Thread: Hole in the bottom of TDV6 air box, normal?

Hi All - apologies for the thread resurrection. I have just come across the issue myself where the bottom hole of the airbox has a rubber flap that has all but disintegrated. Is there any update to whether people have just plugged the hole or managed to get a replacement part to act as a valve? Is there an agreed "best practice" ?

Also worth mentioning is that I do have a Safari snorkel so am mindful of any rain water that may get in.

Cheers.

I siliconed the lower hole in the air box up about 100,000km ago

That's good to know, especially being for an extended period of time. Do you have a snorkel on your vehicle?

Yep, safari snorkel

The valve if working correctly allows water out of the first chamber of the airbox but stops it coming in - even with a snorkle I guess there is always a chance water can get in and if there is no way for it to drain it will build up.

I would be looking to reinstall the valve and making sure it works.

Thanks for your input. My preferred option would be to replace the valve too but I can't seem to find any replacement part? I don't want to have to buy a new air box just for the valve either.
At the moment the silicone option is sounding like the easiest, if not preferred. If I fully plug the hole I guess I will have to check for water in airbox regularly.
Cheers.

I change air filters every second service (so every 20,000km) I have never found any trace of water in the airbox (daily driver all year round) and I never check in between services. I do find insects or bits thereof in the second part, and usually vac out the whole thing before a new filter goes in. At this time I also clean MAF and MAP sensors (gently, with sensor cleaner and not with compressed air).

I get the idea of the non return valve allowing water to drain out of the airbox, but to me this defeats the purpose of having the snorkel fitted, the whole point being to raise the air intake to roof line so that you can potentially wade through water up to bonnet depth. This is why I sealed mine.

The raised air intake is designed to she water that enters the head. There are gaps in the head that the incoming water will drain out. The inlet pipe is above these channels. Unless you bought a cheap Chinese one like for a D2 Then you have to add these channels.
