Common issue, usually get an engine mgt warning on dash which indicates trouble or you can feel it misfire or you lose a bit of power and as you say usually only in the rain Link to comment Share on other sites More sharing options...
Berni29 Posted May 19, 2020 Report Share Posted May 19, 2020 Hi I wonder what the issue with running theses is if there is no misfire? I have changed a couple of cracked ones recently also, but I guess maybe a coating of spray grease or waxy rust preventative such as Dinitrol or Tectyl would have kept any water ingress at bay?

½cwt Posted May 19, 2020 Report Share Posted May 19, 2020 If you know they are cracked, best to change them as they will eventually get moisture inside and cause a misfire and if you don't know they are cracked, leave them. Also a set new is not a huge amount of money rather than doing it piecemeal as each one cracks/fails. The misfiring will only occur when they can't give the voltage step required to fire the spark due to damage or moisture inside the coil. Link to comment Share on other sites More sharing options...
JohnnyUK Posted May 19, 2020 Report Share Posted May 19, 2020 Swapped mine a couple of years ago because of a sudden misfire...some were the originals with a 2000 date stamp on them! 😊👍🙄 Link to comment Share on other sites More sharing options...
red rocket Posted May 19, 2020 Report Share Posted May 19, 2020 I had new coil packs last year when a couple were found to be cracked during service. Had no inkling of any issues beforehand. Link to comment Share on other sites More sharing options...
ThreeSheds Posted May 19, 2020 Author Report Share Posted May 19, 2020 I would say that the plugs are fairly new so whoever changed them last must have seen the state of the coilpacks and did nothing about it...... Link to comment Share on other sites More sharing options...

Mr96er Posted May 19, 2020 Report Share Posted May 19, 2020 Did mine a couple of years ago when I first got her. Wondering if they should be looked at again. Had an occasional misfire, usually when switching from 99 - 95 Ron and back again... anyone else experienced that? Link to comment Share on other sites More sharing options...
el 3.2S Posted May 19, 2020 Report Share Posted May 19, 2020 I have never looked closely at the coil packs on my car. Have never had a misfire, so no real reason to look. No mention in the papers of them ever having been changed? Wonder if they are the originals from 20 years ago, could this be possible? Link to comment Share on other sites More sharing options...
topradio Posted May 20, 2020 Report Share Posted May 20, 2020 Changed mine a couple of years ago, they were original 2 decades old and all had cracks to some extent, no misfire though. I fitted BERU from ECP and they were the newer, larger style and were supplied with longer mounting bolts. Good price as well. BTW, I sold the old ones on eBay and somebody in Germany bought them!

That is good to hear that they can survive and still function correctly for so long! Even better that they can still be sold on at such a late stage in their life!

topradio Posted May 20, 2020 Report Share Posted May 20, 2020 I'm constantly amazed that such things have a value to somebody. However on a practical level, they still worked and the guy got 6 for less than the price of one new one. Link to comment Share on other sites More sharing options...

pipsqueak Posted May 20, 2020 Report Share Posted May 20, 2020 Fitted new coils last July as a precaution and will probably change the spark plugs in the autumn as they'll be four years old but only 12k miles of use. Link to comment Share on other sites More sharing options...

RickLS7 Posted May 20, 2020 Report Share Posted May 20, 2020 If you fill the coil cracks with black silicone, you can get a couple more years of reliable running. Link to comment Share on other sites More sharing options...

I would think that's entirely possible, especially with a low mileage car... mine is 16 years old and done 55000 mile and I reckon mine are original...

RickLS7 Posted May 25, 2020 Report Share Posted May 25, 2020 If you don't mind your specialist telling you there's white silicone all over your coils when you take it for a service - go for it. Link to comment Share on other sites More sharing options...
