    Default Snapped exhaust manifold/turbo stud snapped in cylinder head!

    1.9 150 z19dth engine. 81,000 miles.

    Has anybody had this problem before? I havent had time to strip down the whole front end of the car yet, looks like its snapped flush in the cylinder head.

    Anybody heard of this problem before?

    I snapped a stud on an old astra gte when fitting s SS manifold years back. New gasket and fitted the manifold, no leaks
    Now I need a turbo to keep up!

    i wasn't fitting a new manifold/turbo tho.
    Will need a new stud as its leaking and making a weird whisteling noise.

    May invest in a set of left hand 5% cobalt drill bits and a helicoil kit if the job turns into a complete disaster.

    Just use an ordinary drill bit, if the stud snapped because its seized, drilling left wont make any difference if you might be thinking it will turn out/undo whilst drilling it with a left hand drill bit, also they are only mild steel and don't take much drilling.

    An easy out might be an option for you.

    If it goes badly what ever way you do it, use "T-serts" or Time Serts, Wurth UK stock them, rather than heli-coils.

    Good luck.

    The stud snapped when i was driving it, the turbo has never been off the car (well at least for the last 30,000 miles i've owned it.) So i'm not sure if it is seized or not?

    Used left hand drill bits and lots of penetrating oil to remove the snapped stud, fitted 8 new studs and new gaskets

    Just incase anybody else has this problem.

    Well done

    Not sure I've ever come across "snapped for no reason" exhaust studs before though on a standard engine !!

    Keep an eye on it

    It does have a crd-t fitted so I suppose the extra heat may have caused the stud to fail.

    It seems to be common on r33 skyline engines, even when standard.
