Coil Pack Failure, Again??
On s types the water gets in through the windscreen trough see message below


After months of hassles ... a solution {for my XType}... my local garage says that the problem is moisture getting into the coils ... but ----- HOW was always my question??? It would seem that the "cowling" if that is the right word has deteriorated around the camshaft cover ... a bit like the lip on a cup, above the handle. It's cracked and flattened.
Local garage advises to get a new Camshaft cover, but really ... that is not the solution. The solution I'd have thought would be to remedy the windshield issue ?? Did you ever get a resolution on this properly ???

Could you post the link to the Youtube video you mention ?
Many thanks in advance
The windscreen trough leaks water onto the engine in pre 02 models and causing the coils to go happened to me twice before I was told I found a youtube video of how to fix the leak problem solved 5 quid for a tube of mastic is better than 300 for jaguar coils and plugs
What did you do to solve the problem with repeated coil failure way back when.. I'm having the same problem on a 2004 S-type 4.2L v8. I was doing preventive maintenance replacing the coils and plugs at 87k before 100k and now can't get #8 coil to stop failing. Don't fix something that isn't broken. Help anyone.
