Hello thanks for video I have check engine light m157 engine code p0018 and p0017 little long start when I go to start it has 98k miles

Good to see you back on track 👍👍

I just don't understand how to calculate the correct adjustment for the actuator rod; using a tape measure does not work. Code P029900 on a 2017 C43 AMG Turbo 1 (passenger side on left hand drive vehicles) I know you are supposed to use a vacuum gun, but I do not know what to do with it to adjust the rods. My next guess is to just tighten or loosen the nut until it moves at the same speed the other turbo does. Any ideas or thoughts?

As always, nice work and great content!

Beautiful Pistons and rods! That's one lucky guy in Tennessee getting this beast back from you!!

Hi Tasos what was the mistake the machine shop did. Curious to find out.

Don’t put it straight insinde ! Put in and move it a little bit around because you press air in the hole and you put to much oil insind !! Bad mistake !

Most valves are made from blanks that are forged into the near final product. The divot is a little offset because of this and does not affect its performance nor its durability. As a cylinder head tech, I see this a lot and I have never been concerned. Speaking of valves, before I disassemble a head, I use an engraver to mark my valves so the go back to their original positions. I used to punch numbers into them, but I ruined an entire set of exhaust valves on a "Hummer" H3 when I went to grind them and noticed they were all cracked almost completely around the valves head originating from the punch mark. Oops.

Hi tasos i have a question If the piston heting with the head (not the valve) what is the answer for that , thanx alot Note : head and bluck never been surfaced and the gaskit is standard size

Chuản rồi

I have washed M276 timing covers and removed heads multiple times on one engine before, it is the F-ing worst. Loctite SF7200 gasket remover is a must. It has a Mercedes part number.

Tasos you can’t fix stupid my friend….🤦🏻‍♂️

Hello Tasos 😁.and again another engine work of art is being created🔧🔧🙏.it will be a powerful engine beauty.best regards from Michael.

Hi Tasos This happened to me yesterday while driving my Giulietta QV 1.8Tbi direct injection. The car started to misfire on cylinder 3. I took all the spak plugs out to find out the no.3 spark plug tip had disintegrated and part of the electrode was melted and missing. Put a new spark plug in but unfortunately the engine still running on only 3 cylinders. 😢😢😢 The car is not tuned...all original and well serviced. The plugs are original and only 10.000 km old. At idle when running normal my boost gauge used to show a vacuum of -0.7 bar but now it's showing only -0.4 I guess im screwed😢 What could be the causes and what are the possible damages?

Tasos is top tier! If he ever came to Toronto I would want him to rebuild my m62 4.4 v8 (e39 540) 😅.

I cannot get over your EXTREME attention to the smallest of detail and your unbelievable knowledge with these engines. The way you point out imprints on the surfaces and are so knowledgable that they won't affect the integrity of the sealing surface is mind blowing. That guy from Tennessee, USA is going to have a permanant smile on his face that only surgery will be able to remove once he gets this absolute gem back from YOU. wow................😮😮😁 BTW, those Darton sleeves are so much GOODNESS!!!!!!😍😍😍😍😍

Can’t wait for next video! The best sounding v8 getting all freshened up!

Jaaaaaaag

Been working on these engines since the 4ltr Nikasil version and this is a nice build on an engine that responds well to careful handling.

Hello Tasos what chemicals or process do you use to clean the components that make them look brand new

I like your way of thinking about doing the job, going the extra mile.

Stevie Wonder must have been the engineer/machinist in charge of developing the valves!!! That's pathetic and thanks for showing us the variability/imperfections with the valves. 👍

My autism sufferers badly for seeing that off centric valve pocket. Does my C43 have the same thing? Do I need to take the heads off and look. It's really bugging me now. Having built fast engines and cylinder heads for racing motorcycles that kind of "flaw" is very irritating. Do the valves even weigh the same? I know it's meaningless but it's not perfect. And the engineer in me is screaming.

Another video I love. I love it when you glance at a part and see all kinds of imperfections from the engineering to the production of the part. It was so obvious when you spun the valve.

Not the cylinder wall 😢

What type of noise was it making as Reported by customer

Hi I need to contact u please give me app that I can text u at I got something about cla45 2019 I need to ask u about

Can you share how you wash this head w/ all of us. I never done one!

It sooo important to make sure surface is perfect. I made that mistake once not again. Triple check if i must.

Screw 😔. Know that feeling took my a6 to paint shop front bumper did not get damage. Was a rear hit. After collected my vehicle and change oil a mont after seeing like 7 screws in bumper under . Of coures i buy oem and place in correct location

Where most people would have become complacent a long time ago working on these engines and doing a half baked job, YOU on the other hand continue to amaze me with your continual attention to the most minute fragment of detail and addressing it to perfection...........literally speechless with every video with your knowledge and level of intricacy. wow

Good videos keep them coming

What is the recommended service of the PCV breather system in time or miles???

Hello tasos what hes the best oil with m157 with 180'000 km viscosity ? Thanks a lot for your amzaing work

The oil pick up should go, too important for it to fail!

THANK YOU Master Tasos for the inservice on the crankcase ventilation and catch can placement. After your wonderful inservice I've decided i don't need a catch can as I'll just keep my oil fresh like always and the change oil separator. I want to buy you a coffee if you have a Paypal or some other way to receive money. I am forever indebted to you! 🤜🤛👍

Bro what do you wash this parts with except petrol

You think its the rings moving causing them to bite on the cylinder wall? I heard it was over 70k to 90k mile engine injector wear/carboning so it bore wash that cylinder wall of oil or bent rod..... 2016 m278 and some 2015 are meant to have the steel bore and they claim this issue doesnt happen. Another words MB knew about this and change the bore material to try stop it. End of the day this bore material didnt work good for m157 and m278 for probably multiple reasons.

Where is the Mercedes from the state of Tennessee in the USA? I keep waiting for it to come up. LOL Good stuff sir!👍

Are all 722.9 4matics trans compatible? My w216 4matic transmission transfer case is broken.

is there any differenc if put used but in good shape block from m113 5.0 NA

And again another m157 that is among the most silent on Earth, noting that this is an excellent build would be an understatement

Great video and explanation. I have driven cars with both engines and always liked the 5.5 sound and feel and found the 4.0 to be abit muted and less " old school " V8 feel when they came out at the time but it is better for sure, not just about fuel consumption. Closed deck and cylinder wall material is huge for durability.

I will like to work with you

How do you prime lifters ?

Would you mind telling us how you do the washing of the parts? Nice video series!

“Classic” Tasos Moschatos speach 😁😅

🤦

This is funny. "OK what can I do to avoid cleaning those damn lifters..... ah, of course, put the oil in the supercharger" 🤣
