  • How Not To Port & Polish Your Cylinder Haed!!

    Guys, the below post was taken from a Mazda forum a guy at work is involved with. Surley this is a hoax?? Maybe not if there soft enough to be keen on standard Jap Cr@p!



    Hey guys, I've got a 96 BA 1.8. I've had an induction kit, exhaust and
    chip for a while and wanted to get more performance. I was recommended
    to port and polish the intake and exhaust. We found out they used
    abrasive material to do it like gritty sand. So I got with my friend
    that tunes Hondas and we decided to try it ourselves. We got a bag of
    sandblasting sand and hooked up into the intake and started the car. We
    had to hold the gas so it would run. He wanted to let the engine suck in
    the sand through the intake so it would port it out and then push it out
    the exhaust so it would port the exhaust manifold.

    I was worried that it might cause problems but he figured it'd be OK as
    long as we didn't rev it too hard. After running the car and letting it
    suck in sand we got about half way through a 25 lb bag. The check engine
    light was on and the engine was bucking and kicking and sounding really
    weird. We stopped and hooked the car back up normal and took off the
    sand supply. We tried to start it again and it was really hard. Once
    started it couldn't idle and kept making weird noises. We took it out
    and drove it and it started to make scraping and knocking noises.
    Help! Can anyone tell me what to do! My buddy only does Hondas so he
    doesn't know much about Mazdas.


    Really, so could this be the end?

    I was thinking what if i got the engine running and poured a little
    water in the intake, could that flush it out?

                I'm sure it is but having said that I've met a mechanic who fitted brake pads the wrong way around (metal to the disc!) on a customers car and another mechanic who forgot to do wheel bolts up, so if thats possible then two Mazda twits could have done this I guess...
