I have an '86 944 in need of some TLC. Right now I'm working on the ignition system and I've run into something that puzzles me a little.

The distributor cap is loose. I've attached it and followed a pretty standard cap replacement procedure, but I can't seem to get it to seat against the engine tightly.

Any thoughts or suggestions about what might be wrong? I looked through the archives, but didn't see a similar problem, so I thought I'd ask. If a picture or something would help advice I could post one.
