Dartin for Divorce

Getting old fittings out of an intake:
1.Heat the fitting up red hot.
2.Put paraffin wax on the fitting so the wax melts into the threads.
3.Now smack the fitting with a big ******* hammer. This "Shocks" the fitting.
4.Clamp down on the fitting with some vise grips, and twist it off.

PS: No need to drill a water neck. You already have a hole for a temp sensor.
