hey stupid question... i got a 89 f250 fuel injected.. just wanna see whateverbody does to protect everything from water..seem to always have eltrical probs with big puddles.....ne wayz thanks
Look for silicone spray in a can. It'll help with the dry rotted seals around the connectors. Also find the source of the electrical problem, if it's corroded wires, bad connectors, or faulty parts, replace it.
When I have my electrical connections apart, I'll put a little die-electric grease in them before I put them back together.
Just a thought... You might try running water with a hose or some type of mister over different parts of the engine. Maybe your problem will show up when you do that.
How old is the plug wires?
I've seen hair line cracks in the distributor do the same thing too.
Yeah I go through alot of water around here, you see more of it in Washington then most things. Use di-electric greese on your connections. If you have WD-40 i've seen that helps to keep the water off things. Don't SOAK it in it cause you'd have the same problems as water. But water will run off of most things coated lightly in it.
Your distributor cap would probably be the biggest thing. If water is splashing up on it, as long as its a good cap it shouldn't let water in.
If your splashing through water you shouldn't have that big of a problem, if your driving into deep water you should check your gear oil and such, because water WILL find its way into the axle.
silicone your distributor cap and middle part to the distributor. use dielectric grease on everything else, make sure the plug wires are new put dielectric grease in them also. Make sure your air intake tubes are not cracked, I have seen that also, they look fine but bend them around a little they may be split.
On mine there is a "breather" cap, atleast thats what it looks like its for....
I have yet to get my distributor wet on this truck, ive done it on a car before that i was boggin in, but not on the truck...
I usually try to stay away from water... Ive had bad luck, im not so worried about electrical connections you can dry those out, but that big air intake for the engine, thats what im mostly worried about, you suck water, you dont exactly "dry out" an engine....
Its usually expensive and means a rebuild, atleast it did in my case.
I stay away from standing water, fording rivers and creeks is different, i take it as fast as i can with out kicking water up to high....
Warning!!!!!!
Temporary thread hi-jack about to commence!
Tininan I see your sig says you are using a 91 D60 any reason you used a ball joint d60 over a king pin d60? if that axle were like 3 years older it would be a king pin and not a balljoint....
Temporary thread hi-jack has terminated. Thank you for your time!
the large diameter male style dist. cap have a breather on top, they apperantly won't let water in the vent because the one one my old 351m ran fine completely submerged, on my new 460 I have the small diameter cap with female terminals and no vent, i haven't siliconed it yet but when I do I will leave a 1/2 inch or so unsiliconed in the very back
My Bronco had a 302 in it. I completely sealed the distributor and the spacer on the bottom, didnt leave any gap and used dielectric grease on all the boots. I also used the grease on all the electrical plugs and snorkled it. Had it over the hood in water numerous times and never had any problems...related to the water atleast.
Of course it was carburated, so I had alot less electronics than a EFI motor. Water really isnt too much of an issue on EFI's as long as your airbox stays dry. And I say that thinking that your not going over your hood in water. Sure a splash or 2 over your hood shouldnt do anything, but anytime your sitting in water for long you will have big issues coming your way.
If your having problems you probably have some exposed wires somewhere.
