I just replaced my charcoal vapor canister on my 95 BMW 525i with 111,000 miles. Would a defective canister affect UOA? My last two UOA from Blackstone showed fuel dilution issues. Crankcase ventilation was suspected.
Yesterday I replaced my plugs after 31,000 miles. All were worn normally with thin light tan deposits. I also use FP60 and mostly Chevron 93 octane.
Of course I could have one or more bad coils or fuel injection issues. Just trying to eliminate potential issues. TIA
