Hi all a little help please for a silly problem.

I keep getting water in the coils and I have seen with my own eyes the rain water running behind the windscreen rubber that seals it between the cowl / scuttle panel.

In an attempt to fix this I loosened all the torx nuts and pushed the cowl / scuttle panel up as far as I could while someone re tightened the screws. The result is the rubber seal overlaps the windscreen by maybe 1-2mm more.

I've yet to find out if this fixes the problem but I'm not very optimistic.

I've searched the problem and seem jaguar issued a sticky tape fix for the S type R. But this is not the same problem as its affecting my coils not my throttle position sensor.

Somebody must have a decent fix out there?
Maybe I could peel the rubber back where it overlaps the windscreen and apply done rtv silicone I side it and then push the rubber seal back on the screen?
I can't see any major issues with this especially if I only apply the silicone where I have seen the water dripping into the engine bay.

Help will be greatly appreciated.

Thanks Rick.
I have seen this before but I wondered

1. Do you let the silicone dry before re-installing the cowl or do you push cowl onto the wet/drying silicone?

2. Does it make life Arkward when or if the cowl needs to be removed. Example for service work or changing cabin filter.

Darren.

 

I asked the same thing in the thread that Rick linked too.

Eds123 explained that he let the silicone dry before re-assembling the panel.

 

I think someone put RTV (*) then cling film and then put cowl fully on. Idea is that it shapes properly but later will come apart readily due to the cling film.

(*) any setting sealant should do

 

Someone attempting the fix could always apply the silicone RTV to one surface, then spray WD40 on the other surface before setting the piece in place. The WD40 will keep the silicone from adhering, but allow the silicone to form properly.

 

Plums will that work?

One thing I'm really struggling to understand is how did the s type pass any tests when it was originally designed and made. ? Surely it would have misfired when the soaked it with water at the factory?

And do jaguar acknowledge this fault. I know they sent out a service bulletin for the R. But it's a different problem just very similar.

 

They don't leak when new. They don't all leak when years old.

I think some leak when people bend the cowl to change the cabin filter. Something like that. And some just decide to leak.

 

Uh oh is this a stab?

 

Not meant to be. Maybe I have it wrong?

 

Jagv8 thanks. That is thd most plausible reason I have heard off as to why these leak.

Makes a lot of sense.

 

another possibility is the rubber just deteriorates over time and becomes "loose", allowing water in, after all some of these cars are 13 years old now, i don't know about you but i don't think i own anything else as old as that.

 

Main thing is to reseal it. A bit fiddly but very worthwhile. Otherwise depending on luck and car model you can get water in the PCM, the plug wells (damaging coils), the TB (throttle body), or.. er I think that's the list.
