I have now installed a fresh gasket and made sure everything is scrupulously
clean, all obstructions out of the way. Fitted the gasket fully to the dry
cover to make sure it did not try to escape. The leak was not slowed.
Probably due to not getting it torqued down “Just Enough”. Once the engine
cooled enough, I cleaned it up, once more, and gave the nuts a squeak more
pressure. That seems to have reduced the flow.
I may get to “extend” my oil change, as there is pretty near all new oil in the
crank case. Must have leaked out and replaced a few gallons over the past
number of days while driving.
