My F-type is parked outside all the time and I don't have any issue with water ingress.
As your F-Type is the AWD version and you’ve previously said that the bonnet vents are different to the RWD, perhaps this is one of the reasons that you don’t have any issue with water ingress?
With regards to the V6 RWD, water definitely enters through the 'open mesh' bonnet vents (which is normal) but it's getting to places where it shouldn't and is causing issues on some cars e.g. injector corrosion/failure etc.
The attached photos are from Lunar's V6 (which he posted earlier) and they show what the engine bay looks like after the car has been parked outside in the rain (mine is the same). They clearly show where water has entered through the vents (again, this is normal) and drips down onto the plastic engine covers etc.
If, by replacing the 'open mesh' vents with the 'shrouded' ones, it would resolve the water ingress issue on the V6 RWD, that would be great (providing it doesn't have a negative affect on the under bonnet temperature?), but as member GBH has already said that he has them factory fitted on his 66 plate MY17 V6 and they still allow water in, this would be pointless? Perhaps he could elaborate further on the subject?......this would be appreciated.
Although member Tel (V8 owner) has said....."Pointing the hose directly at the 'shrouded' vent at normal mains pressure didn't cause water to enter the engine bay", it would be beneficial if we could have further opinions from both V6 and V8 RWD owners who have the 'shrouded' bonnet vents fitted, to see whether or not they allow any water into the engine compartment e.g. onto the plastic engine covers etc? As far as I understand it, the 'shrouded' vents are exactly the same for the V6 RWD and V8 RWD and as Tel has said, they are interchangeable?
The original poster has 'open mesh' vents fitted on his V6 and he mentions....."Bolts on left bank seized - due to possible pressure washer detergent, freed up / replaced." He also asks the question....."does anyone know if the bonnet louvres can be covered when you wash, is there anything out there to do this?"
In this case I'd say we're still very much on topic as our aim is is to prevent water that enters the bonnet vents from causing unnecessary issues in the engine compartment.
