Thank You James. That does make sense to use just soap and water on the cap provided all the wires are removed. I will start on this tonight. It will keep me from munching on chips in front of the telly. I'm hoping my wires are good as my budget is strained to the max from the full service job on the car. I'll keep my fingers crossed.

Jeff- I did exactly as you suggest. Remove the distributor cap, unscrew the spark plug and coil wires, clip off the fried/cracked/corroded ends, and reinsert. I silicone'd the screws. I removed the central carbon brush and cleaned and silicone'd so that it "floated" on the spring correctly. Do not use a solvent on the inside of the cap. Soap and water will do.

The spark plug wire resistance, I believe you will find, will vary from infinity to 5,000 Ohms. If you find this kind of variation, I would replace the set of 12 (expensive). No sense in servicing the engine and not having consistent resistance in the wires.

My thoughts.

I'm in the home stretches of completing my TR engine, and trying not to get too excited and rush through things. The last thing for me to do is to clean and inspect the distributor caps, and check resistances of the plug wires. My caps appear good with no cracks, but are dirty inside. Is it wise to remove the plug wires from the caps? If so are they secured by the slotted screws at each terminal? I will use fine sand paper to clean up the terminals unless there is a better way? Are there any surprises waiting for me as I do this job? Can I use electrical contact cleaner to help clean out the caps?

I had one cap where the carbon rod/spring were toasted (pun intended) but did find a replacement for them locally for a change. After trying to match it up to what few foreign caps they had, I just said let me rummage through all of their stock until I find one. So they did, and it ended up being an application for the Mercury Tracer that had the same carbon rod (different spring...I'll cobble up one of these easily). You just never know where you will find something that will work.

Any advice is greatly appreciated.
