I seem to have recently lost that rubber stopper that’s in the ficm. I noticed it tonight taking things apart to get to my valve cover. Anyone know the part number for this thing or have any diy solutions for it if it only comes with the ficm? Not sure why these pictures got upside down but I think it had a rubber nipple in there I guess to keep water out but I don’t know it’s original purpose. No problems with the function of the ficm so far.
