Re: Clean Engine bay
I'll tell a story here. It will illustrate just what is happening here with this thread.
A pair of main thoroughfares near my home years ago used to flood for a couple of hundred yard s each direction from the intersection. I had a '69Chevelle hot rod with rusted body. Work car but not the primarty family vehicle. I would get a can of WD40 and spray the secondary wires. Just the secondary and distributor cap. Then I would go out the flooded area. And drive through the water up half way on the doors. Others would watch me and figure they could do the same. NOT! Now they are dead in the water (no pun here) and wondering what happened! I would walk out in the water wearing an old field jacket inside of which (out of sight) would be the can of WD40. Nonchalantly I would inform the driver that for a small stipend I would get them on their way in just a few minutes if they were interested. They would look around at the lake in which they were stalled and break fingernails getting to their money. It was never less than $5 and sometimes as much as $20. I'd take their money and tell them to pop the hood. Hood up and lean over the engine and reach into the coat sneaking out the can of WD and spray the secondary wiring (10 seconds) and back into the coat with the WD and go to the other side and repeat and hit the dist. cap at the same time (another 10 or 12 seconds). Stand up, shut the hood and tell the driver to start it up. Sometimes they would argue at this point but I would just insist that they start it up. Then it was just a matter of trying to keep a straight face when their recently dead vehicle would start RIGHT up and just purr. 4, 6 or 8 cylinders, foreign or domestic, water or air cooled, old or new, fancy or plain, it NEVER failed to work for me. Some times I'd make a cool hundred in a hour or so.
Point is that most of the time it is not the electronics or water inside the distributor cap, it is secondary leakage through spark plug wires and terminals at the cap or plugs and the water path to ground. WD drives the water away and presto/chango all of the plugs fire again.
WD is good but the best is LPS 1. With it you can run your motorcycle dirt bike point ignition mag system under water without a mag cover and you can cut two holes in your distributor cap and spray inside and then hood the garden hose to cap and have full water flow through it and never have it miss a single fire. I have helped demo this.
