I real curious to see if this keeps working or if when the breathers plug up on the inside you end up with excess crankcase pressure and have gaskets start to leak.
I only say this because you guys are talking like the engine breaths in through those ports when actually it is blowing out the excess crankcase pressure so eventually oil and carbon should plug those filters.
Keep posted on how this works and how many miles you are putting on your bikes.

I've had these on my Electra Glide since day one. No troubles. Who is talking like they breathe IN?

You know those vents weren't put in there just to blow oil out. They actually vent the air as it expands due to heat and blow-by of the rings. Built up air pressure has to go somewhere.

If the oil level is correct and will never blow oil, what is the benefit of doing this over the stock method of routing it into the a/c? Seems to me the reason most people change the stock set-up is the fact that they do get oil residue...some worse than others I suppose. I opted to run a 3/8" hose down under the bike this go round with no filter of any kind.
