Blow by Vent leakage 07 Norge

Recommended Posts

I have an 07 Norge that I have been fighting the blow by vent leakage.http://www.harpermoto.com/cover-grey-976098.html   I have replaced the O ring (part 39) , the plastic housing, (part 18) http://www.harpermoto.com/raccordo-sfiato-blow-by-05007230.html  and the vent tube.  I am still  getting oil all over the the block from the leakage.  My next move is to use some The Right Stuff and make a silicon gasket.  Has anyone used The Right Stuff before, and if you have how did it work for you?? http://www.autozone.com/autozone/accessories/Permatex-4-oz-automatic-tube-the-Right-Stuff-gasket-maker/_/N-25y8?itemIdentifier=82550_0_0_

 

I am at wits end trying to gert this thing to stop leaking.  It is making a mess out of my bike to say the least. any helpful suggestions are welcome.

How's the mating surface? I'm not exactly sure where this vent is located, although I did view the Harper's diagram.....does it mate against true block itself?

Whenever I have had crankcase vent issues I always check the system for blockage. There should be zero pressure in the system to force oil out of the system.

A pinched line or a blockage somewhere might be causing pressure in a system that was not designed for pressure.

Other than that, I have used that product, it is just silicone RTV in a pressurized can that makes it easy to apply. It does what it is supposed to do.

Nah. It's just a piss-poor design. Had MG designed the part with a slightly larger flange and circle groove using a standard o-ring , it would've worked fine. Instead it has a serpentine design for the sealing ring guaranteed to never seal properly. Boeing used to use some stuff to seal aircraft wing tanks back in the '70's called "595" and for sure it would seal it - but you might never get the fitting off if you need to.
