I have a 1992 Mazda 929. I noticed that a lot of smoke comes out when the car is just starting to pick up speed but smoke stops coming out when its already running fast. What could be the problem?

Sounds like valve seals but try changing the PCV valve and see what happens to the smoke-I've been here before 323/626

Do you see the smoke a lot while decelerating if so remove spark plugs and read it. Wet with oil means the combustion chamber is leaking. You can do a compression and leak down test to id the problem

Do you consume a quart of oil less than 500 miles-

Yah try changing the PCV valve. If you have a 3.0L sohc engine in it, you might have a leaking valve seal (s). Its not uncommon with the older 3.0L to do this.
