    FOR THE LOVE OF GOD! please everyone reading this comment remember to replace the O ring that sits on the EGR cooler under the manifold. I did this job with my ol' man and after a long time putting it all back together the engine coolant was pissing out the bottom so we had to start all over again from the beginning 😭😭😭 learn from our mistake and purchase that seal!!!

      @@joesaric1 ive owned my chrysler 300c v6 CRD for few years now and i still love it. Ive replaced all the common faults including the broken gear shift plastic hook and these bastard seals, i would do it all again to keep it running.

    Great video. Thumps up from my side. Thank you for sharing.
    But please also add important information's for all watchers.
    1. be careful at the moment where you are removing the turbo-holder.
    At time 3:33. There is a hole which goes directly to the motor-center. It is the oil channel of the turbo. If there some dirty stuff falls in, then you are risking a motor damage. Be sensible and clean it carefully immediately. And close with paper towels the hole before you proceed.
    2. after you are done, please make an oil change before starting the motor. Water and dirty stuff is mixing through the oil holes under the oil-cooler. I got a lot information's where after this oil-cleaner change the motor got damaged through this dirt-water stuff.
    If you are done with the change of the oil-cooler and oil+oilfilter, then you should release a plug of motor electric and give some start tries to turn the motor/pump and so on. After several turns, plug the removed cable back. Start the motor and of course delete the occurred error message in obd.
    These are just my hints for the community in yt ;)
    Wish to all much success...

    if i could add one comment other than nice clear vid , one tip id add is when reinstalling intakes loosely install the bolts into the egr to exhaust flange shown at 2;48 in this video before you tighten down the bolts for the right hand intake manifold to save many stressful attempts to line up the bolt holes after the fact.

    Hi merc man ive changed more than 30 sets of oil cooler seals mainly on w164's. I leave the thermostat housing on taking the long bolt out and leave the swirl pot motor attached to one half of the manifold. Disconnecting at one point towards the turbo, makes it slightly easier. Best time 5.5 hours drive in then road test all parts ready to go including brake cleaning oil down. Some do take longer, bolts on turbo and egr need to be changed other wise they have a greater chance of snapping for the next guy. Like your clip simple piece by piece break up. 😉

    Great video! I'm wondering how long does the fix last and have you seen any OM642 leaking again after replacing the seals? I'm viewing an 2012 ML350 this weekend and it has had the same issue and Mercedes fixed it with Mercedes parts in 2018. Mercedes replaced the oil cooler seal (MA642 188 05 80), oil cooler sing (MA642 180 01 65), and bunch of other gaskets. And looks like the Mercedes parts have defects and would not last long, I'm worried that the oil leak will happen again on the car I'm viewing in a few years. Thanks!

      As u can see there is tones of work to do. For mechanics, they don't wanna take any risks of a bad cooler and also they need to make money from parts. TBH,I believe the main reason is they don't wanna take risk doing all of these shit again and if it's mechanic's own car they would change the cooler as well. Time is money.

      If you drain the coolant from the engine side ( there is a plastic block in front of the engine where the belt is left side if you drain it from that pipe) then most of the coolant from the inlet manifolds and the turbo cooler should be empty so there shouldn’t be any contamination if your careful with the work, id also loosen the oil filter so most of the oil will end up in the sump, and if your careful there shouldn’t be any contamination

    • @ssss-df5qz
      @ssss-df5qz 2 роки тому

      Just do the obvious.
      Remove the rubber grommet on the bell housing of the gearbox to see inside there if it's a crank seal.
      Check the silicone seals on the inlet to the turbo and from the PCV valve to the inlet. They leak oil onto the swirl flap motor and short it out, blowing fuses and throwing codes. This oil will eventually drip between the engine in the same place as the oil cooler but wont be enough to overflow into the weep hole on the side of the block.
      General rule of thumb with these - it's the oil cooler seal.

    Hi MercMan, I thought Mercedes knew about this problem way before 2012 and have had been using the purple seals ever since. Do you think the 2014, w166 series OM642 would have already been modified?

    • @mercmantips
      @mercmantips  4 роки тому +4

      Hi, when you order the seals from mercedes they only supply the purple ones, you cant get the orange ones no more, i have done a 2014 c class W204 OM642 and they had the orange seals, so i think your W166 will have orange too..

      They are the gaskets for the turbo cooler block, so there is a block under the turbo and theres 2 gaskets on that

    Question: is there anything someone can do to prevent (or reduce the chance) needing to replace those seals? Perhaps a different oil?
    I've got a 2007 R class with the OM642 engine. it has 215,000km, it gets an oil change service every 5,000km, using 5w-40. It hasn't had a problem (knock on wood).

      Hi Ali, from my knowledge and experience these seals perish due to heat and where they are located, so i don’t think there is anything you can do to prevent it, the new seals however are modified to last much longer so the only cure is to change the seals..

      That's a shame. I've read about a ton of common issues with the OM642, including the oil drip from the turbo inlet, but I've solved that by installing a catch can. Makes me wonder how effective R&D was for this engine 😂. I guess I'll have to keep hoping nothing happens anytime soon.

    Did you know that the core problem is that the orange silicone rubber gaskets are incompatible with the diesel oil? I first noticed this when replacing the turbo inlet seal after only a year and I could rip it with my fingers. Mercedes replaced it twice at 100 000 and 200 000 km. I also had oils leaks on the vacuum pump that has the same rubber gaskets

    • @Bobby2106
      @Bobby2106 3 роки тому

      This is what I've found: "The pre-2010 OM642 engines were notorious for leaking oil from the oil cooler seals. The original seals (orange colour) weren’t able to withstand the heat and developed leaks. Updated seals (purple colour) were introduced in 2010. There was a recall for this issue, so hopefully, most vehicles would have had the seals replaced by now. Before buying one, check if the seals have indeed been replaced and inspect the car for oil leaks."
