For the charge pipe, you can just change the o-rings. The new style pipes rarely go bad (with stock boost). But the o rings do fail and make a mess. Removing the pipe is not super easy. I removed my inter-cooler to better access. It is then challenging to get the connectors to click back into place. Pull on them to make sure they are fully seated.

I don't think the charge pipe can leak a half a quart over 3 months. But a leaking sensor gasket could. And yes, removing the sensor will require draining the oil.
