How To Repair A Coil Pact

My curlicue packs went out on me on the dyno. Needless to say I was a piddling upset. So I started to search for a gear up cause I'm cheap! LOL! All I could detect was the old 3m tape trick. So I tried that and it worked for a little while. And so about iv-v days later low and behold they started the same crap again!

At this betoken I was about to bite the bullet and spend the coin on Split fire coils. Before I did, I wanted to pull the coils out and see exactly what was going on! They were firing threw their plastic housing! There were pocket-sized, I mean Pocket-sized cracks in the plastic housings on about 4 of the coils. I hooked them up and started the car up and turned out all the lights in the shop! Talk about a light show!!

This told me the coils themselves were actually working! It was but that at that place housings had failed. I'm a Honda tech past trade and I've seen a endless number of internal coils on Hondas go out due to the heat that they suffer being inside of the distributor. Now on the Honda models that have the roll on the outside of the benefactor away from all the heat, they never accept a problem. Long story short it does appear to be a failure in the coil housing due to heat.

So I ready out to see if I could remedy the housing problem. (Since the coils still seemed to exist firing good.)

I looked around at destine of coatings and the like merely I remembered how I had made my motor mounts in my car! I used a ii part urethane. It'due south called Flexane. It's made past a company named Devcon.

Heck it was a existent good urethane that could be brushed on or even used to dip things in. So I decided to give it a endeavor.

I bought two of the kits and mixed nearly ½ of the first kit upwards and gave all the coils a expert glaze, making sure not to get it on the plug surface area or the side that connects to the spark plugs. I took off the rubber kick on the bottom and used some plastic plugs to brand sure I didn't go whatever in the hole. I also didn't glaze where the electric connectedness plugs into the coil. Make certain y'all don't put any under where the plug volition go also. I did this and ended up having to cut off the urethane so that the electrical plug would snap all the fashion onto the coils. I hung them upward using some wire to let them dry out for about 4 hours or and then. I mixed another ½ batch of the Flexane up and gave them all another good coat. I let them fix some other 4 hours and repeated the footstep once again. I let them set up overnight and gave them ane more good coat. Now yous don't want to get too carried away. This stuff builds upwards fast. If you put besides much on you'll not be able to get the coils back in their retainer! I let them set over dark again.

I put them back on the machine the next 24-hour interval and ran the auto HARD! It ran great! I pulled the plugs back out and re-gaped them to 1mm and drove the car again. I put near 50 miles of hard driving on them and they worked Bang-up!! Non miss firing or spitting at all! I got the automobile back on the dyno and it ran neat. I've put over 600 miles on the car and then far and have not had the slightest trouble out of it! I was too considering going with the wasted spark ready upward only this has worked smashing and then far!! Hither is a pic of the coils coated before I put them in the machine!
