Aren’t 1 and 4 fired by the same side of the trigger points too? Would it be worth having a look at those or perhaps trying a different pair? As of now, I’m pretty sure we’ve been through all the brains at our disposal and each has been associated with one or another of our issues…..though it remains to be seen if the brains were at fault or simply happen to have been installed while a fleeting issue was at work in the system.

Yeah, I used a socket with a built in U-joint. I’ll just toss it. Would a thread chaser be worth trying?
