Update. Removed cold enrichment above 50C Reduced cold settings up to 50C. Fitted a wideband and tuned cruise cells from 13:1 to around 15:1-15.5:1 while doing 1200 highway kms driving to work for a week. Latest sample has come back with high dilution again. Every other time I've sampled mid stream while draining but this time sucked through dipstick tube and may have sucked off the top section of oil as it was 5.9% from 1200km which is the worst sample so far. Next step is to swap out injectors and re-check
New engine Def not running rich Cams are mild One of the injectors is ticking so most likely that's the culprit but I don't wanna upgrade to top feeds unless I'm sure.
Already done start of the year. Also had them cleaned. Tried winding Cas while spraying individually into a bottle and all spray pattern looked good. Replaced o-rings and refitted but still dilution. Bought a wideband. Removed cold start enrichment and leaned out at cruise Still dilution [emoji15] Time to swap out injectors...
