Cm2350 Turbo Help please

[GhostHauling]

Yeah I know it’s been a learning curve and it was the dead of the winner in West Virginia and I couldn’t find a shop to do the service I only have someone to do the service if the weather is bad and I have nowhere safe to do it, anyways I’m doing the best I can wheel truck has had the maintenance free filter since I got it and it just said blank on the crank case filter housing. Also I’m wondering if I should change the sea CAC hose because of the rust on the clamps and rings. I grew up being told don’t fix something that’s not broken but where’s my truck I am so often doing preventative maintenance.
