    How can you tell if your motor has been bore out? I finally took motor apart and seen the reason why it was shooting smoke. The valves look worn out and burnt oil bad . How can you tell if block is still good and if it has compression.

    You have to measure it.

    Perfect. Is there a particular reason you are asking? What direction are you looking to go?

    I was just checking to see if the block was bored out or not by measuring it .. But im more curious , when I had the motor in my car it ran great until it started throwing out smoke. So I took motor out and finally took heads off and the valves on heads look bad and the head gaskets weren't blown . Also the walls feel smooth and don't look bad but im wondering if the block could still be good, if I were to just put different heads

    It probably is. Good chance the valve seals were just leaking a little bit. If you have good cross hatching on the cylinders, it's probably still good.

    Is it possible if you can post a picture of good cross hatching on cylinders?

    See the cylinders? See the X pattern in each one? That is called a cross hatch. You want to see that in yours.

    The true test is a compression test. If the engine has good comrpession, then you are good to go.

    That would be pretty hard, but if you could pull it off you'd make a mint :nice:
