You said in the last 45 day's 300 miles,,,,,,i also asked if any work had been done to the motor,,,,,may have a direct relationship to the smoking problem.
As it is,,,valve seals and guides usualy show signs of wear gradualy,,,,you would have noticed oil usage before this point if that were the case,,,so i dont think it's valve seal's,,,,,how about a missed shift??
Has the motor been revved to high,,,even for a second,,,before it started smoking??
If not,,,,you can start looking at crankcase ventilation,,,and bypassed vaccume at the intake manifold ( difficult to check ) but usualy manifold problems occur after overheating,,,or gasket replacement.

Did it happen over time,,,or all of a sudden??

Just gradually over the last 45 days or 300 miles


chevy 37 Might be a warped intake manifold lettiing the oil out throught the valley. Do you have dual exhaust and if so is the smoke coming from both pipes on start up when engine is cold and then lets up when engine warms up?

No sir, starts smoking right from the start, smokes about the same even after it's warmed up...
