Hmmm, I should ask justinc how much it costs to install a diesel isuzu in my Rangie

depending on how permanant you want to go and how much ease of servicability you wish to retain will change the cost. The simple way is to be very generous with the sealastic gun and it just gets more complicated from there up to and including secondary shields over the plugs and leads and compressed air flowing thorugh (at about 1-3psi) all the major electrical components with a driver controled fan clutch to disengage the fan drive and an isolation system for the alternator so that its not going to arc out while under..

I have once seen a petrol old school engine running with about a 3 foot head of water over the rocker covers.. just to prove it could be done.

However, i don't believe the comment your replying to is 100% correct (

), as water can still splash/spray into the air intake before you're up to your knees in water. IMHO a snorkel will solve half the problem of swimming 4x4s, and more importantly, solve the more serious one (water in the air intake can be very bad news, water on the dizzy means SFA except the car stalls).

As with all my technical posts, please correct me if i'm wrong

nope your pretty much on the money but the amount of water that is usually sprayed up into the intake of a petrol engine (assuming its stock as designed) will be passed through the engine without too much hassle it'll just run a bit rough for a while and maybe better after as the cylinders will have been steam cleaned. Diesels are a differnt story.

I guess you get what you pay for

The supplied template appears to match the three bolt holes on the snorkel, so is it the position on the guard that is out?

Cheers,

Hey Ron,
I found the position of the large hole to be slightly out and the fixing stud nearest to the hole to be out. The template appeared to be a photocopy which seemed to have lost some of the correct proportioning?!?

In the end i took the quarter panel completely off, installed the "dogs leg" bit, replaced the quarter panel, then drilled a 25cm hole into the correct spot, enlarging the hole with a series of drilled holes - finally finishing off with a half round file.
This way i was working from the airbox back to the final fixing of the snorkel, as opposed to fixing the snorkel only to find it's in the wrong spot

Thanks Phill,

I guess that is why they have in big letters, "GUIDE ONLY"

The main purpose for a Snorkle is:
1: To enable water crossings without water entering the motor through the air intake, thus causing damage to the motor.
2: To enable clean air to enter, and not suck up dust from your own vehicle.
As to the RAM air theory of more power who are we kidding, we drive Landrover's, If you want more power buy a Sports bike.
As to the only problem with petrol vehicles just stalling in deep water crossings, because of the electrics. Where do you think all the water goes,once it has stalled, back up the exhaust and into the motor.!!

I used to drive Champs in the army reserve in the early 70's, The water crossings were the best (only??) feature of them due to the marinised RR engine. There are probably a few seat squabs out in the ocean by now as they would float away in the streams

just wondering if anyone has fitted the 4WD Systems snorkle to a S2 Td5 Disco? - any problems with fitting this particular unit?

They're around $300 and available in colour coding:

Hi there bulldog, I have posted somthing in the tech section 'Home made snorkel for disco, I made my own and it is great much better air flow I made it 80mm all the way through, have a look there are a few pics as well. I have a V8 disco
