I once had this problem occur and it ended up causing me a big headache. The distributor got "steamed" when I went through a big puddle that splashed water around the muffler, etc. The engine started "cross-firing" because of the wet distributor. By the time I pulled-over and popped the distributor cap to wipe it dry, the cross-firing had caused a blown head gasket. I ended up having to drop the engine and go through all the drama of making the repair, all because of splashing through a puddle. My advice would be to do whatever you can to avoid repeating my mistake! Silicon-seal might be a good idea... it stays 'soft' so you can take the cap off later when necessary.
