Currently as we speak Im rebuilding a OM642 out of a Sprinter. Mine was using a quart of oil every 100 miles. Found oil rings collapsed and expanders broken. Extreme carbon in intake ports, almost closed up. Id be very interested in other videos of this one your building now. Just curious on path you guys took on rebuild. I had mine honed and checked, reusing pistons and installing new rings and bearings amongst other parts. Im also interested in the cost for customer. I cant image what this would cost me using OEM parts and paying labor cost. Im assuming 40hrs labor at $125 per hour. Ive built several engines at Honda and Toyota dealers but this is a first on Mercedes Turbo Diesel. It's been a different animal for sure.
Its a real shame Mercedes didn't made the PCV a serviceable item, at least every 50k km. It seems that when they fail, they put so much gunk in the intake that it gets completely f-ed, and the combustion chamber eats all that nastiness/oil, in return creating more soot than normal by burning it which is washed away by the piston rings and gets them stuck. A $50 item changed in about 2 minutes can end up costing a full rebuild...
@@MercedesBenzTechs Thanks for your quick reply! I recently bought a Vito van with 80k km . I added 2 bottle of CeraTec (2013Vito 122 CDI V6 engine)2 weeks ago I really hope it doesnt do any harm for engine … Do u think Mobil1 5w30 ESP is a good engine oil for this Vito? Thanks heaps mate
Does this engines diesel pump need timing if removed to tighten the bolts on the backing plate ?? I have come across comments saying it needs timing and others saying that doesn't. There isnt many videos covering the fuel pumps of this engine an none installing them
You don’t happen to have a video of you walking through doing the timing on this engine do you? As far as marks etc when doing it from scratch. Thank you
@@MercedesBenzTechs yeah, I saw the marks on the cams but I hear mixed things on the balance shaft. Some say the notch on the weight goes to 12 o clock and I see others that say line it up with the line on the casting. Do you recall that off of the top of your head?

I follow and subscribe to your channel as its very informative,I have a question will a mercedes 320 engine fit in a 350 engine bay,is it the same engine?,both om642 920
I agree but it’s not only the engine it’s the whole emission control process, the add-blue, Nox sensors, Turbo, seals, direct injection… I stopped taking this engines in my shop, Mercedes should buy back all this cars and pay back the billions of dollars people spend on this cars.
@@MercedesBenzTechs they did have to buy back my E320 Bluetec. I’ve had 20 Mercedes over the years but it was the worst and almost cause me to switch brands. Bought a gasoline E350 and is a great car and great engine.
I have 886K miles on 2013 Sprinter and 450K on 2019 Sprinter with this engine and never rebuild. How is this worst engine??? Maintain it with proper stuff it will last
@@dariodjakovic1600 I maintained it by the book and the year it went out of warranty it cost $9000 to keep it on the road. The reason that the E class with 642 BlueTec engines are so rare in the USA is that most have been junked because the repairs are more expensive than the value of the car
@@vintagehaynesflute the one used in Sprinters takes almost 14 quarts of oil and one used in w211 uses like 8qt of oil on oil change. Lubrication is the key to longevity. When it comes to W211 E320 CDI the 2005-2006 with inline 6 OM648 engine is some of the best diesels ever made.
Hi I was wondering what is the cost to rebuild an engine for an 09 GL320 like in the video?
Thanks in advance
Hi.

How much does it cost to rebuild OM642 engine?
Hello i want to ask you where is located oil pressure relief valvle on om642 ?
Would you recommend any oil additives like liqui moly CeraTec for this kind of engine
Any recommendations most appreciated
I haven’t seen a significant results from additives, just change oil when it’s due with high quality product

Thanks for your quick reply! I recently bought a Vito van with 80k km .
I added 2 bottle of CeraTec (2013Vito 122 CDI V6 engine)2 weeks ago I really hope it doesnt do any harm for engine …
Do u think Mobil1 5w30 ESP is a good engine oil for this Vito?
Thanks heaps mate
Thanks for explaining that. Did that engine come out from top of the car together with transmission true hood or under the car?
Engine from top after dropping the trans from the bottom..
Thank you for the great video. Do you think you could have removed the engine without dropping the transmission?
Does this engines diesel pump need timing if removed to tighten the bolts on the backing plate ?? I have come across comments saying it needs timing and others saying that doesn't. There isnt many videos covering the fuel pumps of this engine an none installing them
It doesn’t, it has an engine computer that control the injectors.
@@MercedesBenzTechs thank you very much for replying. Much appreciated
You don’t happen to have a video of you walking through doing the timing on this engine do you? As far as marks etc when doing it from scratch.
Thank you
I don’t remember if I do or don’t but this engine timing is really easy, there are marks on the cams
@@MercedesBenzTechs yeah, I saw the marks on the cams but I hear mixed things on the balance shaft. Some say the notch on the weight goes to 12 o clock and I see others that say line it up with the line on the casting. Do you recall that off of the top of your head?
@@Frank-i-e not from the top of my head, I can check WIS tomorrow
@@MercedesBenzTechs that would be so awesome if you could. Thank you!
@@Frank-i-e do you have a cell phone I can send you the diagram
Hi Guys
Left a question concerning had a turbocharger changed but now the car has a lot of smoke from exhaust and no power on throttle
What year and model is your car and what type of engine you have
@@MercedesBenzTechs w211 mercedes e class 52 plate. Had her valve and turbocharger changed but smoking from exhaust and loss power on acceleration. Thank you TC
was hoping to see the rebuild....
WHERES THE NEW VIDEO OF THE 642
I’ll check if I posted it
Happy birthday to you brother
Thank you my friend
@@MercedesBenzTechs please help me check your mail

Yes, change the wire harness because there are few difference but yes it will.
@@MercedesBenzTechs thank you,i will have a go,hopefully straight swap,will my ecu on car be ok with the 320 engine?
