    M62 TU timing chains and Vanos rebuild

    Hi All.

    Iím in the middle of replacing the timing chains, guides and rebuilding the Vanos. The upper u shaped guide decided to part with its plastic.... M62 TU timing chains and Vanos rebuild

    Just got the lower cover off and thereís a lot of black gunk in there. Is this normal for a 265000 km engine? Or was it poorly serviced before I bought it I wonder?

    Maybe it's normal with an engine with that many miles on it. I've worked out that we have to use synthetic oil in our M62's. They run so hot that they would fry normal oil. I've been monitoring my engine temps and normal temps are around 115 deg C on the highway and get up to 135 around town.

    I'll be looking with interest in what you are doing as I think I need to do the same with my engine.

    It has a little rattle for half a second when I start it up.

    Ah yep that could make sense... Iíve only been using full synthetic but thatís no guarantee the last person didnít! Once Iíve gotten it done I can post a list of part numbers here for you if you like fisherX.

    Itís a pretty straight forward job - but thereís some major things that rave seems to skip over - like how difficult it is to get the injector electronics off - you need a pick tool(s) to remove all the metal cir clips on the connectors before removing the electronics boxes. and the crank bolt.... so tight - a one metre length of pipe over the breaker bar and you could still see it deflect.



    Swapping out the Vanos seals. The ones on the left are the new ones. This was actually pretty easy if you follow the instructions on the Beisan website:

    long piece of steel pipe to extent your breaker bar
    rave manual and Beisan systems guide

    ill let you know how it all goes once done. The new chains are all on now. Just have to put it all back together...

    ps FisherX: my engine was also doing the half second rattle at startup - and then sounding like a diesel if you opened the hood. I would recommend doing it asap. All of the plastic guide parts were so brittle.

    Update.

    It runs!!

    Massive job. I went for a low speed drive up my road and back (<20km/h) and it definitely sounds healthier than before. Two issues to sort out tomorrow after work:

    The PAS pump seems to be making some noises when I turn - belt too tight? Or loose? Rave didnít say what deflection to put in so I just did it by feel.

    Thereís a flashing yellow engine occasionally. Could have been in groups of three - but I think Iíll just check everything is plugged in correctly - tomorrow.... fingers crossed M62 TU timing chains and Vanos rebuild

    The Febi 47500 was $282 off eBay.
    the upper set and tensioners were $75 off eBay (got a bargain though)

    does anyone have the part number for the power steering pipe that connects the steering rack to the lower connection on the oil cooler. It appears the connector on that has gone on mine - I tried reseating it but it exploded putting fluid everywhere while I was bleeding it. When will it end!?!?
    the hose in question is the brown one circled in red.
