I posted about my coil issues a while back, (almost 30 days) and i swapped out the first coil on cylinder #1 (4.7L not H.O.) today the new one blew out. I figured the old one was because it was old, for all I know it was still the original from the factory. any ways does any one have any idea what would cause this to happen? This is what it looks like. https://drive.google.com/file/d/12R_...ew?usp=sharing and https://drive.google.com/file/d/12JQ...ew?usp=sharing

I dont want to have to change this out ever month.. I pulled the spark plug and everything looked fine (evidently I put in outlite 5224 plugs at some point.. i don't remember doing that, but if I did it would have been about 3 years ago.) I'm feeling like i should replace them soon just because.

 

Was that a quality coil? I have seen this before when a cheap chinese coil was bought online. Aside from that, I have been told that worn plugs with an excessive gap can cause a coil to fail.

 

It was from Napa ran about 30 bucks. I checked the gap on the plug it was right at 0.044 I'm going to return it tomorrow and hope it doesn't happen again

 

Stick with OEM.

 

It was an echlin I always thought those were decent ones. If it happens again I'll swtich back to OEM..

But I'm now also leaking trans fluid form one of the cooler lines going to the radiator (right at the fitting)

 

Mine has been leaking there since I got it in 2014. Cheaper and easier to seal the driveway every few years . . . .

 

Yea I'm renting lol. but it was enough of a leak that i was watching it drip. I wiped it off and the metal part of the fitting at the tank broke off.. so new radiator. (granted this was a 50$ radiator I got off ebay a couple years ago.) replacing with an OSC 2883 enhanced from rockauto with a lifetime warranty. I'm hoping that maybe the issue with my coil is heat related and a new radiator will solve that also. If it blows another coil I'm done. truck will be sold at that point lol. IF it comes to that, I'm thinking about finding an old carbed GM or Ford from the 70s lol.

 

just an update for one who is interested. I finaly put a new ECU in and it did not help. SO i'm at a loss. gotta be a bad wire or . UGG

 

Thanks for the update. Damn.

 

I've got an idea, i just need to figure out which wires go from the ECU/PCM whatever its correct term is, to the coil, I'm going to splice two new ones from there directly to the new coil and see if it keeps happening. That will rule out a short on those two wires.
