So the dually blew the rear main out clear into the flywheel. Prior it would puke oil smoke out the exhaust and the main would dump oil under the truck on the exhaust too. Any time boost or RPMs were up there the truck would stink to hell and back and guzzle oil. I vented the crank better as a proof of concept and it worked, so I further refined it by routing the fumes into the intake. To do this I used a silicone port.
See that pretty AN fitting? Its corresponding 90 degree hose fitting ended up being too small, so today I grabbed some crap from Lowe's to make it play nice.
That's more fitting the theme of this truck. And the ghetto *ss port I mounted it to. The finished product is still cleaner than what it replaces.
Next step is to summon the motivation to remove lower intake, weld a bung to the oil filler neck, and permanently install that way. So looking like next winter because the truck works and it's race/camp season. I also changed the oil and cut open the filter since running it dry twice and found nothing more than a flake here and there, not sure how concerned I should be as I've got some hauling miles on it since the new rear main went in.
