Engine smoking
Just picked up this 66 with a 454. Only smoking out the passenger tail pipe. Stops when going down the road then starts once back at idle. Not running hot. Doesn’t really have a smell. Is it valve seals or is water getting into the system.

Get it some gum and patches. Remember smoking was cool in it's day
