    My cars exhaust, I just noticed that its making a wierd sound.
    I opened the hood and it sounds like that exhaust manifold has a leak.

    what do you guys think? I made a video check it out

    hard to tell. look at it during the day. look in between the exhuast manifold and the block itself. if its leaking form there u should be able to see it, and smell it. happened to mine last winter. so i got a copper exhuast manifold gasket. now its good.

    yea, but if the exhaust manifold itself starts to leak shouldn't it show an ecu error on your dash??(considering there is a drop in pressure in your exhaust manifold..the exhaust gas sensor should be giving abnormal feedback to the ecu), what about the gasket mating the manifold to the turbo?

    If you are unsure whether the car exhaust problem is genuine or not, start the car and check the questionable area again. You can likely spot exhaust coming out of the crack or leak, which obviously indicates problems.

    hi nick,

    thanks for the info.
    I fixed the car already and its has been sold.
    It was the exhaust manifold and the turbo gaskets that were burnt. Its quiet obvious to blow up those gaskets since its a turbo skyline

    thanks again :)
