Doing my spring maintainence, & one of the issues I'm dealing with is oil sneaking out from under the oil filter cover(that sneaky Mobil 1). I noticed last time I installed an oil filter, that my G5 differed from the manual, in that it has an upgraded filter cover, with a bolt & a spring loaded copper washer protruding from the inside (looks like the pricey one from Hitchcocks) So I'm guessing some of the internal O rings in the manual arent necessary?
Anyway I re-installed it yesterday. After cleaning the covers mating surfaces, I put it back using silicon form a gasket, instead of the leaky paper gasket. I was very carefull not to over tighten the bolts, which I replaced with some pretty stainless allen heads.
I'll let everone know how this works out.
