A closer look at this job

This video focuses on cleaning VANOS check-valve screens associated with BMW N52/N54 engines. The check valves are part of the oil-controlled cam-timing system. It makes sense to see the component and how it's handled, while remembering that a check-valve cleaning is not a universal cure for every cam timing code.
