I pull the intake valve
Mark with Sharpie and gently lap to check the contact pattern
To my untrained eye they look pretty good..??
Clean, oil and re-install valve and re-check with alcohol. Still seeping past the INTAKE valve slightly. EXHAUST side is dry as a bone.
Here's where it gets weird... I reinstalled the head, torqued and checked leak down. Now LD is 7% (down from 12%), I cant hear ANY air escaping past the INTAKE valve but can clearly hear air going past the EXHAUST valve. WTF??
Does torquing down the head load the seats in a way that the seating can change?
Am I just chasing my tail here and should just put it back together and enjoy??
