snorkel test?

Put a seal of some sort (NOT your hand) over the open tube (remove ram first). You should feel incredible suction. If the seal is good enough - you'll kill the engine.

Stick a plastic bag over it while the engine is running. If there are any air leaks in the snorkel you should hear air being sucked into them before the engine stops.

S&N asked for information on snorkel test
hi
When you do a dusty trip have a look at youair filter if it has more dust and leaves plus moths than you had before then your Snokel is not dust tight

could you cover the end so no air gets in and see what happens, if you hear hissing or it doesn't stall it would suggest sumpthing. thats just a guess as i don't have a snorkel to test for myself

Place the mouth piece in your mouth and submerge your head in water (bath, pool or any open water area). Then place your thumb over the top hole/end/opening of the snorkel and breath in. If any water enters your mouth your snorkel is stuffed. You may be able to repair the snorkel with silicon rubber or silly's no more leaks/gaps. I have personally tried this method in the past and it never fails, good luck with it and I hope my advice helps.

I tried the plastic bag trick when I first put the snorkel on and I must let everyone know it goes off with a very loud bang just before the engine stops.

Frightened the S**T out of me, well almost anyway.

Someone once told me that if you block half the inlet and spray some Aerostart or Start-ya-bastard around the joins, if there is a leak it will suck in through any gaps and change the idle speed of the engine.

What's up with the snorkel test???? - are you just checking up on the crazie workmanship while he is away ;-)

drive into a river over the bonnet, stop in the middle, wait for rod to come through side of the donk... send ads the bill.

Hows the missus doing with the bub? Have to catch up for beer soon.

well, our patrol failed the plastic bag test!!! i think the problem might be with the primary air filter box (the one behind the passenger headlight). it has a drain hole at the bottom of it, so i silliconed it up! Will see how that goes tomorrow, then will work back from there!

Levuka 4x4 park at Easter , at the mud pit , there are 2 pits side by side ,1 = upto 30 odd inches of mud ,fun and games ,,next to same pit is pit no2 that no one has gone into all w/end , Nissan Navara diesel "Ive got a snorkel ,Ive got front and rear diff locks" into the pit ,, mud above headlights ,water 18inches above that ,, snorkel FAILED to be air tight .,,, umpteen tries for snatch out ,one totally furbar Nissan motor ,,, !!!!!! "Ive got a snorkel " Better be bloody airtight !!!!!!

i re-sealed everything, started it up (4.2 turbo diesel by the way) put the bag over the head on top of the snorkel, it sucked back through the fins & popped the bag, so i put a rag over the top (safari style head) then put a new plastic bag over, the suction was enough to start bending the fins on the head backwards, slight rev change, but no stall!!!!!! is this right or should it stall????????

thanks!!
