    Default Need Help: Daewoo Cielo camshaft broken three times

    Good day all,

    I've been facing this problem from almost four months, first time I had my camshaft broken, then when I replaced it it worked for about a month and it has been broken again. Replaced it again with making full engine repair (valves, pistons, oil pump) drove the car for 500 km and today when I started the engine and about 2 minutes the engine stopped!. the camshaft has been broken again.

    In the three times the break is at the exact point!!

    Please help what would the problem be?

    Best regards,

    Put on steel boots, Goto the workshop kick the person under belt twice. make sure his reproductive system become a tube for bladder cleaning only -

    The engine is from OPEL /GM family and camshaft damage is possible for few reasons i can assume, - bad oil pump / sludge in crankcase and or wrong timing belt. once seems bad maintenance, 2nd & 3rd failure is sabotage or surely IDIOT carpenter acting as motor mechanic

    Please share more details of damage

    if its the original SOHC TBI engine then I salute you for killing it, I have tortured the living daylights out of that engine and it still was running sweetly.

    The only reason the cam can sieze is from wrong bearing journals or severely warped head which has been faced straight on the deck side only.

    When a head warps the whole casting bends in a n shape the cam alignment is completely jacked if the warpage is very high. The cam carrier on your engine is bolted separate to the head, did the mechanic test it for free movement without valves installed? Its standard practice on that opel engine.

    free floating test of crank shaft is a must and it is the job of machinist ... anyone can fit engine parts but only the free floating test tells u how it has been assembled

    In this case the cam carrier is bolted on top of the cylinder head, I suspect the head is actually bent out of shape or the carrier pedestals are damaged in some way. Causing the bind, Yes - you are completely right in saying that the mechanic should have confirmed the free float test before starting the install.

    Thank you all for your replies,
    One thing I forgot to tell that the last time I have changed both the cam and the casing, and the mechanic told me that will be enough and it won't break again!!

    Another problem is that I live in Syria, so the spare parts are very difficult to bring. What would you suggest if I want to buy a new engine for my car, is there any other engine rather than the original one can fit to my car? Or do I have to buy a new cam and casing?

    One more thing, if the timing is not correct, does the engine makes noises or vibrates or something else?

    Sorry for my questions but I'm really having lots of troubles with my car specially after spending about 1000 USD on it in the last month!!!
