BRABUS M104 3.6-24 pistons rings failure
Hi there.
I just riped apart my engine to get to the bottom line of my oil cunsuming problem. 3-4 L / 1000 Km. I found the pistons (compresion rings) where broke. Why is it that this could have happend? The cylinder is looking great wthout any marks, edge or damage. Now of cause the pistons rings havenīt got any use when broke, becuase they donīt have the presure against the cylinder walls any longer. But could this just happens because the engine is worn out, (the cylnder walls is still looking realy great without any top edge and the bore strukture is still there, so no worn out cylinder walls. and engine have only 180K as told. on the clock. BRABUS tells that you can only go for the Castrol Edge/RS 10W/60 engine oil. But the former owner didenīt pay this any attention and just put in what ever oil he could found at a disount price. ![]() The rings look very dark and "hot" but not worned out, but I donīt know how they should look. but I know each ring is suposed to be in 1 piece and not several ![]() So would it just be a simpel job to get new rings on the pistons and then use the right oil or should something more be done? I have the head of, så ofcause this is at the shop for a rebiult/check. But what could have caused the rings to brake (wrong oil or wear out or something else) and should new rings just be fitted or is there something else to be aware of?
