waterproofing EJ22

My rig isn't really an offroader, but I figured this would be the place to ask.

 

I've noticed that the first gen EJ22 engines have a lot of trouble with water getting down into the spark plug tubes, which causes arcing that destroys the plug and boot, leading to a horrible misfire, which is not very helpful when you're trying to drive through deep water.

 

Surely you offroaders have figured out a good way to seal around the spark plug boots to keep water out. I've thought you could either just put a crapload of dielectric gease there, or use some of that light blue RTV that doesn't stick super hard.

 

I'm also curious about the air intake. I know it goes into the fender, but what happens in there? Have you had trouble with sucking water? I've thought about bypassing the whole fender area and cutting out bottom of the airbox like people do on loyales, because at least then the whole underhood area would have to be submerged before it sucked any water.

 

What are your thoughts and/or experiences with these two areas?

 

Any other places on the engine or electrical system that are particularly susceptible to water intrustion?

 

Thanks for your help.

not very long after that i believe he blew some idler bearings too.....i would silicone the timing belt covers,try an fill in the spark plug hole/gap if your wires do not, and cut all the crap off of that intake and take it straight back into the spare tire well.just take the 'm.a.f." with it.cheers, brain
