Coil question

I have had both the mallory and msd coils on different cars and both were running mallory unilite distibutors and ran great. one question i had was did the car run ok with the mallory coil before you noticed it leaking?

Yes, in fact it was running flawless. That's why my gut tells me it the coil or the module got fried. I had the ignition on for a long time while working on some interior lights and that's what caused the coil to boil up. Just for clarification I have the magnetic breakerless distributor. I thought it was a unilite but I was wrong. I was told the breakerless has a more durable module and I am hoping its not the problem.
