Work is from the top and front end. No need to get underneath the car, there is no access anyway.
I think you can get away from replacing the top camshaft gaskets as it's still new but do replace the front timing cover gaskets. They are only about £8 each side so worth considering
Phaser bolts are the large bolts that hold down the cam adjuster to the camshafts. They should be replaced as they stretch and are one time use along with the washers.

Happy to replace the gaskets as good practice anyway, will get a set of those for each side top and front covers and the phaser bolts and washers.
On a related note, is there any sort of online (or offline) parts catalog you can use to find part numbers for Mercedes models, ideally with diagrams?

Have a go here:
Mercedes FG 204.377 (61F) > Mercedes EPC Online > nemigaparts.com
Edit: I'm not sure I've chosen the coupe parts list there, but if you go back to the main menu on the site, you should be able to find it.

I love how members of this forum are so generous with their time and support for others.Just the handy tools, tork bit set to open up, lots of old rags, brake cleaning fluid (a few spray cans).
Small hand mirror and torch to set the timing to 40degree. I found removing the fans and radiator gives a lot more access, so usefull to keep some distilled water and antifreeze handy.
Also need the following parts.
4x new phaser bolts and washers.
Replace the front timing cover gasket (advisable)
Replace the top timing cover (advisable)
Will watch this thread and support you through the process
PS I wish I was handy with the spanner’s like you!
Happy to help. TBH, it's all self taught my good friend. When I was a kid, I used to watch my Dad mend his cars. No nitrile gloves, no power tools, no OBD code readers, just a Hayes manual and some spare distributor cap and feeler gauges were his popular tools
Just pulled out an invoice with part numbers, gives a breakdown of prices. The prices are about 2 years old so it should be roughly the same.
My camshaft covers are metal instead of the plastic ones, so your part number for the sparkplug seal is different and also the gasket to camshaft cover might be different too because you have the later plastic ones.
The phaser bolts, diamond washers, front timing cover gasket are the same

Legends, the lot of you - many thanks!
OK so it looks like:
MA156 016 21 21 - spark plug well gaskets (I'll need different ones)
MA156 016 24 21/64 - one cam cover gasket
MA156 016 25 21/64 - other cam cover gasket
MN910105 012018 - phaser bolts?
MA156 016 22 21 - front timing cover gaskets?
MA156 051 02 75 - phaser bolt washers?
Am wondering if there's any benefit in changing to the metal camshaft covers, are they less prone to cracking than the plastic ones?
In other news, the car announced this morning that it would very much like a B1 service within 30 days time and offered to call a Mercedes service center to have this arranged Won't be using our local main dealer, I fell out with them when my wife had a ML320 and they gave her the car back with one brake caliper effectively hanging by a thread. There's a specialist of sorts not far from here who did the warranty work on the C63 after I got it, will book it in there. I guess a B1 service is a B (major?) service with some extras?

Will you lock timing on both banks at the same time using 2 tools? Can be done using just 1 tool but very reassuringly helpful to lock both sides at the same time using 2 locking tools

Ah I see, oh well it is what it is I guess. Not sure I have a torque wrench that starts as low as 10NM either...
I was planning on working on one bank at a time rather than removing all four adjusters at the same time, surely no need for two locking kits?

No need at all, 1 locking tool will do but always keep an eye on the main pulley is not disturb and remains at 40degrees. Machine Mart and ebay great start for the torque wrench, will definitely need it because the camshaft adjuster screws will also require torque set to 25NM
I mean if the camshafts are properly locked on one bank then it shouldn't be possible to turn the engine at all, right? And if only one cam cover is off at a time then it should all be safe enough?
I have two Teng torque wrenches already, the smaller of which starts at 19Nm, happy to add another one to the collection I'll need a 27mm socket for the pulley too.

Totally safe, initially i did mine one bank at a time too, working slowly and methodically. The phaser bolts will also require torque to 90NM and then a final 90degree turn
Camshaft adjuster screws I read were 14.7Nm? And I thought the phaser bolts were only 27Nm?
Edit - this is where I saw the 14.7Nm for the adjusters - M156 M159 Camshaft Adjusters Wear Problem - JMSpeedshop !

The way I did mine, watching Tasos video is placing a mark and retighening to the same spot, it took 25NM with a blob of thread lock at the end. Wrench do have some +- inaccuracies but I wouldnt feel confident anything less than 20NM, could run risk of screws becoming loose
Some heads up tip too from me and my experience The kit comes with pins, don't use them. Use the original ones, as they are mated to the aviators and will be in good condition as the pins are hard wearing. Also, the videos show to stretch the springs, don't do that. Keep the spring as they are otherwise you'll risk wearing out the tiny plastic spring seat.

A nice accurate inch pound torque wrench is a great asset in any tool box. I've used mine loads since I bought it about 6 years back. I bought it for the injector clamp bolts on the 2.7 5 pot derv originally as they are easily over tightened or even snapped but now I use it on all the little bolts I would previously have done by "feel". I think mine goes down to 5 nm.
Thanks again gents! I'm *almost* looking forward to doing the job now - in the past I'd have been chomping at the bit but as I get older I find I have less time and patience for car DIY. We'll see if this rekindles that or not!
I wouldn't be without my torque wrenches now, used them hundreds of times for jobs on loads of cars, ours and friends and family. I had a 4.2 XKR and then a 5.0 XKR for a total of about 11 years and did almost all the work on those myself so those wrenches and all the other tools I've collected along the way will have paid for themselves several times over by now. The Teng wrenches are very sturdy, I did cheap out one time and bought a Silverline one but it disintegrated on me after about a year so it was replaced with another Teng.

Cheers It'll be a little while before I get to doing this, I'm working my last few weeks at my current job just now, on holiday last two weeks in October and the car is booked in for detailing and ceramic coating w/c 6th November so I won't get much of a chance before then. Need to get it serviced soon too, will try and get that squared away before going on hols.
