Air box oil

[dvmdf]

Happy Thanksgiving everyone. I just wanted to get a feedback on the oil in the airbox situation. I have a 2008 RS SE5 and I've had this problem after about 2000 miles on the bike, As far as I know- no real fix from BRP. I've used catch cans, but they leak eventually and oil drips on the exhaust pipe producing a nice smoke, I keep my oil level low, now I am trying foam in the vent hose. What do most people do? How often do we change the foam, did anyone have an issue with the foam getting sucked into the throttle bodies?
You feed back is appreciated.
I love my spyder. Riding never stops in SoCal.

The foam won't get sucked into the throttle bodies if it fits well in the hose and is behind the nipple on the airbox. The nipple keeps it in place against the small amount of suction or pressure. Unless the intake snorkels or air filter got badly plugged, the suction at the hose would never be enough to compress the foam and pull it into the airstream. If things were that plugged, the Spyder wouldn't run anyway.

PCV

go to your nearest auto parts store... ask them for a PCV (Positive Crankcase Ventilation)... and splice it into your 3/8" rubber hose that connects the air-box to the crankcase... should cure your ills... it did mine...

I am not sure this is a good idea. It will solve your oil in the air box issue but I'm thinking it could also create a new problem.

A PCV valve allows air to move in only one direction. The vent system on a Spyder is designed to allow air to move in both directions so that both positive and negative pressures in the crankcase are relieved.

The PCV valve (by design) is going to prevent pressure releaf in one direction or the other (depending on how you orient it in the vent hose). So you're going to have unrelieved pressure in your crankcase. If this was OK I think BRP would have installed a PVC valve at the factory.

My feeling is you're much better off maintaining a 2 way vent system (as designed) with something to prevent the oil from passing on to the air box. A properly sized piece of coarse, open cell foam designed to be saturated in oil is the easiest way to accomplish this.

Once this is accomplished you can then run your oil level where it is supposed to be. Some oils foam a lot. If the oil you are using has a lot of foam then I highly suggest changing to a non-foaming lubricant.

i've had mine in for over 10,000 miles nows with no issues... i'll have to check it and see... thanx for the info... always good to hear the other side...

Ours is a 2011 SE5 and I'm getting oil leakage through the weep hole in the main frame on my garage floor. My understanding is that there's a air chamber that's open that allows the oil to filter in. That has been fixed with the 2012's. There is a fix for it, but it has to be done at a certain time. I'm guessing by the previous post, that it's during the valve adj.

OK OK

:agree:

OK, OK.... i'm beat'n up... :gaah: how 'bout i pull the PCV and replace it with a small, marine type, gas filter... the ones you can buy at Walmarts with the glass blub so that you can see what's happening inside... (hmmmmmm, never had a problem with the PCV valve.... just say'n)....

Sorry, not trying to beat you up. We all want to put out good information to our fellow Spyderlovers and that's exactly what you intended to do.

Some ideas are simply a matter of preference. I like highway pegs, you might prefer floorboards. No big deal.

Other things are just a bad idea for reasons that one individual may not have thought of. Something may seem to work (and may work) for awhile with unseen issues developing. My feeling is that anyone who posts an idea intending to help others (including me) has run into a dead end from time to time.

This is the beauty of a forum where different perspectives can take a look at an idea and 'vette' (not vent), if you will, the concept.

If an idea can withstand reasonable argument then it's probably a good approach. No one is perfect and we all come up with flawed ideas at times. No shame or reason to beat someone up over it. The end result is what all of us are looking for, a better mouse trap. Ideas that don't work are just part of the process.

If you thought this up, some other Spyderlover may also think of it. This discussion may help a number of owners.

The alternative is for everyone to quit thinking up new and possibly better ways of doing things, and no one wants that.

In the end, it's all good! :thumbup:

For some reason this is my favoite option!
