Snorkel Question

i WAS WONDERING WHAT THE POINT OF A SNORKEL ON A GAS ENGINE IS BESIDES CLEANER DUST FREE AIR AND EYE CANDY. i MEAN, tHE INTAKE ON A DEFENDER OR A DISCOVERY IS ABOUT THE SAME HEIGHT AS THE DISTRIBUTOR SO WON'T THE ENGINE CRAP OUT IT THE CAP GETS WET REGARDLESS OF WHERE YOUR air intake is located???

sorry for all caps

Yes a wet dizzy will end your trip through the river or mud hole but once the dizzy is dry the vehicle will start back up.

An engine that has ingested water is toast. Liquid does not compress so when the cylinder is full of water the water has nowhere to go during the compression stroke. End result is you need a new motor.

The wading issue is not the overriding reason to get a snorkle.

Dust free air and cooler air is the real reason. The air under the bonnet in the heat of summer is quite hot from the engine and the tarmac. That hot air will not carry as much fuel and your performance may suffer as a result.

If you have ever experienced buffalo dust then it does not take long to figure out that all of that particulate matter will not extend the life of your engine.

okay but i at least I understand the wet distributor end of the deal.....is there many way to waterproof your distributor. I know that I can never have the same wading capability as a diesel but just looking to see what the real story is.
PS--I thought that a snorkel actually decreases performance, when I read what you wrote it sounds as thought the snorkel increases performance???? whats the skinny?

If the snorkle is designed properly and does not restrict airflow then it may enhance performance but in most cases the increase would be hard to notice. Engine longevity is more what it is about.

There are rubber boots that resemble a cows udder that can be used to help protect the dizzy from water ingress. Look on the brit parts houses websites for them.

One thing that you don't want to do is silicone your distributor cap to the base and gum up the works with a lot of sealant. This approach is a huge mistake.

If you are facing a particularly deep crossing, it may be prudent to remove the fan belt temporarily for the crossing. If you have electric fans in lieu of a vicous fan, then you can rig a switch to disable the fans for water crossings.

Proper wading technique i.e. creating a bow wave is the best defense against soaked electrics in the long run.

Follow-up Post:

There is a good write up here on wading.

A trick I have used for years on my Series 3 88 is a rubber glove over the distibuter. Clip the tips off each of the fingers, feed the five wires through, a few tie wraps to seal it up and the cap is virtually water proof. I've had my truck into some fairly deep water and it hasn't missed a beat.

And like was mentioned earlier, it's all about the bow wave.

Ron,
When you got rid of your dizzy, what did you end up going with???
