I've been having some starting and occasional running issues with my Mk2 (ABF running on 16v Kjet). Tonight whilst poking about, I found that there was a pretty decent amount of oil under the rubber boot for the king lead on the dizzy. I noticed it was seeping out from under the rubber cover on the end of the lead, pulled it off, and there was enough oil inside to drip off and make a decent mess. None of the other HT leads were contaminated. I cleaned it out and replaced the lead - the inside of the dizzy is bone dry, as is the cap. I didn't pull the king lead out of the coil as it was dark and didnt want to unseat the coil connectors by accident.
So, do Mk2 coils contain oil (coolant?) and if so, could it be passing through the length of the kind lead to the dizzy?!

I can't see how it could have gotten there otherwise!
