Hole in the bottom of TDV6 air box, normal?

[kelvo]

While having a poke about in my new to me MY14 TDV6 I noticed a hole in the bottom of the air filter box, see red circle hole in photo. This is in one of the two fixing points to the body. In the upper section there is a rubber one way valve type assembly, which makes sense. But no valve assembly on the lower hole. While I can sort of see why there would be a drain hole the lack of one way vale seems odd.

So the real question is, is this normal?

The rubber plug has probably pulled thru and still attached to the inner guard.

I replaced my filter yesterday and yes, I have the same hole that goes through the bung that secures it to the body. I thought the same. I also questioned the value of my snorkel with a hole in my air box. At the moment I’m in deep thought, before I sikaflex it up. I like that it acts as a drain, but I dislike that it acts as a potential entrance.

The rubber bung that it pushes into is open at the bottom as well.

I’m glad that it’s not just mine, but still puzzled why it’s wide open.

Mmmm. Must admit I've never noticed a bung and I've changed or cleaned my filter a few times....... so tomorrow I'll check mine as although I have a Safari snorkel I don't want water coming up through the bottom. Not that I intend doing and deep water wading any time soon but one never knows.

I was going to silaflex up the hole in my air box too, as the original rubber one way valve had perished. Then I decided there must be a good reason for the hole, so with a couple of stainless washers, a stainless nut and nylok, plus a flexible rubber washer cut to size, I made a new one way drain valve. I also have the Safari RAI, I have found water at the bottom of the air box after driving in heavy rain so I wanted to be sure it can drain out.

Wonder if there's a one way drain valve available that would fit that hole, would be perfect. I didn't notice it there when I changed filters either so assuming the bung is still in place.
Haha, I must have skipped over Eric's post. Nice idea Eric. I wanted to fit one to the original spare wheel winder hole, so I could put a water tank above it.

I read somewhere in a snorkel installation manual - or was it on a you-tube install video - that the hole is to be filled - I think they like to totally seal the airbox to achieve submersion success??

My safari instructions didn’t include that I don’t believe.
