Oil and filter

[Searcher_imp]

Just to add a little info on the washer, since you guys have helped me in the past, when you crush the washer you have stressed it past the yield point into the plastic stress range. Not only was it permanently deformed but there is a residual stress in the washer material when you remove the oil plug. Bolts are routinely tightened into the plastic range in construction but they are not supposed to be reused. Of course there we are talking about critical fasteners on steel structures and we are only talking about crush washers here that are easy to see if they leak. But everything that effects my CB1100 is critical to me!
