What causes corrosion inside distributor cap?
One of the most common reasons, is that your distributor cap has a hairline crack that is admitting water and condensation. At times, the distributor cap needs a new gasket, and if the old one is not replaced, it leads to corrosion.
Is there any way to keep moisture out of a distributor?
I know I sprayed some kind of clear sealer (maybe silicone) over the cap and wires but never really had a weather issue anyway. Moisture can get inside of the distributor cap no matter how tightly it has been sealed. The key factor is the dew point in the atmosphere.
Can You Spray WD-40 on a distributor cap?
Moisture can get inside of the distributor cap no matter how tightly it has been sealed. The key factor is the dew point in the atmosphere. Spray it down regularly with WD-40; especially at times of the year when it’s very humid or cold and damp. Fender1325 July 6, 2016, 4:58am #7 Thanks guys.
What causes distributor cap to be dark inside?
Notice the dark iron oxide area on the inside of the cap. Our guess is that the inside of his rotor was absolutely filled with this stuff. Also notice the whitish aluminum oxide deposits on the spark plug wire terminals. That’s not good. Jeff Smith: At first glance, I thought the dark area on the cap was grease.
What can I do to keep my distributor from leaking?
Spraying the outside of the cap and wires with silicone might give some water protection… I wouldn’t worry about it, just make sure you have all new parts, and when you take it out drive it long enough for the engine to get thoroughly warmed up.
