I read almost all comments and nobody wrote something about the piston. So here we go, what if the pockets on the piston it was in the right place, what would have happened?
Tasos, PLEASE HELP: I had the same issue and my mechanic fixed it exact same way. It runs well, but soon after the fix I started hearing a minor chain noise at cold start up occasionally. I don’t think it is the adjusters. What could it be? What should I ask him to recheck for?
Same result I imagine Tasos- the pistons relief cuts are for clearance in normal operating conditions and not when some knucklehead allows the cams to get out of timing. I imagine that the level of piston to valve interference throughout the combustion cycle is much more than the few millimetres that the valve reliefs give. Any risk that one could bend a Conrod in these circumstances without damaging the crown of the piston?
@@markraumer2336 since there's is no dent on the piston means that the valve barely touch, if the relief cuts was in the correct place we will not talk about that now.
I'm in the market for one of these in Australia so it's encouraging to see that a 200k engine looks so good in the bores. As long as the owners carry out regular servicing there is no reason that these motors can last a long time. It looks like the only Achilles heel is the cam adjusters and wear on the cam lobes and buckets. Adding something like a LiquiMoly anti friction oil sounds like a good option. Great video man. Thank you.
Dude put the hood up into the service position! One of the best quirks Mercedes Benz has! It pains me to see you straining your back! Great work though! Keep it up!
Thank you for posting this! I was always curious what would happen if the camshaft adjuster completely let go and caused the timing to be off what the damage would be. I have also been curious about getting the head machined when replacing headbolts and your explanation was very thorough! Great content as always!!
My question on the head maching as well. As far as bolts. Say if oil and coolant mixed due to broken head bolts and head needed to come off one simply needs to check with micrometer to determine head trueness. Could not find that anywhere for m156
that cylinder bore surface is ultra hard, amazingly minimal wear after 200K kilometers! MBZ went backwards with the M157 and that softer coating in the bores.
As much as I would love the power of a C63 over the power of my C55, I am reminded why I won't be getting into one of these when I see how difficult and mainly cramped it is to work on.... Also, how nice is it that one guy who you know, knows what he is doing is working on your car the whole time!
I agree , I have CLK55 ,,much less complex than M156,,sure not as much power ,,but so reliable ...a good balance between power ,reliability and fuel economy.
Venom63 I know it’s not THAT bad but still, 300-400k miles are practically dime a dozen when it comes to the m113. Time will tell if that’s the case for the m156, just seems like they are hit or miss in some regards from stories. I’d still pick one up if I found a steal of a deal 😂
I'll check out your swap that is cool! Anyways, I agree that the M156 and M157 is hit or miss quality wise. So much so even that I am shocked! I would forgive AMG and Mercedes-Benz if it were due to just the nature of having a more powerful engine but there are so many failures popping up due to poor quality control or casting errors in ways that are almost unforgivable. As if the engine builder slacked off or the QC people just went on break.@@ANDERZENAMG
Awesome video. I recently rebuilt a k series. Skip timing bent 8 valves in the head & did main bearings & rod bearings. Today was my first drive. Love the feeling of accomplishment .
Man great videos. I just watched all the ones when you did the rebuild on the m113k engine. Full of knowledge. Respect from Chicago. I'm about to start dropping the engine on my cls55. Thank you
The valve clearance on the piston main design is to make clearance for valve closing timing 10degree BTDC on all engine... Even on race application, this is the standard used... The valve relief wont take accounts of "out of timing scenario" on interference engine... And the valve indent on the piston shows exactly that out of timing condition...which is normal the indent so far out of place than the machined valve relief on pistons... Just in case u wondering why its doing that...
You are smart! That is incresibled that you are able to remove those parts and put them.back together. My daily drive is a Porsche Cayenne Turbo it is not easy to work on it.You remind me of Sam,y favorite Indian mechanic, he drives a Lotus.
