I installed a catch can on my 2001 X1 and now that I have been riding it for awhile I have notice a few things that I am not sure is normal or not. When I come to a stop there is a strong oil/chemical odor coming from the catch can. I can also see steam/mist or something similar coming from the filter of the catch can. I have installed xb rocker covers and have them venting to the catch can as well as the crankcase. Here is a pic of my setup.  | ||

Elaborate on this. A little blowby is to be expected. I've always encountered more at extended high rpm use. If it's excessive there may be a bit of leakage past the piston rings. If compression is good I wouldn't worry about. If it's low there's a problem. | ||

don't worry it's totally normal. | ||

It should have read I have installed xb rocker covers and have them and the crankcase venting to a catch can. | ||

I'm using two catch cans myself and moved them under the seat as those fumes kill me at a stop. Is your transmission vent going to a catch can, too, then? That usually won't leak fluid unless over-filled. | ||

I'm new at this, but I thought the rocker box cover vents are the crankcase venting..? And the transmission vent makes the third hose. On my bike this is a long tube that routes to an open-air exit near the license plate. My catch-bottle has about an inch of 'stuff' in it, but no smell, even when close to the filter. | ||

When I come to a stop there is a strong oil/chemical odor coming from the catch can. I can also see steam/mist or something similar coming from the filter of the catch can. I have the same catch can as you (apparently) but mounted it fairly horizontal on the left side on my S1. I do notice an 'oily' smell but no so strong as to make me nauseous, just noticeable standing still. I have nothing to pour/drain out after a couple of oil changes, just had to shake it up to get out on the garage floor a couple drops of oily water. So I left it mounted fairly horizontal as is. But there is a sort of whistling from the can that is noticeable at idle, especially after sitting overnight, before fully warmed up. Not noticeable from the right, but if I move my head to the left side, I hear it. Just a whistling that is quite 'un-Harley'. | ||

I think that catch can is mounted too high. I would personally mount the can as low as possible in the frame. Mine is near the oil filter and I have had no issues for the past 15K miles. YMMV. | ||

run a hose from the breather nipple to the rear of the bike and but the breather there! | ||

The most important breather hose to connect to a catch container is the TRANSMISSION BREATHER HOSE !!! If you get oil on your rear tire you will better understand !!! | ||

I hang my catch can on the left side along side the oil lines. My trans vent hose connects besides the XB rocker pcv hoses. The breather is under the tail light. | ||

Why would it matter how high I mount the catch can? Is the crankcase vent the same thing as the transmission vent? The smell is not so horrible that it makes me sick. I can only smell it when I am at a stop. I don't smell anything when riding. I also do not hear any whistling noise coming from it. | ||

They aren't really pressurized lines, so therefore if you route it higher than the vents, the oil will just stay in the lines and the breathers won't be able to do what they are supposed to do...breathe. Gravity, it is what keeps your wheels on the ground too!  | ||

I have the XB rocker covers so the engine breathers are now on top rather than coming out the side near the air cleaner. The transmission vent is the only one that is below the catch can. I may look at moving it on the bike. |
