What causes my son's 92 RS 3.1 to get loaded with scale inside dist cap in less than 1000 miles?

 

May be moisture from the air or engine in the past I have blasted the inside of mine with wd 40 and wipe it out leaving a film on the inside. Living in the rain forest creates a moisture problem.

 

O.K. I WD40'ed the cap inside but I remember something about ionized air in the cap. Do I need a cap that is vented ?

 

I really don't know about a vented cap but the ionized air sounds very interesting is the timing on the money and how old is the cap.

 

Timing is at the spec and have gone thru 3 caps and 3 rotors.

 

Sorry it took so long to get back to you I was working on my car.All I can think of is some kind of arcing inside of the cap. If it was my car I would check out the rotor and cap very closely. Drive it for awhile after the wd40 and see what happens.

 

I have been searching the forum for some help for you have not found anything yet.

 

Thanks for looking, but as an aside this car never passes the emissions test although it starts really fast.

 

I would make sure the rotor is being pushed all the way down onto the dist. shaft.

 

I am still here just got off work. Looking at my book today and there are a few things that can be adjusted inside that dist. There is an air gap between the pickup and the trigger on the shaft under the rotor. I haven't been very much help but a book on that engine would be real helpful for you.There is also a capasitor wrong spelling that I could not find what would happen if that went bad.

 

The rotor is down as far as it will go and this distributer is only 1 year old. The capacitor you refer to is (I think) a condensor that was used with a points type ignition to stop deposits from building up between the point gap.

 

I remembered something today, one time I was working on a boat and when I pulled the dist cap it kinda looked like what you are explaining and it was a bad coil. Now I am not saying buy a new coil but in the books for these cars it tells you how to check. The spark was to weak to jump across so it was jumping up and causing the white scale.
