Is there a way that I can make a snorkel out of the factory airbox on an ea81? Or something that will connect to the carb?On the cheap? Also does anyone have any tips on how to protect the disty from getting wet?

Seran wrap and duct tape.

The problem with the dissy is the breather hole on the bottom of it. I plugged mine, then drilled a hole and used a piece of brake hose pushed into the hole. Ran a vac line from that to the airbox where I had a spare plug. You need the dissy to breath so this is a must.

 

Also what can work really well for a short time is stuffing huge amounts of grease in your dissy. All over the points, cap, rotor etc. Water gets in but doesn't effect spark. You will found however that after a couple of days of driving with this your will start to loose spark. This is because the grease burns and turns into carbon which conducts... So around the cap the spark will travel to what ever lead it wants.

 

For the carby I once made up some PVC drain pipe adapters which worked well on a friends car. 65mm 90degree bends I think they were. Cut one side doneto just whre it elbows, drill a hole in the "top" extended the threaded rod from the carby etc. Also drilled and threaded some holes in the side for crank case vents. Then using some large industrial vacuum cleaner piping we attached this to a Liberty airbox which we had already modified to take the custom 2" steel snorkel we made up.

 

If you search on here for snorkel you'll probably find some images I've posted up in those... EDIT: or not because I just had a look and the images are gone, not sure where I had those hosted....

could I run a bead of dielectric grease along the bottom of the cap to help seal it or would that really do anything?

You can, but you still have a 4mm hole on the bottom right between the block and its self where water splashes over that sucks up water. So it won't do much. Basically you need a breather first, then seal it up. If its easier for you you can always put the breather in the cap. Some EA82 caps have a breather, maybe some EA81's do too?

so where is that vent hole?

i used to carry a spare cap and rotor in my glove box when i had my old 85 wagon. that was such a pain. i also learned the hard way to swap the plug wires one at a time.

On the bottom, at the back of the disty on the EA81. Back as in the towards the rear of the car.You can't see it with the disty in the engine.

If the cap is sealed with a bottom vent, wouldnt that create an airbubble at the top of the disty?Even with the car underwater? Remember the upside down glass in water experiment?

sounds like an expirement. seal the cap on with form a gasket and see.

I'm pretty sure there is a gap down between the shafts that the crank case sucks air through, thus its always pulling the air from inside the disty.
