It is important to add that coil packs tend to fail due to water ingress.
Don't spend a fair amount of cash on new items and overlook the underlying issue.
Damn right. Seal that scuttle.
Clue. Is the foam wet on the scuttle underside? Is the windscreen seal correctly fitted? Hrab the scuttle and pull. If the seal moves away from the screen, remove scuttle and refit seal. It clips on. Etc etc as BM says basickly.
Agreed. Once the windscreen to scuttle seal slips down, the groove fills up with dust and muck washed down off the screen. It then won't grip or fit on the glass so needs removing and cleaning out. By removing the scuttle it tears the foam seal to bulkhead so that then needs mastic sealing.
The windscreen seal was hanging off on one of the cars worked on at the recent meet and the foam was hanging in water. It was clearly dripping on to the coil pack so that needs sealing.
