okay boys i have an update. ...
went for a nice long drive yesterday and when i got out of car i knew it wasnt fixed immediately all 911 drivers know that smell.
so i jacked up the passenger side today and got under, took off the cover and started examining. All looked bone dry the mirror i was using was a little big and couldnt quite get all the angles.. so i went for my dental mirror and flashlight
..... and sure enough there it was ... a very small but telling pool of oil at the base of the head of the bolt for number 6 ( way to go Walt )
it would have been easy to miss but it was definitely there. .. now this is where it gets interesting.
got my shortened 8mm in place beside the oil cooler and it got the bolt off with a little patience.. bolt came and collars came out, rocker moved easily, and is always a relief.
went to slide rocker out and it stops dead at the edge of the housing .wtf ?
tried a few times and stops dead. go in the house wash my hands ..and vo back in and i feel the tiniest of burs on the housing.. i allmost thought i was imaging it . sure enough it was there got some very fine emery paper and smoothed it out . cleaned it up and shaft pops out.
once out i did a much closer inspection.
rough area of corrosion on the outer edge of the shaft i never saw initially.. piece of the rsr seal missing where i must have caught the burr seen easily with a magnifying glass
as i didnt have another shaft i was able to buff the edge with my buffing wheel i must admit i did put a tiny bead of yamabond with a toothpick around the rsr seal as i did not have another before sliding it into place. cant even see it.
so we have a few suspects whether it be the cut seal, the rough edge on the shaft or a combination
the location i saw the oil trickle (rear side of head on cylinder 6 as in earlier photo) lines up perfectly with the problem i saw so here is hoping.
if i was to do the rebuild again i would use new rocker shafts without question they are not expensive and can prevent headaches.
i still might go back in and replace them all next spring
i will report back
thanks for all the support so far.
