Water proofing Distributor

After mudding on sunday My truck wouldn't start. I wrang out the foam element on air cleaner(Best money I have ever spent) and cracked open distributor. It was wet of course. I think it was condensation more than water because it was wet after I had dried it out. I am wondering how to keep it dry in there. I was thinking of a sealing it up and then running a vaccum loop through the distributor somehow to keep a small amount of air circulating through it. Ok, now how do you really do it? Also what is a alternative to the expensive air cleaner oil? I washed the mud out of it but it now needs to be reoiled. Will WD-40 work?Thanks. See dirty pics post to see how this happend.

Re: Water proofing Distributor

<font face="Comic Sans MS">You could... Hook up an aircompressor connection set to a light pressure to the top of the distributor cap with a small nipple, and put another one under the base of the distributor. The lower one can be used for vacuum. This keeps the cap vented out and pretty much water proof. You could seal up the base with silicone sealant. Don't seal the cap without some means to vent it, because ozone will build up in there (ionized air actually) and cause cross firing after a while... [img]/wwwthreads_images/icons/crazy.gif[/img]

There is no real replacement for the K&N oil if that's what you're referring to. At least no suitable one to my knowledge... [img]/wwwthreads_images/icons/crazy.gif[/img]</font>

Re: Water proofing Distributor

I didnt get a K&N I bought an accel, It sits on a frame and can be pulled off and wrung out like an old sock. I guess it uses the same oil as k&n. I am concerned about the compressed air because it would come out cooler and might create more condensation than running in deep water. I know not to seal it up. Jaguar had a problem with that on thier V-12's they solved it by running a vac line to top of distributor. To suck out gases before they could combust and crack distributor. I think it was hydrogen though. Thanks for input. Heres a pic of foam air cleaner. I put two threaded rods together to make it work.

Re: Water proofing Distributor

<font face="Comic Sans MS">Typically compressed air is warmer than ambient air because it is compressed and the molecules bump eachother more which makes the air heat up... [img]/wwwthreads_images/icons/crazy.gif[/img] I don't think hyrdogen can build up in there. But the best way to keep water out of the cap is to pressurize it a little bit with some compressed air, because that'll force the water out... [img]/wwwthreads_images/icons/crazy.gif[/img] A vacuum line to the distributor would make you draw more water into the distributor... [img]/wwwthreads_images/icons/crazy.gif[/img]

Re: Water proofing Distributor

I'll try it. I guess a little el-cheapo compressor would work. Just kick it on when I am going to get wet. Thanks.

Re: Water proofing Distributor

How come when I do an internet search it always brings me back to offroad.com but I can never find the stuff here on my own? Any rate here is a article on waterproofing I found here. http://www.off-road.com/toyota/tech/water_crossing/

Re: Water proofing Distributor

FrankP, As far as washing and oiling the foam pre-cleaner, I bought a K&N filter along with there foam pre-cleaner. I use the K&N oil for the regular filter, but I use 32:1 gas (from my weed-wacker) and oil mixture to clean and oil my foam precleaner all in one step. I take the foam precleaner and put it in an old tin coffee can (one of the big mothers from Costco, not the kind you used to get at the local grocery store) thats filled with the gas oil mix. The gas cleans out all the dirt, grease, and crap after a few dippings and wringing outs. I then let it try (the gas evaporates, and the light oil stays behind to help trap dirt). Make sure the filter is dry to the touch before putting it back over the paper/cotton filter or otherwise it will wick fluid from the precleaner. I've done this for all sorts of precleaners. I started doing this on a commercial walk-behind mower with a 17HP Kawasaki and it worked great, so I have been doing it ever since without a single problem.

If you didn't built it yourself, how can you call it yours.......

Re: Water proofing Distributor

This is not a prefilter, its one main filter sits on a metal frame. I'll try your suggestion, sounds combustable !

Re: Water proofing Distributor

You could drill a small hole in the top of the distributor cap and the put a bead of silicone around the base of the cap. The hole will allow the cap to still vent but when you want to go play in the mud just smear some silicone or some thing else over the hole to seal it and when your done just scape it off. Also if you have the small door in the cap for silicone that shut to.

If it aint broke, keep fixing it till it is.
