asap to avoid any warranty issue problems down the line. Just keep in mind that there is a break in period for a new re-built motor.
