Did you check clearances before assembling? (Plastigage the bearing mating areas when torqued down to spec)
Sorry for all the questions, just want to understand your build. Maybe more questions to follow depending on the answers.
Its a used EJ257
I ordered stock bore size pistons, i did not check for clearances though. I didn't think i would have to since the pisons should be the same size right?
