I seem to be seeing a very little smoke, car hot,free revving the motor up about 5500-6000, does not smoke while under throttle but when the motor is just about back to idle it smoke blue alittle. Now im plannig on doing a roller rocker upgrade, do you think its valve stem seals? or is it alittle more serious? car has 122000 frist time its smoked

 

I'm assuming the smoke is coming from the exhaust?

 

yes
