Less emissions sounds okay to me. I realize it will get less mileage, but it's nice to not have black smoke and put out that weird stuff into the air. Do you guys still recommend removing it?
To answer questions: The bus is a Washington State bus. @PNW_Steve it may be familiar to you.
I believe what you are looking at there is a crankcase filter system. Not really something that needs to come off. I see that there is a filter number right on the canister.
This system captures all of the vapors from the crankcase and runs through a filter so the oil doesn't drip on the ground.
Here is some information
Should be a simple job to swap out the filter.
I'll see if I can find some more information.
