exhaust manifold metallic flange replacement

  • Hi,


    I was having a small exhaust leak from cylinder 1. I did a lot of work, cause i had also to remove the power steering pump, and took me many hours to do it properly.


    The pro-cat was missing inside, nothing, empty. inside you can see the lambda sensor.



    see youself


    1st cylinder exhaust valves


    2nd cylinder exhaust valves


    3rd cylinder exhaust valves


    4th cylinder exhaust valves


    My motor is working for 55000 km with LPG so the white color of the valves.


    see my video

  • maybe the LPG doesn´t pays off? ;)


    how did you detect the leaking valve? power loss? exhaust gas? noise?


    maybe, the second kat is emty too. i changed it for better car tax, and mine was.

  • i just had a small noise, from engine, morning start, after 1 minute was over, but now that i changed it, no more noise.


    Also , till today i have no exhaust valve leak, otherwise i morning start would be difficult.

  • ah ok, my fault! didn´t get it right.

  • for everybody to help,


    The metal exhaust flange was bad cause spark plug cables was not in good condition.
    The cylinder near Crankshaft position sensor, had the exhaust leak and noise.
    It was cause by misfiring ignition at that cylinder, which was cause by slack ignition spark cable pipe to spark-plug fit.


    I was spraying during night water to the cables to see if i have electric leak, but no signs.


    So i replaced them just by the feeling, and it was 100% best thing i did.


    Now LPG working perfect.


    Also i installed a new CPS, again, bought it discount original 85 euros.


    Motor is in best ever condition, i never felt my motor so good.
