    Does anyone know if the special camshaft tools for the S54 can be used on the S50B32 as well?

    When looking at the specifications of some of the aftermarket S54 tools the S50 is said to be compatible, but I'm not sure if that's truly the case.

    The reason why I ask is because S54 tool seems to be more readily available, both the oem tool and aftermarket versions.

    BMW TIS refers to the same tools for both and these sets are often listed for S50 and S54. On some specific sprocket turning tool or something that's often included is S54 specific afaik.

    @MParallel

    Thanks for the info, I borrowed the S54 tool and it seems to do the job.
    I guess the S50 tool would probably sit more nicely as the S54 tool isn't wide enough to clear the "ears" that are for the valve cover screws, and not narrow enough to sit fully on the valve cover mating surface.

    With the tool I still haven't been able to get the timing 100% spot on even after going through the whole procedure a few times, the timing seems to be fine but after I turn the engine a whole round back to TDC the timing is a bit off.
    Could it be because I'm not using the proper crankshaft locking pin? I didn't think it was crucial for the crankshaft locking pin on the exact mllimeter. I'm using some pin I had laying around as I wasn't able to borrow one and they are on backorder at bmw.

    Any chance someone here has the dimensions of the crankshaft locking pin? I might try to grind down a bolt or something to make myself one.

    Hmm strange. If it’s the same tool (bridge) it should fit both engine. Although ebay sets are not class 1 quality, a least basic dimensions should be the same.

    When you set timing and you turn the crank back to TDC and the Vanos is in place, it shouldn’t be possible timing is changed. You would need to have a big chain slack.

    You did turn the engine over twice?
