Is there a way to check timing chain with tearing engine apart?

mickey - will some oil leak out of the engine when you remove the tensioner?
Man, I should've done it when I was replacing my alternator
I would hate to R&I it again... Maybe will just go to an indy.

16. Attach two tube sockets to the cams and secure tools with a tie down/ cable tie before removing the link. (I used a tool I made to press the link out)
19. Slowly turn the engine at the crank and keep the cams in sync. As you get to the point there you need to move the sockets back, make sure the cams are not in the place where anyone will jump. Be careful not to be in a hurry and keep the chains (both) on the sprockets and lined up.

I agree. As many DIYs as there are on this specific subject (c230 m271 timing chain install - draw through method) it seems none cover every detail that the typical DIY driveway mechanic would need. I'm sure most can figure out how to get passed the gaps, but aren't DIYs there so you wouldn't have to?
Few things I'm still trying to figure out...
Tensioner plug/seal part number - Ahaa!!! FOUND IT! I think... 000 997 62 20
Will verify at the Dealer tomorrow
The easily breakable "weak" cam bolt that can occur while removing the cam cover?
https://mbworld.org/forums/5393235-post224.html
Timing chain retainer tool / home made metal brackets
Feeding the chain process. I see how you would turn the crank pulley to draw the chain down in on the intake sprocket, but at the same time you have to pull the chain coming up and over on the exhaust sprocket. Is there much resistance to turning the exhaust cam while the chain is coming out?
Looks like AutoZone might have a good method.
One person does this while another turns the crank pulley... slow and careful

000 997 62 20 is the base OEM Mercedes part number. The -INT and -MBZ is just what Pelican adds on to distinguish them as their own part numbers. This is typically when they have alternate brands of the same parts.
*edit...
Just stumbled on this as well

Speaking to VVF he mentioned that his indy checked timing angles through star and were able to say that the timing chain was not stretched based on that data. I guess where I am trying to get at is, can this data be directly related to timing chain stretch?
I ask because we can conclude MAF data based on how much adaptation the car is doing. Couldn't we conclude this data based on how much angle adjustment it is doing on idle?

There is no DIY on replacing the timing chain and tensioner that has enough detail, there's a WIS, which in my opinion sucks unless you've been working on cars your whole life. The parts to correctly install the chain are ridiculously expensive, and there's no youtube video that goes through how to get the timing right without seriously fuking up your engine. So here's what I'm doing. Since I'm close to 100K miles, rather than spend $ for a mechanic to tell me whether I do or don't need a new chain, I'm getting one put in. But, I bought the parts first and then shopped around the labor. If you start by saying you bought the parts and are over your head, they'll tell you some bull**** about not being able to warranty it for life, and then agree. Ask them if they've done this before. Tell them, before they quote you, that lifting the engine up is not necessary and the quote will be b/w $550 and $600 for a reputable indy. On a 4 cylinder engine, you can get the victor reinz valve cover gasket set, then get tensioner OEM and cap (listed in a post above) and the timing chain, possibly some timing cover gaskets. So the total is $750 and it sucks, but what are you gonna do?

no, incorrect. This is ONLY for the 6 cylinder engine that victor reinz gaskets cause leaks. There is a LOT of misinformation, especially for something everyone on this forum preaches as Supremely important- namely replacing the timing chain. I'm giving you the least headache way of getting the job done. Simple and to the point.

Check this ***** out. I just picked up my car from an indy cuz they couldn't do it. Didn't have the tool so they reimbursed me for the rental car. SO ANNOYING! For a job that's supposed to save the engine, there sure are no mechanics who are aware of this service. Literally, no mechanic in South Florida has done this on an M271. FRUSTRATING.

It's not a difficult job, just take your time. I did mine mostly solo, had some help feeding the new chain in. My old chain was stretched about 2mm at 125k miles, so the replacement was unnecessary. Car sounds exactly the same as before, I have a vid on this thread...

thanks much for the insight. I believe it's an easy job too. As long as time is taken to pay attention to the important details in regards to timing and making sure your marks align. If the chain is fed with the old one, and the engine had not lost time then it should be a piece of cake.
What chain did you go with? MB part or Iwis?
