    No compression
    I have a 2.4L twin overhead cam, the engine does not start, I did a compression test and they were as follows, from battery 156, 0, 165, 175... and It seems that every time I crank the engine I have oil splashing or such at the back of my engine bay...

    Any help or tips would be great thanks.

    I'd say # 1, # 3 and # 4 readings are similar enough.
    Are those dry readings? Try a shot of oil into # 2 and repeat the test for that hole...
    You may have failed headgasket and/or rings in that hole.
    It might just be time for a new motor, or just a little repair.
    Let us know!

    I stuck a thin metal ruler down all plug holes and cranked it several times after about six different measures every piston rod meadured different but the one with no compression.

    That is indeed a unique test you've performed.
    If all the pistons moved except for the # 2, you need a motor.
    Your's might not be able to be fixed, but without disassembly for inspection, you still don't know excactly what happened or why. With "oil splashing at the back," I'd venture a guess and say the engine broke the # 2 connecting rod and crankcase oil is being tossed out the hole.
    Inspect the lower back area of the engine for any obvious damage. Normally such failures will be accompanied by horrendous noises... :eek:
