Om651 Engine Rework
Car W212 om651 came to my shop due to the knocking sound and found due to the engine slapping 2 pistons are scratched in to the cylinder bore
I am newbie for engine work ,really no idea how to start this project .If I would approach engine bore shop and expecting lost of question from them that should prepare to my self .
Th real Challenges are Used engine block not available in my area , Engine bore team not much professionals or not much advance machines are available .
The work I assume that the engine for cylinders they will put new sleeves or any alternative solutions, if what would be the sleeve measurement how to install the sleeves . as per the workshop manual the om 651 bore size would be 83 mm (3.27 in) so the sleeves inner measurement should be 83 mm then what will be outer :, engine team would remove the original existing sleeves from engine or just bore and reduce the inner size if how much size .
I am really sorry if its are foolish question ...
Could you please please explain to me ....
Thanks in advance.

Something like this one, 2020 version is good enough : https://www.ebay.com/itm/383842456251
Or try find seller with online download, easier for you, no need import of the UBS mini stick.
Its like 10GB at the most if I recall, mine is a 2018 bought in DVD
, also from Ebay.Good luck

Perhaps you google OM651 used on commercial vehicle, maybe you will find someone sleeving the block...maybe.




A Second hand engine is the only solution.
