If you ever cut open a PCV valve

That little stupid $3.50 valve cut vehicle smog emissions by half. At that rate for another $7.00 the only thing that should come out of the tail pipes is cotton candy and warm oxygen.
PS if it take your guy and hour to take apart 2 PCV valves you may need a faster mechanic.

And in 2 years you will need 2 scan tools for these emission control MARINE engines. You will need a OBD II scan tool plus the lastest greatest Diacom or CDS. Year models 2018 starts the EPA / OEM marine standardization and then for the outboards when they get CATS. Huge changes are coming soon.

So those are there for emissions? Interesting! I know my buddy's new Master Craft X55 has the 7.4 Ilmor,which has 540 hp and his engine has cats. I won't be buying a new boat anytime soon, so i guess all I need to worry about are my two PCV valves.

Yes, PCV's are for emissions, however, they also help greatly with getting humidity out of the oil.

So what exactly is the difference between running real pcvs to the intake and just hoses to the flame arrestor? I can see how pcvs have a strong vacuum actually sucking fumes out of the engine. What do the flame arrestor ones do? Just suck in what the engines push out? Doesn't seem like there's much sense to them.
