This may sound like a big bonehead question but I have to ask as I am hunting down issues with my car for the last 7 months.
I have this leak, I figured I will flush the coolant and do this at the same time and change the oil as well.
I was just curious that since this leaks, could it interfere with engine performance at all? I know with a valve cover leak, you get bad vacuum leaks, I assume the filter housing is pressured and not under vacuum?
Just curiosity, I have small idle glitches here and there.
It is going to the dealer tomorrow to have the fuel system checked cause it feels like the pressure regulator or pump are on the way out.

This housing gasket really does not look that hard to do.
