My only reason for suggesting that he change the UIM altogether, along w/ blocking the ports was the fact that he will be removing it to do the LIM gaskets, and that UIM has 220K on it. It may decide to crack when he bolts it back down again, and then has to deal w/ a vac leak like I did when I tried an old UIM that cracked in this fashion.

But hey, if it ain't broke, don't fix it
