Don‘t see the exact crack here , can you clean it and re post a picture ?

Ill run back out there in a couple mins. Heres another pic

Its near the DP sensor on the back side of the block

 

[Chris1113]

Well maybe its the inlets

 

[Chris1113]

Phew Its just the inlet. Just double checked

Maybe there was dirt in the hole when the socket head cap screw was threaded in. Have seen before.

Doing a where used search , that main control valve part # 4304717 is unique to an EX100-2 .
So we now know you have an EX100-2 with serial # 31115 and above .
See parts screenshot below.

This is the PVC model number I need to get then. Good find

All we know is the serial # is above 31115.
Could be pvc part # 9116366 also.
If the suppliers are only offering a generic “EX100-2“ PVC, the serial # I don’t believe is that critical. I think the only thing that matters at this point is knowing 100% that you have an EX100-2.
