Hi I'm Wayne

I will help you with this

There is a replaceable valve stem seal on the intake valves of your engine. This is very possibly the source of your aggravation. This is not an uncommon condition with overhead valve engines and since the smoking is not excessive it's up to you if you want to replace the seal
