Yun nga yata... not sure per engine kung ano yung exact... depende rin yata sa ambient pressure. Last time I did this, 110-112 yung engine na na-test namin. Malakas pa yung hatak niya, naninigurado lang ako dahil surplus.

If your engine starts to lose compression from blown piston rings or a leaking gasket, usually, the effect is stronger for cylinders on one side or for one particular cylinder.
