I have an 83 K5 and smoke comes through the vents. When I'm idling it's fine but once I get rolling it comes in pretty bad. I'm a mechanical novice so any suggestions would be appreciated. I was having some blowby issues but that's gotten under control and it's not that bad anymore. Also, white smoke coming from driver side tail pipe. This is my daily driver and I need help.

 

maybe a leaky valve cover or something leaking on the back passenger side of the engine and getting sucked in by the air intake for the blower motor.

 

also - white smoke out of the tail pipe sounds like a bad head gasket and or intake gasket and your burning anti freeze

 

I apparently made a rookie move and changed out only the driver side gasket. I'll change out the other one today. A buddy of mine said I should have a hose going from my oil breather to my air filter. Any comment on that?

 

Odat, my levels are full and there's no milky look to oil or antifreeze so I'm hoping it's not the head gasket. I know it doesn't mean anything but the top end was rebuilt two years ago. I might be in head gasket denial.
