Lightbulb Good tip for airbox seal

Most people who have snorkels fitted will have also used sikaflex or similar to seal up the rest of the intake to prevent water ingress. I also have gone at it with the old sika and thought every thing was nice and water tight...until I spotted mud stains on the air filter element. I had a good look around and decided that it was the pre-cleaner unloader. It's basically a one way valve that lets all the heavy particles trapped in the pre-cleaner fall out, while preventing air from getting in. It was shagged and had let water in. So away with that, but how to seal the big hole?

After grabbing measurements and a bit of searching around I bought Trailer Bearing Protector Caps from supercheap auto for $10 and with a little heat to soften one up, slipped it on (I had to use a flat blade screwdriver to help). I finished it off with a worm drive hose clamp.

The benefit is that I can remove it later to check for those heavy particles (usually small rocks get trapped in there).
Here's a drawing of the pre-cleaner and the original valve at the bottom.

If it's the part I'm thinking of, the snorkel installs on my cars have both removed that little box inside the guard...

Safari snorkel on the NL Escape.
TJM snorkel on the NL Shorty.

Interested to know the difference....

Hi Alex. You're thinking of a different part. The pre-cleaner is the drum looking part which leads into the airbox. Inside it are fins that create a cyclonic effect on the incoming air, which forces heavy particles to the outer edges.

Yep that's the one, it's inside the guard on the NLs. Both installations in my cars have removed that box...

Presumably you've got a different model of Gen2 and/or snorkel brand?

After a little research it is clear that this fix is only necessary on the 3.0L v6 models.
