I know the question here's been entirely answered, but I got a related prob and thought this would be OK.
So I picked up one of MikesXS starter delete kit. I know, I know the freeze plug's out there, but I figured I would see how this one fit.... Well I don't know if the the thing's out of speck but the thickness when screwed together is larger than the thickness of the case wall. So this "kit" just slops around there, and wouldn't hold oil back if it tried.
Wanted to see if anyone else had this problem? Did you have to use a gasket to make it work. Really just feeling like is just a POS...and the freeze plug would fit better anyway. Paper weight maybe?
