    Asthmatic B18ft coughs up a piston!!

    Did wonder why the oil tried to exist the engine though the breather on boost!!

    Stripped down the track clio today to find this:









    Got a nice go faster stripe down cylinder No1.

    Broken piston was in No2. No3 piston has some major det marks on the side of it. ( Wasn't Me - previous owner causing this with stupid boost, i never checked bottom end until now )

    I did a compression test on the engine before i stripped it down, all cylinders read about 140 psi. I just thought the rings was lunched

    Now where do i go from here?? I have a spare engine that i can rob a piston or 2 out of.

    I was planning to glaze bust the cylinders, re ring and rebuild it.

    Did you just hone the cylinder and bang in another piston with new rings?
