Love the M156 work Sam. Mine had over 400k miles but totalled that C63 last month( :( ) But i did replace it with an E63s WAGON so im pretty stoked about that!!!! I have torn my M156 down to the absolute core more than once and LOVED working on that engine!!! So over-engineered but so logical....When i did my bedplate reseal the only thing different i did was cut the heads off of my original M9 center bolts(1,2,5,6,9 and 10 in your diagram) so that i could thread them in and use them as guides for the bedplate to fall in place as opposed to doing the hover/hope/pray method....Great content my Friend and keep up the good work!!!!! and fwiw(and as much as i LOVE the M156) the M177 with downpipes and a tune is BRUTAL!!!!!
Using the old bolts as guides is a great tip for anyone else tackling this job, wish I thought of that at the time! Awesome to hear about your 400k mile 204, sorry to hear about its demise. 213 E63 wagon and AMG GTS/C/R are on my list of future cars some day, drove a buddy’s GT63S with downpipes + tune and it was awesome
Did the same job. If I were you I would have sealed the bed plate with an anaerobic sealant such as loctite 515 or 518. It’s the better way to seal two machines pieces. Not Mercedes silicone does not last long and will eventually leak again.
I have only heard of horror stories of using other sealants which I why I didn't try to get adventurous. That's a good suggestion though, I'll try that out on some M113 PCV breather covers or when I have to do this again on my C63 haha