"What I love about these Mercedes cars is, the first time you fix them, everything just works on them." Er, what about that Merc R class you had? Worst car you ever owned, you said
Problem is, the fix can be a few times more costly than the entire car at times, our w639 Viano needs to be rewired completely because of a factory fault that allows wires to wear and short out, causing every single system in the car to stop working correctly
@@xfmotorsports in russia they swap the toyota/lexus 3uzfe engine in those mercedes Rclass and in many other mercedes like the sprinter. They even swap the 3uzfe in range rovers, porsche cayenne, gwagen....
hi, how long do you think it would take to replace head bolts with the new type(assuming none break off while removing the old)? Thanks for the video!!
The check engine light has to be the teach in procedure for the adjusters being needed, done via Xentry. I was just curios exactly how much smoke (antifreeze burning) did the car make, once you let it run? You must have spent time with compressed air removing antifreeze from the head bolt threads, especially since you didn't drop the antifreeze from the block. The red stuff on the bolts was assembly oil, or ATF? which assembly oil did you use?
I have the same c63 that is continuing to misfire. Catalytic converter was clogged so dealership replaced that along with intake manifold. Removed the secondary cat and installed long tube headers at a shop and also applied a tune. The shop test drove it and it still had a misfire. They took off the tune to test it that way and still misfired. What are your suggestions on what our next step should be.
Would the car start if the values were bent? As I'm in a situation where the cam adjusters got replaced, and the timing is right but it misfires on cylinder 1&2
And the other thing im not familiar with mechanic things but i like DIY most of my things getting information on net i hv w203 C320 v6 n C240 engines i swapped the engine n put C320 into C240 car it was starting gud but the oil pump wasnt working so oil wasnt circulating n the engine makes a noise like smthing hv droppedin inside which i think myb it droppes the valve or bend conrod so i wanted to ask if i can take the head for C240 n replace the C320 head with C240
I was going to comment on the cylinder glazing until you said its got 200,000km plus the wall coating. That would explain it! I'm looking at an S550 with over 200,000 in it. Fingers crossed
why does a Mercedes Benz engine have so much parts and component unlike other cars, weather they are performance or not. can you explain pls. they are my favorite brand
Your a boss🙌 wish you would work on my 2009 c63 amg, it had a pop in the engine and started smoking out of one exhaust pipe and threw a check engine light now... 😵
Haha never thought I'd hear Mercedes and reliable in the same sentence. Although credit is due having a m113 engine that was still running although barely with 240k miles on it. But hey at least I had a reason to ls swap it. Looks like you will be needing a bigger shop soon with all the things you have coming up. Keep up the good work. If I am ever in the area with my GM wagon I'll stop by for an alignment
Only reason this motor bent the intake valve cause of bad repair by shit mechanic he said. All engine rebuilds on this car are top end as well easy to fix
I recently replaced the conrod bearings in my Caterham (2.0L Duratec) but I reused the bolts, now I'm really scared that the bottom end will go... 200 miles on it with no issuess so far, should I order some new rod bolts for pease of mind.
Yikes! No! Rather make a toolsteel insert so that hole does no wear out again. Make a toolsteel bushing on a lathe, machine the hole bigger, then weld the bushing in.
I think you should use covers for the car while working. I am confident that you are careful not to ruin the painjob, but some customers would definitely appreciate if you are extra carefull with the car. A good image is always important.
I have done a lot of work on my cars over the last 50+ years but never touched an engine. Way complicated. I guess you have to be smarter than me to do it and do it right. I noticed you use LiquiMoli oil. I use it on my e320 which I find very reliable by the way. How many miles should you run that stuff?
Hi .thanks you for your videos, i larned a lot from you!!! I have a question.... Why do i have to change the head bolts ? Can i use the same ones? Thanks.
Do you know if this c63 is a P31 performance package one or is it just the standard one? Would love to know cause of how the piston held up and the cylinder lining
It’s just the standard one, you can tell because the intake manifold is a light grey colour, the engines with dark grey intake manifold has the performance package, also the lite grey rocker covers means its 2010 or below, the 2011 and above has black rocker covers
Absolutly love the content! I'm only at a 8hours drive from your shop, I am studying to become a mechanical engeneer and I would absolutly love to give you a pair of hands for a day or two completly free just for sake of learning and seeing how you operate your shop! Please hit me up if you think that would be possible. It'd be a dream come true for me.
