Weird things happening is what I do best! I believe it is an S5 pump but with that said, I had 2 washer/shims about 2mm thick that came from 2 of the bolts that went into the block that were between the pump and block. But it also looks to me like someone has ground away at parts of the pump so anything is possible at this point....
I will check, I think I took pics of the block when it was all apart so might have pics of the shims.
The deeper I look the more I seem to find from previous owners messing around with the poor car.
On the plus side, I cut a new gasket last night, blotted it all up and .... NO LEAKS!!!
I have come to realize this RX7 has had a MUCH harder life than I believed it had....
