MSD blaster 2 coil just popped its top and sprayed oil all over my challengers engine bay.

I have one season of cruising on it! I had left the key on while trying to fix a ground problem for a signal light issue, may have been about 1.5 hrs (kinda forgot about it), while cleaning up, I hear a hiss and look over and see the coil is smoking and spaying oil!!

Turns out MSD dosn't recommend mounting horizontal ( which I did), but looks like I am in need of a new coil, preferably one I can mount horz. Any suggestions?

Damn . The blaster 2 has 0.7 pri ohms and I'd go with a Pertronix 2 coil (0.6 ohms). were you running the recommended 0.8 ohm ballast with it. My first FBO coil was leaking out of the top after initial startup & Don replaced it for free bless his heart after I sat on it for a year then contacted him & the one he sent died on the road in short order (started missing then 15 miles later the muff exploded & almost scared the guy behind me into the ditch) as I coasted into the other lane then to the side of the road

Get an epoxy filled coil. ("Vibration Proof") mount it any way you want.

Coils will do that when ON for 1.5 hours or less

I learned my lesson on my Blaster II coil when the cap started leaking all over my valley pan from being mounted horizontally. I mounted the replacement at a 45º angle on the valley pan rail. When I drive it gets a perfect blast of air so it doesn't overheat...but yeah...1 1/2 hours stationary will do that to ya

It wouldn't have happened with a CD ignition. Just sayin'.
R.

That sucks. And I hate to hear it.

I must be lucky, ive had a blaster 2 mounter sideways and even one time left the hot switch on for near half a day.

This makes me think I need a new one or I have a really good one. But I think I will order a spare.

How do the old big accell? supercoils do in todays more modern world?

a few years ago, a had a '58 chevy wagon. 283. i put a petronix conversion in the dist, and used one of their coils.
i had it running one day, and was adjusting the timing, when my hand hit the coil, it burned my hand. then i noticed the top of the coil was starting to melt!
