Check for and prevention of rust on Ducato injectors.

Thought they'd cured it on the X290 , but not if you don't keep the drains clean. The X250 was terrible, they joined the 2 piece plastic windscreen scuttle with foam 🤔, so water will drip into the engine bay and pool in the injectors

That's not quite correct.

My 2007 X250 with the 3 litre engine has a cover over the injectors so any water ingress runs down the cover and onto the throttle body!

This causes the throttle body to fail in due course as it did on mine. After the throttle body was replaced the cover was extended past the throttle body to prevent a recurrence.

My 2011 one has a cover too, 2.3l and water ingress caused the throttle body actuator to fail too, a bit before yours failed I believe. A bit of job for me to replace. Water also runs into the injectors well too sadly on mine. What is the extended cover you have?
I have seen a 3D printed 'spout' on ebay that fits under the skuttle joint to deflect water drops.

It's very basic. A suitably sized piece of flexible plastic sheet that's attached to the front edge of the existing shield. It's bolted through and underlaps the existing cover.
 
I believe copper grease promotes corrosion on aluminium. I think Duralac would be a better choice. Duralac is a highly effective jointing compound which prevents electrolytic corrosion between dissimilar metals. YMMV
 
just a small point here: don’t use copper on alloy as it corrodes it which will somewhat defeat the object (y) ACF-50 or similar corrosion inhibitor would be better.
PS, just noticed vintageb3 had already mentioned this.
 
Why can't Fiat just design a simple and effective Scuttle panel, a simple cage over the holes too would help stop leaves going down and you could see if the were blocked but water would still pass, similar to what we have on domestic guttering if you have trees nearby.

At least these have three drain holes instead of the one on the early models and on the wrong side too.

Heaven is where the Germans do the engineering, the French do the wine, and the Italians do the cuisine; Hell is where the Italians do the wine, the Germans do the cuisine. and the French do the engineering [and the Greeks and the Portuguese share the driving] :rolleyes:
