  1. RS415 engine compression loss

    2004+ Swift
    G'day. I have a 2007 Suzuki Swift. It has done approximately 260,000 KM's so far. I have compression tested all cylinders and they all 100 psi. Some people are telling me Thy should be at least around 150 psi. Should I be worried? What could be the cause of compression psi loss? Even though...
