Okay, I pulled the remainder of the intake valve seals and the rest seem much better for fit on the valve stem. Definitely a fair amount of difference in the level of deposits on the intake valves. Some valves have a relatively thin even coating where others have a relatively thick, almost chunky appearance to the deposits. There is not a great correlation between the valve deposits and the spark plug deposits but similar trends. It is hard to tell if the thin even layer of deposits is from oil or from fuel.
Valve to guide clearance seems to be 0.005 or less on all the intake valves with most not having any real feeling of clearance when trying to flex the valve stem side to side in the guide, the first valve removed feels to have the most clearance and is the one with the seal that seems loose on the valve stem. The measurement of 0.005 I am getting is above the keeper grooves so more movement than if it was at the top of the guide.
I'm feeling less confident that the stems seals were the major source of the oil consumption but there was clearly oil from some source going through the intake tract resulting in the deposits on some if not all the valves.
I have pretty much run out of time to work on this until after Thanksgiving due to other plans.
