I will be purchasing a Husky 372XPGW, with X torq, soon. I noticed that the transfer ports seem to have a removable cover/plate over top. The screws that hold the cover on have a similar head to that of a torx head, just with a dot in the centre. Like a tamper proof screw ya know? The salesman told me to never take that cover off because there is a seal in there that wont properly seal once it has been removed and then put back in again, hence the anti tamper screws. My questions are: Why do the transfer ports need a removable cover at all? It seems like another potential spot for air leakage in the long term. And why don't other 372's have this? I could be wrong, but I swear that I've seen some 372's that don't have this...? Thanks for the insight!
