i swear, must be something about this house, the damn things multiply!! it happened with the wagon, it happened with the bmw, now its happening with sisters car...
her boyfriend bought the calais last monday, drove it home from melbourne, went fine, then around town it overheated, fan wasnt kicking in, he bought it to our place to have a look at, and the motor seized in the driveway!!
so dad ripped sisters old motor apart to see what the metallic knocking was(this is why we replaced it with lowagz v1.0's motor). turned out the balance shaft bearing was rusty and worn, making the noise.
so the balance shaft is now removed, and its got a few new gaskets, and is going in the calais.
