I think the photo is parts of an old tee seal and maybe a very battered lash cap. Why they are in there a bit of a mystery because seals look all intact and good and not leaking, but most importantly, its not solving my noise problem.
I dug through some old tools and found a 2 foot old screw driver with about a 3/4" blade on it.... carefully ground and filed the tip so it was a 'hammer in' fit to that slot on PRValve, put a big shifter on it and put huge force on it before it popped out of slot..... has twisted the end of this huge screw driver. Then i filed up a cold chisel to catch in the slot and hit the end with a big hammer......still not shifting. All I can think of now is hiring an oxy torch! I guess i could drill a hole in it and try an easy out, but I reckon it will just rip the guts out of the brass fitting if it is bending huge screw drivers. I guess I could dremel away the perimeter of it to make it thinner and then try again. I am sure it is that the amount of surface area, right around the perimeter, is what is making it so hard to shift. There is a lot of surface area in the threads too, but i think brass into aluminium and it wont be seized. So my thinking is that if I grind away enough of that perimeter so it releases that pressure on the edge, I might have a better chance of cracking it. There were zero marks on it before i started, so i think it is the original one. Car had done 220k km so you wouldn't think it would have needed to be touched, but then you wouldn't think it would go wrong either. As always, any suggestions or comments welcome.
