A friend with lot of experience working on MB's and other cars, and I were removing the rockers on different sides of a 380sl engine when I noticed that he wasn't keeping track of where each rocker came from. However, when I admonished him for it and told him the MB manual says they should be replaced in their original position, he confidently replied that it doesn't make any difference because -- if i recall correctly -- "the cam lobes glide on a layer of oil that evens out any differences each rocker surface may have." So I ended up mixing the rockers I took off in with his.
I was recently told by a Master MB Tech, however, that rockers should definitely be reinstalled on the same valve, because not doing so can wreck the corresponding cam lobe. So now i'm wondering what the odds of that are, and whether I have to get new rockers and/or cams, considerng they're all in very good shape.
Any advice would therefore be greatly appreciated
