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.
