The ruling on the .045 shim thickness includes the oil seal if used.
The valve stem seal has no tech other than it's thickness combined into the max of .045 to obtain a min of .815 installed spring height..
In other words, the valve stem seal can be used or not used and is no longer a tech item unless used as a shim. Also the rubber inside it is a non tech item..
Note: A special thanks to the newly formed Steering Committee for there work on these current issues.
