    Oversize bearings

    DOES ANYONE KNOW IF OR WHERE YOU CAN PURCHASE ANY OVERSIZE BIG END AND MAIN BEARINGS FOR AN RXP '04 BLOCK. ALSO HAS ANYONE HAD ISSUES WITH EXCESSIVE THRUST ON THE CRANKSHAFT. HAVE AN ENGINE THAT HAS SUFFERED DAMAGE TO CRANKSHAFT THRUST FACE AND BLOCK.

    there are bmw 3 series bearings that can be used when machining the crank.
    if the prop has come loose at some stage it forces the driveshaft forward and damages the thrust surfaces

    The motor was freshly rebuilt about 5hrs ago and everthing was checked and rechecked. Am running a stage 3 riva kit running at 13 psi. Was doing an oil change and noticed metal all through the filter. Pulled the engine down and no2 main and no3 big end bearings have been hammered. Also after closer inspection the thrust washer had been cutting into the block and crank. Spoke to a few people down here in Aus and nobody has ever heard of this happening. Have another block and crank but both cranks are a little damaged could probably get away with one of them but was hoping to be able to machine them?
