    M119 Timing Chain and Guides replacement video

    Our friend Victor is doing a chain replacement video series on a '94 S500. Obviously not a step by step guide, but he does have lots of useful information.

    Re: M119 Timing Chain and Guides replacement video

    Very useful videos - hope he posts more showing the re-assembly process.

    Interesting that the driver side stretch was ~2° while passenger side was ~10°. This large of a difference between driver & passenger cams typically indicates the center guide rails are broken. His second video confirmed this, 3 out of 4 "ends" were busted (and 2 of 3 broken ends were missing) for the inner rails in the "V". The rail below the driver exhaust sprocket was grooved pretty well too.

    In this scenario, just changing the rails would likely improve the passenger cam timing dramatically (say, improve from 10° to 4°). If so - I'd have left the chain alone rather than replace it. Even with 10 degrees the engine will run just fine, but the main risk is the broken rails. If the rails totally disintegrate there can be a serious failure shortly afterwards as the chain runs against the metal pins.

    The camshafts do not need to be removed, however with cams in place the cam advance mechanism has to be removed from the intake cams, which is not fun without the special tool. I find it easier to take apart the adjusters rather than pull the camshafts, but if you would rather pull cams, fine. I'd definitely not remove the exhaust cams, the sprocket is attached with 3 bolts and is keyed so you can't mess that up. There is no need to remove the exhaust cams.

    I was glad to see that he only used the clip-type mater link temporarily, and plans to buy the proper crimp tool and use a factory crimp link. Side note... aftermarket crimp links have a slip-fit outer plate; the OE factory link has a press-fit outer plate. The press-fit is additional insurance in case the crimps were not perfect.

    With the whole front of the engine off, I'd highly recommend replacing the front crank seal too, if possible. In video #3 (at 2:21) you can see it appears dry, and also may have been replaced in the past as it's set inward several millimeters. (??)

    Last comment: With chunks of rail broken off, they had to go somewhere. First check inside the timing cover with a flashlight and fish out any pieces you can find. Then you MUST drop the oil pan to remove all the shredded pieces of plastic, which can plug the oil pump inlet screen. Maybe he'll cover than in a future video.

    Dave - The chain was replaced by another at a previous time, as indicated by video 1 and 2. (at least that's how I remember it)


    I claim a Roger Clemmons, misremembering. at 8:03 in first video, he says "he" will replace chain.

    Louis, I didn't catch that part - I thought it was the original chain he replaced.

    If it was already replaced once before, it really did not need to be replaced again.

    He said at 8:30 he was going to silicone the front head covers on... hope that was an early-morning mistake and he didn't mean silicone.

    Perhaps it was the anaerobic sealant since he pointed to both cam shafts that needed it.

    Anaerobic would be the correct stuff to use, but he clearly said "silicone". I'm still hoping the coffee hadn't kicked in yet.

    I think that loose bolt at the end is one of the water pump bolts that needed to be torqued to 21nm.
