Time for another modification to the turbo install!

Here's the wastegate:

It's right behind the radiator fan, a bit below the half-way point of the radiator/fan. Inside the yellow circle is a filtered breather cap, which allows air in/out as the wastegate diaphragm/valve moves. This is the wastegate's atmospheric pressure reference.

Notice all the mud! That's from splashing through some shallow mud (6" deep at most) and some shallow puddles. Clearly, water/mud is able to easily splash up onto the wastegate, and I don't want water/mud getting into the breather port. Especially if I ever end up in water deep enough for the wastegate to get submerged.

So time for a breather hose! I got an extra barbed hose fitting. It's the same fitting used to connect boost/vacuum lines to the wastegate and BOV in the stage 2 kit:

There's not really enough room to simply replace the filtered breather cap with the barbed hose fitting (too close to radiator fan shroud). Luckily, there's an optional breather port on the side of the wastegate. Look back at the first picture, and you'll see the plugged port just to the right of the circled breather.

Here's the plug and filter removed:

You can see that the filter already has some mud in it!

And here's the final result, with the hose fitting on the side, and the plug in the front:

That's 7/32" vacuum hose from a local auto parts store. From there, it meets up with and is zip tied to the radiator fan's wiring:

The end is curved to point downward, tucked behind a radiator fan mount. The end of the hose is at the same level as the turbo itself (and therefore, the air intake), so if I'm ever in water that deep, I have much bigger problems than water in my wastegate.

Doing this with everything already installed was pretty challenging because of the tight spaces. My hands are scraped up. It would be much easier to setup the wastegate this way before installing the turbo kit.
