1 second engine rattle on cold start up (M271)

Yes I see. I think based on the small damage to the top of the timing cover, a new chain, tensioner and guide will be in order. I can then drive without a troubled mind 🥲

Just looking at INA kits, who are said to be OE manufactures for chains. £115 on eBay. I’ll get a quote from MB tomorrow but am expecting that price to triple at least.
 
I had this job to do about 6 months ago.
The engine was at about 90,000 miles.
Your sprockets look good from your photos.
I would certainly replace the chain and the tensioner and the guide.
Timing is very critical, but the timing marks are easy to see.

On start-up, there is the slightest engine rattle.
Not uncommon until the oil pressure builds up.
Other than that the engine runs very sweet.

About the same time I replaced the thermostat and spark plugs.
The engine was running to cool due to a jammed stat.
The plugs fitted were the wrong type.
All is now OK.

Glad to hear you carried this out successfully. 👍🏼

I am ordering the parts now and will soon get this done when I can find a chain crimper to borrow, I’m just in the process of asking around.

My timing marks are a very tiny bit out, likely due to the chain wearing, so I just wondered about the process to reset them, which I am struggling to find information on.

My thinking was if I ensure I am at TDC on cylinder 1 once the new chain is fed in, I can then set the camshafts to align with the timing marks, then lock the cams and proceed to crimping the chain.
 
@RAJ55 Just wondering if you still have the crimping tool and if I could rent it? I am not too far away from you.

I think otherwise I am looking at using the Sealey motorcyle chain crimper recommended by Jay in another post.
 
Have got a Febi timing chain kit, all the parts are branded IWIS, OE chain manufacturer as I understand it.

The guy at the parts store said all Febi chains are INA or IWIS.

Febi Bilstein make some bits, and repack others, nothing wrong with that as long as you know who actually made the part.

INA is indeed OEM for bearings and other things, personally I have never heard of IWIS (which does not mean they're not good...).
 
First time I have heard of IWIS as well, but from what I have looked into they seem reputable.

There is a handy list here I found some time ago, can’t vouch for its accuracy but it was a good starting point for me:

Thanks, I’ll send one as soon as I figure out how to

Roughly what did that job cost buddy ? Says a fellow M271 survivor.
 
Unfortunately I don’t have this option. Not sure why, I think I have posted enough. I have two options, to follow or ignore.

Mercedes Benz of Newcastle have a set of genuine spark plugs for a reasonable price mate @W1ghty

The genuine MB spark plug for the M271 143bhp engine is Bosch FR6MPP332 - A 004 159 45 03.

NGK recommend ILFR6A (Iridium tip), which they refer to as 'Upgrade'.

Interestingly, you can get MB-branded NGK ILFR6A from MB - A 004 159 13 03:

Though MB never actually specified them for the M271.....

The job would have cost approx £1400.
I got it for slightly less, as I had already bought the camshaft solenoids and the wiring pigtails.
These are easy to change.
I also recently changed the spark plugs.
Got them from MBofNewcastle.
