M156 Camshaft bearing caps indification markings
Hallo
Got 63k mile on my 2008 E63 before I got a low coolant warning.
Being member and reader of the awesome forum I'm aware of the flaws some of the M156 engines have.
Got home and topped up with coolant. Almost a liter was needed and with no external leaks I knew almost immediately what the issue could be.
Out of warranty and knowing how Mercedes deal with this I decided to pull of the cylinder head covers.
I quick look revealed at least one cylinder bolt head had snapped. IO had become victim for the famous and ridicules cylinder bolt issue.
My "baby" was dead
I took on the repair project myself and that was brings me to the topic!
Until now I thought I had everything under control until I realized I got some of the camshaft bearing caps mixed up
A check in Mercedes repair manual indicates the importance of mounting them according to the markings however no further instructions
I have exploited internet and this forum and found no references to what the markings refer to and in what position each cap are supposed to be mounted?
Is there any of you guys that have that knowledge and would be helpful in sharing that.
It would be very appreciated it
Thanks by the way for a great forum....

Come on guys
With all the engine cases discussed here in the forum there must be some that have noticed what number order the bearing caps should be mounted in!
Would really appreciate some advise
