Oil in my pcv hose am i SOL
2010 nox v6 129000 miles it’s a repo I bought at an auction I put 15k miles on it since i bought it in August I uber part time and I’m dad the taxi all the time. I jus had the plugs changed before a holiday road tripped I used champion platinum plugs now my check engine light is flashing but their was oil in my pcv valve hose I broke it by accident. I also had oil in the section that connects to the air filter not oil in the air filter what’s going on I think the engine was replaced because there was a little note in the manual stating “new engine 101k miles” I think I need to use the oem plugs my buddy who did the sparks is saying it’s that pcv area incorrect air flow what should I do my coil boots look fine btw

Perhaps your PCV valve was not working or was carbonized and the oil fumes were backing up into the other PCV hose that goes from the top of your engine, and get sucked into the throttle body before the air filter. This is why the MAP sensor is near the air filter, because engine oil fumes would destroy it..
You are going to have to have to do a cylinder leak-down pressure test to find out if you have an issue with combustion chamber fumes that are pressurizing your motor too much, and you should have been seeing a loss of power and gas mileage, and likely burning oil, if so. That your motor was replaced so soon is not a good sign at all as well. Modern engines will double that mileage easy these days unless owners don’t do any proper maintenance on them. .
