Anyone run into this before? I haven't in any vehicle I've owned. At first I thought the leak was from the main seal, but luckily found it was from where the distributor attaches to the engine. How tough would this be to fix myself? Anything I need to look out for? I'm concerned about pulling the distributor and messing up the timing (and then winding up having to be towed to the garage). BTW, the vehicle is a '94 JX 16 valve Sidekick.
