honitonhobbit Posted June 29, 2007 Share Posted June 29, 2007 I am nearing the end of my little snorkel project and was pondering the following When water gets in the intake of the snorkel via rain/drizzle/JST, what happens if the flapper bung on the air box is sealed? Why seal the bung? I have no intention of deep water wading a'la the ruffty tuffty hardassed 4x4 guys and girls. The only reason I have built this snorkel is due to near misses when wading 'lanes and such. The bung has been sealed for ages though simply because that is the way it was. No worries when the intake was at the back of the engine bay. So back to my ramblings (bit overtired at the moment). What should I do, unseal or ?

bishbosh Posted June 29, 2007 Share Posted June 29, 2007 I would hazard a guess that the volume of water that gets in to the snorkel via rain and drizzle is small enough to vapourise as it moves thorugh the intake system and wont cause hydraulicking issues. JST interventions however will require a totally different approach..... Quote Link to comment Share on other sites More sharing options...
Les Brock Posted June 29, 2007 Share Posted June 29, 2007 Leave the drain blocked, small quataties of water will disipate through the air filter, if you do un-block it, defeats the object really, as water splashing around will find its way in there ..somehow Quote Link to comment Share on other sites More sharing options...
white90 Posted June 29, 2007 Share Posted June 29, 2007 I go further to say I'd remove the drain altogether and have one tube from snorkel base to airbox. Mine has bee this way for a couple of years. never had any water/condensation in the airbox. The drain is always a weak point if the sealing were to fail.

simonr Posted June 29, 2007 Share Posted June 29, 2007 On my 110, I blocked up the drain - and when I came to change the filter there was a dessicated dead bird in there! So just think on! Si Quote Link to comment Share on other sites More sharing options...
Les Brock Posted June 29, 2007 Share Posted June 29, 2007 Still the air filter did it's job Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 29, 2007 Share Posted June 29, 2007 My dad blocked his up and hasn't had any problem, but then his snorkel is the super-deluxe ultra-extreme B&Q version Shaun didn't block his up: Quote Link to comment Share on other sites More sharing options...
ThreeSheds Posted June 29, 2007 Share Posted June 29, 2007 Shaun didn't block his up: A picture is worth a thousand words... Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 29, 2007 Share Posted June 29, 2007 He was sat, stuck, in a puddle assuming that his nice snorkel was doing it's job and then the engine stopped... as you can see, it was proper bent, and the others weren't much better.

landrover598 Posted June 29, 2007 Share Posted June 29, 2007 Results of another unsealed drain plug I've welded over my drain plug, may get to test it out next weekend juging by the amount of rain we've had/forecast Where are the pics of said snorkel Dave ?

JST Posted June 29, 2007 Share Posted June 29, 2007 i would leave it sealed, i am assuming yours is in the end of the air filter box, same as mine which makes it more of a bugger to seal rather than the separate 300tdi setup where you can removed the drain section from the pipe as Tony mentions. it may be of interest but in the end i sealed mine with a bit of inner tube held on with cable ties around the external of the drain, after removing the ducks a**e. then added some silicon sealent inside. and to date its worked fine.

It's on the end that unscrews to refit the filter and at the moment it's blocked with a pipe bung sealed with sicoflex and oversealed with external grade clear silicon - oh and it's pointing upwards... Dave, pictures will be forthcoming when I take some and it's fully assembled. Another question: Option one - periscope type snorkel top - with option to face front or rear Option two - canted pipe work back over the roof...

white90 Posted June 29, 2007 Share Posted June 29, 2007 David does yours have the water trap part number 10 in the pic, along with totally sealing item 3 and the airbox (the factory pressings leak to tech archive has more on this bit) this is what I removed along with all associated connections. PS for everyone else if you cover the snorkel and the engine does not stall that air getting in to keep it running could easily be water.

honitonhobbit Posted June 29, 2007 Author Share Posted June 29, 2007 Tony, As it is a 200Tdi Disco lump attached to a defender box, it only uses the 300Tdi air box - the pipe work is all unique so the flapper bung I was refering to is part 3 - great diagram by the way. The intake is now under the outer wing skin top exiting through a plate on the wing top a'la Mantec V8 snorkel style. There isn't room to run it through the wing up by the bulkhead...

I went for option one, and facing back because there are lots of very tight greenlanes around here, so wanted to keep as low profile as possible Quote Link to comment Share on other sites More sharing options...
