Hey

My 325 is burning oil (blue fumes) and sounds taptaptaptap

I'm told by BMW it is the piston rings and besides it sounds like an old motor in need of a full overhaul.

but a mechanics i know tells me maybe not the rings and proposes to adjust the valves to fix the 2 problems.

Does this makes sense?

Has anyone fixed burning oil in the rear muffler with valve adjustments ?

Here it is


clean oil and does not sniff, snort or snuffle (=> not a head gasket problem)

Thank you.
