A bit of a chat with @Paul Bryant will probably be a good start.

But I'd want to know how the Lambda circuit works. Used to be that engines were designed to run a bit rich and then the O2 sensors would make them lean to comply with limits. Some (many?) are now designed to run VERY lean and the O2 sensors enrichen to stop damage. Some are set to default to AFR18-ish. That means burnt and bent valve gear. @RICHARD ALBANS may know? - My guess is you'll need a PCV.
