In response to iRiE

Any vapor or smoke that comes out of the breather tube you mention is actually the amount of blow by that is going past the rings. Normally the more blow by you have means the rings are getting bad. In other words the motor needs rebuilding. Excessive blow by means the motor is getting tired.
One thing I try is run it to 60-70 mph, let off the gas and coast until you to to about 40-50 mph then step on the gas and watch the exhaust pipe, and see if puffs a cloud of smoke. Just my 2 cents.
