I managed to stall my Patrol mid-stream on the weekend, but eventually re-started it and drove out under my own steam.
With the help of my mates, we concluded that the stall was caused by a combination of
water mist on the mass air flow sensor (which caused the emc to massively increase fuel flow, flooding the engine) and
water ingress in the sealed, vented distibutor.
The first problem we can prevent with a
snorkel, but the second one is more of a challenge. So here's the question:
Has anybody fitted a tube to the distributor vent, so that it can vent to an atmosphere less likely to contain
water (such as the snorkelled airbox?)

why not just seal it?
I cannot see enought
water getting into the dizzy to cause a proplem over a
river crossing.The most likey cause would be dirt on the HT leads making the HT "track " when
water entered the engine bay.

Water was plainly evident when we opened the distributor.
I have read that (otherwise sealed) distributors are vented to allow the escape of
water vapour entering via shaft from the engine. Over long periods, the tiny amounts of vapour so entering condense and collect in the cooler distributor chamber.

well when you stop to put the blind across your front of the car, you can pop the bonnet and stick a piece of sticky tape across the vent hole.
Do the ford then remove the blind and stick tap.

Nifty Patrol, you wouldn't be in Vic and had a Humvee with you on the weekend would you?

My last vehicle... A GQ RX 4.2 EFI 1994 used to stall in the middle of all
creek crossings and could restart again once the turbulance in the
water had dispursed and idle but once the
water started getting moved again the vehicle would stall...Until i got winched to a shallower part and i could restart and move out of the
water...
I tried taping the dizzy cap because of signs of moisture and tarping the front of the vehicle and it would still always stall...
So when i got back from a very wet
Cape York trip someone told me that i had some sort of crank sensor which was being effected by moisture but i never ventured to fix it because i saw the light and bought a diesel..

You may find there is also a hole in the bottom of the dizy, so instead of blocking the top hole or running a long vent tube, if you have air on board to regulate it down to 1 to 2 psi run that hose to the top vent and make sure there is another small hole in the bottom of the dizy. This way the distributor will have a positive pressure and
water will not enter. In saying all this, it will keep the inside of dizy dry but there is a hell of a lot of other electrical spots that don’t mix
well with H2o, but look at the
bright side, will give you a good reason to get out in the shed and suck some pi$$.
