    Hi all,

    I have a 2000 3.2 dohc rodeo that had a broken timing belt. The cause was the timing sproet for the drivers side cams seized, because it seized i couldn't line the mars up prior to pulling it apart.
    Now i have the new carrier installed and new timing belt etc i now need to now how to line up the cams to match the drive sprocket.

    Does anyone have a diagram that they can post so that i can finish this job?

    I did google it but couldn't find a clear enough diagram.

    Any help appreciated.

    Cheers Shane

    These things are a piece of piss

    You will find timing notches in the timing belt gears on the cams, D/S should be rotated till the notches line up with the head, the marks on the timing belt should line up as well
    You will need to preload the O/S cam with a 12mm socket & breaker bar when you fit the belt.

    I can take a pic of the front of a engine to show the timing marks if you need them.

    Also they are an interference engine so have you made sure you havent bent valves or put speed holes in pistons?

    every thing i have read says they aren't a interference engine. Just need to know where to line up the marks(am pretty sure its the marks on the rocker covers) and if i use the scribe type marks or the notches(i think the scribe type marks). Also need to know how to line up the cams as i have had the drivers side ones out. I will probably have to take the passengers side rocker cover off to see how they line up.

    Cheers Shane

    I put this thing back together with the help of the genuine manual. It is running only on the left bank, i have checked all timing,the injectors are pulsing and have checked they are letting fuel out and have changed the plugs and coils to the other bank to check them and i have spark at the plugs. It has good compression and i have checked that the timing marks are in the correct spots. The only thing i can think is possibly wrong is that one of the timing marks is incorrect.
    The timing belt i was provided isn't a genuine one and does not have marks on it to line up with the marks on the pulleys. Does anyone have access to a genuine belt that can count the teeth between the marks or does anyone know how many teeth are between the marks so that i can mark this belt to check the timing that way?

    Cheers Shane

    After leaving this job on hold and not touching it for a while i decided to check everything again today. When i pulled the rocker cover off to check the cam timing i couldnt see the marks on the cams so i pulled the inlet one out, when i undid the retainer bolts the cam popped up like it had pressure on it. I cleaned the oil off it and re-marked the dot and put it back in. When i did so i thought that it didnt go back in the same way i had just pulled it out. So i cleaned the exhaust cam and it looked like the mark was about 180 degree out, so i put it back in with the mark lined up. It kicked over and now goes properly.
    The only thing i can think that the problem was now that is the cam drive cog turns twice compared to the engines four strokes and not once like i had thought, and every time that i had checked the marks(more than twenty times) it happened to be on the other stroke and that caused the valves to be opening on the wrong stroke, which gave everything diagnostically correct(ie compression, spark, fuel) just that the valves were opening on the wrong stroke.

    This is one reason why you(or me)should do a job when the car isnt going at all to start with.
