Im starting to wonder if you are able to say something without being completely condescending.
It's only seems condescending if you think you know what you are talking about but really don't.
So ok then, I'll be direct. You are talking out your ass, with only conjecture to back it up. No data, No facts, just opinion, and your own feeble rationalization.
(Is that better? I would think not, but maybe that's better than perceived condescension.)
At any rate, I think of it akin to second-hand smoke, in that the base content might be slightly worse (assuming, of course, youre using a filter there and not a catch can to collect oil vapor), but the overall amounts are so much lower than that coming from the exhaust that the harm done in the end is much, much lower.
You are rationalizing, not analyzing. You are also wrong. Have you done no research about crankcase ventilation devices? This device began implementation in the 60's and is still put on production machines to this day. Do you really believe such a device would have remained in vehicles for this long if it wasn't a significant asset? Are you afraid to research because you fear the outcome won't support you position?
On a side note, how can you say the blow-by gasses havent been subject to oxidation?
I'll give you the benefit of the doubt that you really do want to know. Here is the explanation I really hope you will find valuable.
It is due to the nature of combustion within the cylinder, and the flame front travel. Combustion begins at the spark plug and the flame front travels out ward from there as the cylinder pressure builds. That portion of the charge nearest piston edge and closest to the cylinder wall gets high pressure well before the mixture there can begin to combust. In fact, this pressure is often relied on to help put pressure on the rings toward the cylinder. (research a Dykes ring which takes full advantage of cylinder pressure to provide a combustion seal.) Combustion does not take place on the cylinder walls during the combustion stroke as the temp there is too cold to support it. (You really don't want the cylinder walls to be at 1500F anyway, as any film of oil there would would cease to be of value.) Further, the ring seal process is not instantaneous, and the unburned fuel charge in the corner of the chamber where piston meets cylinder wall seeps past the rings into the crankcase. As the engine ages and the ring seal get worse (Piston groove wear, ring face wear, and cylinder wall wear), so does the amount of unburnt blowby combustion chamber gasses, that never have the chance to get burned.
The hydrocarbons there came from the combustion chamber, and unless you have such low compression that the bike wouldnt run, would have had to have been subjected to the ignition, same as the exhaust. Whats more, they would be influenced by the AFR's as well. A ratio is a ratio, before or after combustion.
See above why this rationalization is in fact fiction.
But thanks for the advice. Ill go ahead run my bike sans baffles and breather tube because I hate the Earth.
That's is the most sense you've made thus far, and explains a quite a lot about your arguments/position. I can only assume youth is to blame.
