If the engine is out of time would that make the engine smoke and burn oil?

 

Have you recently changed the timing?

 

no i haven't but it has always burned and smoked and knocks at start up. but runs great

 

It could be a number of things, we need more info to help though. Edit your signature so we know what truck your talking about (year, size, trans.). If the truck runs well otherwise, it's probably not the timing. Is there a reason why you think it could be the timing? What is it set at now? Does the engine only burn oil on start up, or also as your driving?

 

If it only smokes after you start the engine that's usually leakage through the valve seals. If it smokes all the time (blue smoke), it's usually the rings, or the cylinder is just worn too much. Black smoke usually means too rich mixture.

 

Just at start up, or just dont notice it after its running. 1983 302 C6. Pictures finally up in Gallery.

 

If its just at start-up and its the tell-tale "blue" of burning oil, its most likely gonna be valve seals.
