Re: '78 351M Thermactor, Diverter, and Check Valve
Yeah, definitely not in Cali. I currently don't have a wrench that fits on the fitting with the manifold. And I have no idea how large that fitting is, so that's going to be a challenge plugging it. In the meantime, since the check valve is leaking, seems like the most immediate course of action is to seal the leak with some SteelStik. It's doing a pretty decent job plugging the Thermactor port on the driver side with a partially disintegrated plug stuck in it.
