: Ive been in water up to the windsreen wipers afew times, thats with
: suspension lifted, 30mm body lift, and 36 inch swampers. Even had it
: running in the drivers window once when it was deeper than it looked and
I
: didnt put the window up.
: 
: The only trouble when its that deep is it is usually running fast as well : so
you have to drive in and head upstream so the water washes you back to : the
exit on the other bank of the river. Quite often the back of the 80 : will float
which spins the car around facing the water and easing the side : pressure of
the water on the car allowing the car to drive out. : : The best waterproofing
Ive found is drill and tap the breather hole in the : distributor, and put an
air fitting in and hook it up to an air horn : compressor so it changes the air
in the dissy to prevent condensation and : pressurizes it to stop water ingress.
I then cable tie a plastic shopping : bag around the dissy and the coil and duct
taped the air flow meter plug : and any other that I didnt want water in. I also
permatex gasket makered : the plugs to the head on the rubber flange area, but
just a smear so they : are easy to get off again. If you run LPG you need to fit
the safety switch : out of harms way as they are not waterproof and can short
out cutting off : fuel supply when full of water. Also you need to run breathers
from the : bell housing after sealing up completely, the diffs, gearbox and
transfer : case, you can also fit air fittings in the swivel housing plugs and
run : breathers from here. Also you need to duct tape the little rubber teat on
: the bottom of the air cleaner to prevent water ingress from this point. : :
You dont need to extend the tail pipe as the water only gets up here if the :
engine stops, and if water does get in the tailpipe as long as its clean 

: (muddy water will do a good job of overboring the cylinders)    it wont
do
: any damage, you just pull the plugs out and crank it over before changing :
the oil and filter as soon as you get it out of the water and you are ready : to
go again. : : The fan should be viscous and will stop as soon as it touches the
water as : long as you dont hit the water to fast (high range instead of low
type : speed) if you do hit the water to fast the fan will think its a propellor
: and try and take off forwards carving a nice neat circle out of the :
radiator. : : Regards, : Darren McRae
