Alright when I start my car(1990 accord ex) up after sitting over night it will smoke(white smoke) from the exhaust for about a minute or so. I had the head redone after the timing belt broke about a year ago and this problem started right after that. I use a quart of oil about every 500 miles or so. Is this because my valves are not seatting properly or is it because the lower half of my engine is older then the top half. ie the top has more pressure then the bottom and oil is blowing by the rings. This is what the dealer is saying and won't take any ownership to the problem. My car has 152,000 now but 125,000 when the this all started. Any help would be great.

One, when I start the car when it has sat for a long time the amount of smoke is excessive. It does not smoke when after it has been running that I have noticed. I have not done a compression test yet, I will be soon though because I want to change my plugs. Will the compression test definatively tell me if the trouble lays with the top or bottom halve of the motor?
