Put in four full cans of r134 and now have a 60 degree AC versus a 90 degree AC.
Much nicer now, albeit towards the end of summer, but fortunately Texas won't get cool for another month or two.

Sucks. Any idea what it is yet?
No idea. My son was actually with me. He said sounded like a possible valve tap. Possible clogged hole in a pushrod. I asked him what he thought about Sea Foam. He said give it a shot, might unclog the hole. Idk tho.

Are you sure an exhaust bolt didn’t just pop or header gasket blew a hole? It sounds very similar to lifter tick.
