Air filter system sealing

[ThreePointFive]

Hi all,

I'm trying to finally get my snorkel plumbed in properly so that if I do something stupid in water I at least won't be hydraulicing the engine, even if I get no further. As the engine doesn't stall when a bag is put over the intake, I'm going through the joins in the system to make sure it can't draw air in from elsewhere. I have just taken out the air filter box expecting to find a small bung underneath that could be the source of where the air is getting in, but what I've found is a lot larger than what was described to me by others, so if someone can identify what it is and how to seal it up I'd be grateful.

I think the mystery of at least where part of the air is getting in is solved.

Use loctite 598 or similar sensor-safe silicone, my dad actually siliconed a ping-pong ball into the drain hole on his RR as it was the perfect size. You could also use a bit of bike inner-tube. Also check the seams on the filter, those things are not manufactured 100% water tight.

I opted for the bike inner tube and loctite instant gsaket (as that's what I had lying around). The rubber is a bit flexible but as the least resistance is obviously through the snorkel then I can't see it coming under much pressure. I do need to watch it when I test the system for leaks when it's put together though. In case anyone else is going to be doing it, here's mine:

BTW it is (or was) a rubber valve that did let water out but not let air in. In its current condition it serves no purpose!
