Almost forgot... There is an overlooked common issue! Check the egr tube that goes in under the TB, those are prone to cracking which creates vac leaks. If your not loosing coolant then I doubt the LIM gaskets would be bad enough for a vac leak there. But if you pull it again, don't bother with a supercharger gasket, just use rtv in the pattern of the gasket. Sure you gotta wait for it to dry before you run it but it's cheaper if you have it apart often.
That wasn't staged at all... Just what happen to be on my desk when I came inside pissed and wanting to rant about my lifter to the GTO guys lol.
