My 1989 Mazda Rx7 is smoking like hell. Like it cranks up and runs fine but it lets out whit smoke repeatedly and wont stop. i let it run because it hasnt been ran in a while so i thought it was all the build up. What could this be, i have no idea. Thanks alot

 

Turbo or non turbo?

White sweet smelling smoke is coolant, which means a bad coolant seal.

Black smoke is too rich.

Blue is oil.

 

non-turbo

where is the coolant seal?

 

its burning oil through the exhaust.

what could this be?
And how do you fix it?

 

It is inside your engine. You'll have to pull the engine apart to fix it,if that ends up being the problem.
