This usually happens on hot days. It'll crank, but no ignition. Sometimes the S3 light blinks, sometimes it doesn't. If I get 'er started, 6 times out of ten, it squeals.

I looked at the plugs, very oily. This weekend I'm chaning the plugs, oil, and distributer cables (some dry rot there). Are there any gaskets I may need to replace to stop the oil?

I think the oil in the plugs is the culprit for the non start, but the S3 light and squeal make me nervous about the clutch.

Any ideas?
