Breather hose question.

[mopar19]

Hey all,
81 gs850gl.
I have a question regarding the breather hose that goes from the valve cover to the airbox. I removed the airbox and replaced it with 4 pods. My question is, where do I put the breather hose that used to attach to the airbox? I'm getting some smoke out of the breather hose. Is that normal?
Thanks for any info.

it is normal to get some smoke, at least for me. K&N sells a crankcase breather filter and you should get one of sorts as it prevents dirt and debris from contaminating the oil.

I got a longer hose and just run it down in the area in front of the battery box and behind the engine on my 1100.

I see the crankcase breather filters on ebay for cheap all the time but don't use one my self.

I purchased a breather off of ebay. Thanks for the responses.

I Went to Napa and got a 7/16 piece of hose with a 90 degree molded end,trimmed to correct length,then added a nice little chrome filter to match the k&n's from Advance auto in the tuner car section.Made a bracket to attach to valve cover bolt,where it now sits just above right knee, looks pretty cool to me anyway . And yes I occasionally get a little whisp of white smoke which I think is just a little condensation? evaporating out of crankcase. Good luck !!:-D

Doesn't that risk spitting oil out in the path of the rear tyre?

There should only be the occasional wisp of vapour coming from the hose.
If you do have oil spitting out the tube, getting it on the tyre will be the least of your immediate concerns. :shock:

Many years ago, before the Positive Crankcase Ventilation (PCV) system was implemented, cars and trucks had a tube attached to the valve cover or oil filler cap, that then was routed back and down, so the vacuum caused by the moving vehicle would extract the vapours from the crankcase. The tree huggers decided that was not very friendly to the environment, so the PCV system was developed. A couple of things in their favour, though, were that the breather tube was not in line with either of the rear tyres, and they had the stability of more than two tyres.

I use a K&N and have it bolted down where the airbox was.
