    valve leak?

    Hi! Have you ever encountered an engine valve leak? My engine valve always leaks. It will leak after running in for a while. If the valve is lubricated, he will leak a little. 45 # steel was used for my valve and it was simply quenched. How can I solve this problem? Thank you

    Hi Edi! I suggest you put the O-ring in the second ring, so that the O-ring can get enough lubrication, reduce friction and improve service life.

    Micro distributor leakage

    Thank you. I reduced the electrode to 1mm and the pointer to 1mm according to your instructions. There is no leakage now. Thank you. Later, I'll send up pictures of my distributor.
