thermostat gasket leaking

Yes, the only thing that I didn't do was run a Bridgeport end mill over my stuff. Plus, I was just tired of sealer oozing out all over the place with antifreeze. The o-ringed housing with no sealer was the ticket. To each his own.
Good luck.
A piece of glass and sandpaper is all that's needed. A sanding block for the intake. No need for a 10K dollar Bridgeport.
