I discussed this with Josh Holder at the NCM showing. Water is going to get into the engine bay through the vents in the cover and the engine is going to get dirty. There is a drain path for water under the vents. The connectors are water tight and the car can be driven in heavy rain. I’ll bet green tree pollen in the spring will find its way into the engine compartment if left outside.

No issues at all, and just like water intrusion in the Huracan engine bay area, the '05/'06 FGT have open vents around the rear clamshell glass, open vents in the front hood, open vents in the rear, wash and dry (any method you like) and you're good to go

Taste has actually responded to this question asked of him and his answer was very precise, he suggested that the engine bay was designed for rain and everyday water intrusion under driving conditions but he stressed that it would be best not to use any pressure washing or jetted sprayer directly over the engine vents and to definitely avoid commercial car washes. This seems to make the most sense regardless. You aren’t going to destroy the engine right away by hosing through the vents. The suggestion was though that it could lead to greater corrosion with time. I personally think that everyone is going to do their own thing.

There is really no more issue with a mid engine getting water in the engine compartment than a front engine. What I do when I wash our mid engine cars is lay a towel (several depending on openings) over the engine and tuck it in so I can close the engine cover over it. Once I am done with the water and blowing off, I open the engine compartment and use that towel for dabbing little areas and doing windows. Makes it quick and easy.

Without the glass you wouldn’t be able to see out the back using the rear view mirror. The side grills on the hatch and the bottom of the hatch glass are open to the elements. It’s going to require keeping the inside of the glass hatch and the glass between the engine and the passenger compartment clean for optimum rearward visibility.

While it's motorcycle cleaner, it won't attack and discolor plastics and such. I have had cars that I prepped for competition concourse events using this.

Considering there are fans in each side cove to blow air through the engine bay, I expect hosing down the engine will be part of normal washing. Imagine being in a semi truck's road grim spray on a rainy day... that's going to get all over, but these engines all use weather-pack electrical connections and are made to be washed.
I do recall a TSB from the C5 days where the knock sensors in the valley cover would corrode from folks who washed their engine bays frequently then didn't go drive and let the engine eat evaporate the water. Water would get under the manifold and into the knock sensor cavities. Knock sensors aren't in the valley anymore so non-issue.
