I bought the car and have nearly got the ej22t reassembled. I found the aftermarket oil pump had the screws back out of the plate that holds the oil drive gear in and it bled off oil pressure, ate up the bearing on #2 rod. I picked up a new crank & rods. I had considered swapping on dohc heads but im not looking to make a ton of power with this car so the heads should suffice for the time being.
