I have a '93 F-150 with a 302. One problem with this truck keeps reappearing. The distributor gets wet WAY too easy. I get tired of replacing rotors and distributor caps. Is there an electronic distributor that I can buy as a "drop-in" replacement that is better sealed against moisture?
I run a GM HEI distributor in my jeep (AMC 232 engine) and it never has an issue with water. I'd like for my truck to be the same way. Any thoughts? Thanks for the advice!
Are you saying you have an ignition problem in wet weather? If so it's far more likely the coil and/or wires are the problem.. and not the distributor.

If you decide to get a new distributor, consider our custom curved Duraspark Distributor built with our new Full Length Oil Impregnated Bronze Bushing. The full length bushing improves timing stability and spark scatter. If stock appearance is not an issue, take a look at our one piece D.U.I. Distributor. Whether you choose the Duraspark or the D.U.I., we curve each on a distributor machine based on your engine combination. Please see them at: http://performancedistributors.com/forddistributors.htm
Also, there is now an excellent installation article on the D.U.I. Distributor on the Ford-Trucks.com site at: https://www.ford-trucks.com/article/idx/0/358/article/DUI_Ignition_Installation_In_A_Ford_351W_V8.html
I can't think of any ignition setup that would offer a better seal for the distributor cap; this is kind of an odd problem. I'd have to agree with what was mentioned above; and I'll add that you might have some exposed wiring somewhere that is actually the culprit. I have a straight six in my pickup and the distributor is actually exposed to the ground because of how the engine is configured, and I don't have problems. I'm using that example to illustrate the point that the ignition system is not supposed to be as sensitive to moisture as you're seeing when everything is in order.
I agree, it's such a weird problem that the moisture might be a red herring. Typically moisture effecting the ignition means a cracked distributor cap. In the days of point ignitions when we got a road call on a damp day for a no start condition, we didn't take anything to the vehicle except a distributor cap and it would fix it EVERY time. Since the distributor cap has been changed, it makes this one a stumper.
Thanks for all the input! And yes...this problem does seem odd. All I can say is the truck has been in the shop at least five times in the last few years for rough running. It's ALWAYS the ignition. A spark plug here, a rotor and distributor cap there. At least once they replaced everything from the rotor on out (including all the plugs). The ignition fix never lasts more than a few months and I'm right back where I started again with a rough running truck.
I'm getting real tired of replacing the same parts over and over. My thinking was that maybe an electronic distributor would help the situation. It might not, but I'm ready to try a new approach to this problem.
FWIW I have had wet weather problems on every Ford truck I have owned and it always traces back to the coil or wires, the distributor doesn't affect it no matter how bad the terminals inside look.
A Duraspark is tough to beat for the money. The junkyards are full of them and they work great.
As far as junkyard Durasparks are concerned, beware of their worn out upper bushing-they only have one. We utilize a full length oil impreganted bronze bushing in our Durasparks. This improves timing accuracy and it will be more durable for you. Junkyard Durasparks also can have worn out advance mechanisms.
I would have thought that is was already electronic, since Ford started using the Duraspark about 1975. But, a little trick to keep moisture out. VW used to use hairspray from the factory to seal out moisture. Dizzy sat right under the air vents on old Beetles.
I'd try a 5.0 mustang rubber boot for the distributor first. don't forget to use some dielectric grease on all the connections. .If you still have issues a remote TFI might help. Most guys I know doing the remote tfi have heat issues more than water though.
Thanks for all the suggestions guys. The next time I send it to the shop, I'll let them tell me what's wrong THIS time. Then I'll try to use your suggestions to make the best call on how to solve this problem.

A 93 would already have an all-electronic TFI distributor. Also I'm not sure how it works on the 5.0 V8, but on my 2.9L Ranger the computer gets the signal to fire the fuel injectors from the distributor as well. If you swap out your distributor with a different type your engine probably will not run at all.
