Project 750li | Part 2: Top End Refresh

Welcome back to Project 750li! In this episode we begin the top end refresh with new spark plugs, new O2 sensors, replace a busted PCV pipe, and refresh the engine air filters. This is all preventative maintenance, with the exception of the O2 sensors which are throwing a CEL and codes. There is lots more wrenching--and projects--for this car, so stay tuned for new episodes! Shout out to ‪@fcpeuro‬ for always having the parts I need. As always, thank you for watching.
