			Worn exhaust valve guides commonly lead to blown stem seals.  Have you had a leakdown/comp test performed on the motor?

			No i did not. I was hoping it was just a valve stem that is gone. If this seems to be either valve guide or stems then i think i`ll try changing the valve stem without taking out the engine as i have very limited space and hope that fixes it for now.
