Wet Distributor
Is it common for the distributor to collect moisture after the car sits in the rain all day? ( 88 Targa 3.2)
Happened last week, at first it started like normal, drove about 5 miles and parked to go into store. When I came back out.........would not start
. I quickly found the problem and corrected it.
Just wondering if this can be expected after evrey rain.
Thanks much............KC

KC:
If the distributor cap interior is cracked or carbon tracked (makes a conductive path), you will have trouble. Same goes for the rotor.
These will collect condensation if they have a small crack.
Make sure that your DME relay is fresh and there is zero moisture under the driver's seat as thats all too common on Targa's.

A common problem on 3.2's distributor caps ('84-'89) & 964/993's, is moisture
being trapped between the black distributor cap shield and the cap itself.
As the cap ages or cracks, the high voltage will breakdown to the shield which
is basically a "ground plane" used to suppress RF radiation.
If you look at the cap you'll see how moisture can become trapped between the shield
and the actual cap. The shield ends at each plug wire connector providing an entry
point for moisture. Sealing this "interface" with a clear high voltage dielectric spray
reduces the likelihood of moisture being trapped and a high voltage breakdown from
ocurring, e.g. like a resin based spray paint.

Burning Brakes
I'm in the process of replacing my plugs, plug wires, rotor, distributor cap, etc. for the first time. I've got a tube of silicone (dielectric) grease (not spray). I put just a thin film on the inside of the rubber spark plug boots when installing those. I was also going to put a thin film on the insides of the rubber distributor cap boots, and also on the bottom edge of the distributor cap itself. Am I on the right track? I"ve seen some directions which seem to 'coat' the spark plugs (along with the boots), etc. Point me in the right direction guys...and I thank you in advance!
