Spray welding alloys are available that are harder than the original camshaft journals, and will give a better bearing surface than the original.
You have probably noted that over time MB eliminated some of the journals; eight on the exhaust side were reduced to five, and seven on the intake side were reduced to five.

Of course a new or good used cam box whit cams and probably the chepest and best soution BUT! The cams are regrund dbilas cams, all the lobes are perfect and I dont want to throw away two 500 euro cams :/ And lets say I get a good cam housing. The wear surface on the cam journals are still bad. And to be honest, I do think it is a bit of fun to see if i can fix this problem using the old cams and housing. Yes, I noticed. The engine is from a very late W126 280SE and only have four jornals on each cam, well it has five on the exhaust cam but only use four. The fifth dont have any bearing surface to run agianst.
