Made a quick vid while working on the car today. I got rid of the factory shorty vent tube that only goes a few inches off the reserve and added a 5ft hose.

Smell has been greatly reduced but is still evident when the car first hits operating temp. Might be residual in the HVAC system, should know for sure in the next week or so. If it doesn't work as planned i'll post that up also.

I might have to add some tape or something over the part of the duct that draws air from the engine bay, and add some sealant to prevent the duct and molding from allowing air in.

Cheers,

Hoon

Still getting a mild smell when it hits operating temp, but overall its much improved

No it wasn't cold, probably 150* when i started the video, but it shouldn't matter whether it's still warm as long as everything is clean/dry

Thanks for the instructional video. I'm not taking it to the dealer until something is proven to be more effective, but your video will let me do it myself. Did you have the dealer do the tape job first? Did they do any sealing of the vent area? I think I saw on another thread someone had posted pictures of the sealing, too.

Also, where did you connect the other two zip ties? I saw the last one.

This definitely helps but it is not a complete cure. I think vapor is exiting the cap also. My theory is the o-rings compress over time and allow blow-by out of the cap itself, and mine has dried residue and liquid after the upper seal which lead me to that conclusion.

I didn't bother pressing the issue with the dealer. They were useless.

I connected one zip tie to the wiring near the tank and the other to a line above the transmission to keep the hose out of way of the shifter linkage.
