    hey... I have had a rocker arm broken.. first piston. admission. which one is yours?

    1) either the oil ramp problem.

    2) either engine reved too high for too long. I know,,, you have an automatic, but so do I and a BMW specialist managed to break my engine.. I think he drived in 123 mode. since then I give mechanics the middle finger. I do everything myself now.

    I think you would better rebuilt your head altogether. less hassle. cheap if you do it yourself. check the belts and water pump and off you go. removing the rocker shaft is a pain in the ass without removing the head. besides the shaft is probably bent. (so was mine)

    in the stealer around $10-12 per hour. but i never go to the stealer. Outside its cheaper. A friend had his tranny rebuild (535iA) for 25,000 pesos or $470-$500 parts and labor.
