I would pull the #4 cap off and measure the gap directly with a feeler gauge.
The #4 cap comes off with little or no fuss (as compared with the #1). If
you think the gap is a bit wide (say greater than .015) you can order up some
new thrust washers and pop them in. I bought a set of STD and a set of +.005
and used one of each to achieve a gap of about .003. Len Renkenberger suggests
that going tighter than the factory spec of .005 is just fine, in fact,
preferred. 5 years later, no worries.
