Juz Posted March 2, 2009 Share Posted March 2, 2009 Hi All, Defender 200tdi After fitting my snorkel, I found that the system was not air tight as the hoses in the engine bay were rotten, so I've changed those. I've now found that the air filter housing has a dump valve (looks like a bird beak) that is letting in air. What have you guys done? A) Removed the dump valve and sealed the hole completely B) stuck a new dump valve on and found it seals pretty well C) nothing I do want to do some deep wading so I need to do something, it would help knowing what the consensus on here is.

Les Henson Posted March 2, 2009 Share Posted March 2, 2009 You could fit a new dump valve, but best be safe and blank it off. I think the top off a WD40 can fit's the hole perfectly. Les. Quote Link to comment Share on other sites More sharing options...
Mark Posted March 2, 2009 Share Posted March 2, 2009 I welded a plug into mine, and tapped it to take a hose fitting. This is then piped to a small tap under the bonnet. In normal operation the tap is open, and allows any water to run out. When out playing the tap is closed, sealing the airbox up again. hth Mark Quote Link to comment Share on other sites More sharing options...
freeagent Posted March 2, 2009 Share Posted March 2, 2009 I think a 2p coin goes in the hole nicely... then fill over the top with mastic... Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted March 2, 2009 Share Posted March 2, 2009 Remember there's also a matching drain valve on the lowest part of the inner-wing air ducting assembly. That is unless you've installed a snorkel that replaces this section. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted March 2, 2009 Share Posted March 2, 2009 Have a read of this http://forums.lr4x4.com/index.php?showtopic=4731 you need to do more than just the dump valve - if it's anything like the 300, your 200 airbox will be like a colander if you look closely enough A red WD40 cap is a perfect fit over the dump valve and also collects modest amounts of mud that get in through the snorkel Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted March 2, 2009 Share Posted March 2, 2009 failing that an old fashioned film container fits perfectly too! Quote Link to comment Share on other sites More sharing options...
BogMonster Posted March 2, 2009 Share Posted March 2, 2009 what's one of them? Haven't seen one for a long time now Quote Link to comment Share on other sites More sharing options...
Cat_J Posted March 2, 2009 Share Posted March 2, 2009 I used a WD40 lid. After installing my safari on my 200 I wished I had bought a 300tdi. Quote Link to comment Share on other sites More sharing options...
