agexpert, the 14x4w is a great choice for you with the 82

and modeone, you are right about the vents primary mission being a crankcase breather, but were back to killing two birds with one stone, because it also allows oil into the case on the power stroke with blowby, this is where the positive flow out starts thereby oiling the innards.

the length of the tubing out needs to be 4 inches because if any shorter it will suck in outside air(with dirt) back into the case on upstroke because the vacum amount equals the hose capacity at about 3 inches.

hope this makes sense to you[&:]
