    Timing Chain Tensioner Spring Replacement for i6

    So, after 8 years and reading some pretty nasty stories about the cousin v8 chain tensioner and related guide rails, I decided to change the spring of the chain tensioner.



    You need the coil spring p/n 11411706809 and the aluminum crush washer p/n 07119963418 (gasket ring).
    The procedure is trivial at best. I did it while doing the oil change. The Chain tensioner is located on the passenger side, in front of the engine behind the air check valve:



    Stuff some paper towel and rags - there are electrical wires underneath, and oil will come out:



    You need a 32mm socket or a 1 1/4" socket. They will both fit. The tensioner is at an angle, and you might not be able to remove it with a straight extension (a wrench "might" work, but bear in mind you deal with aluminum here), so here is what I used:



    Out it comes:







    The gasket might get stuck on the engine. Make sure you don't leave it there.
    Here is a side-by-side of the old vs the new spring. You can see the old one is slightly compressed:



    Buttoned everything up, and tightened it with 25 Nm. EDIT: tightening torque for M54 engines is 70 Nm as per TIS
    After starting the car, the assembly will need to be filled with engine oil. I was actually amazed how quiet the car is now. As mentioned, I had no codes and no driveability issues, but the car sure sounds like new now!!!

    Great news! Or is it placebo effect? JK. Thanks Doru, I will be doing both mine and the wife's next week, if the parts ever get here from Autohaus of AZ.

    So all you need to replace is the spring and washer?

    It comes as a complete unit. He just took it apart to show what the guts look like. I did this and the upper tensioner on my E36 M3 when I rebuilt the VANOS. It really is as simple as it looks.

    Are you sure? The spring listed as a separate part and can be ordered as such.

    That's all I did. I posted the p/n also to make sure it's clear. You don't need anything else.

    I've never seen a thread where the tensioner failed on the 6-cylinders. Not saying it isn't good to do preventive maintenance, but...

    It must be available both ways. I ordered part #11317838675 which is the complete assembly.

    Yes it has failed, however, these I6s are not interference engines and when the tensioner fails normally it just snaps and you have to tow the car. Not "my engine is destroyed" as in M62s.

    This is what is listed at realoem.com with that part #. Are you sure it is for E39s?? From the picture it also looks substantially different. I think you ordered the wrong part pal:

    A failed tensioner won't destroy an M62, my tensioner failed in the compressed state and was barely noticeable. I think m62's only have a problem if it's left in place for extended periods of time, allowing the chain to slap around at start up and break off pieces of the guides. I replaced it fairly quickly and the engine runs perfect with very little valve train noise and zero startup rattle.

    Should be. That's the one for my M52.

    All right, I just ordered the parts for my M52! I can confirm it's even easier to replace since you don't need all those angled extensions for the wrench. There is plenty of room around the nut. I will report back since I occasionally get the tapping noise at startup.

    Why not replace the piston as well (item #12). There's bound to be a little slop after, say, 75000 miles.

    What say you, Doru?

    I thought so too. But I couldn't tell the difference between old and new slop, of course I left the new one in there.

    Replaced my spring yesterday. Boy was the old one compressed: about 5mm shorter.

    I already notice a reduced clatter in cold starts. Also replaced the plugs.

    I did mine about 3 weeks ago. Didn't notice any change whatsoever.

    I didn't even feel a placebo improvement.

    We can fix this.
    Now.
    Pretend you didn't do it.
    Pretend it never happened.
    Now.
    Bam.
    Your car will feel a change, quieter and smoother.
    Done.

    Just installed new spring today and there is definitely a noticeable difference . Crush gasket and spring was $6.91 from the local dealer including taxes.

    Did you guys fill it up with oil and then install it, or just install it w/o adding oil?
