Oil cooler leak help needed

Also check to make sure you have the right size threaded fittings going into the sandwhich plate... they shouldn't be moving as you had previously mentioned... did you use any thread sealant? I used teflon liquid sealant (sparingly) on all the fittings.

I'm not quite sure what piston you're referring to; do you mean the hexagonal piece on the southern tip of the mocal plate?

I didn't use any sealant. The kit kinda comes somewhat preassembled - the fittings were already on the mocal plate with the washers. Following the instructions, you just tighten the fittings. Also, the leak isn't coming from the fittings. This picture was taken while the engine was off (with the leak occurring much slower) and looking at it again, I guess you can't really see the oil by the mocal name engraving - but this is where I think the leak is originating from.
I got an RMA from Z1 for the mocal plate so hopefully the new one does the trick and Z1 can find out what's wrong with the 1st one.

yes inside the hexagonal piece is the brass plunger that controls the flow of oil through the cooler via the spring.

That part is the actual "thermostat", hence why I referred to it is the end of the thermostat... without that part it is just a standard sandwich plate that is always fully open.
