my k&n is screwing up my maf what can i do
Interesting. I'm NOT running a K&N on my daily, but recently noticed my mileage decreasing. I pulled the MAF and it was oily, as was the air cleaner box and the tube going to the TB. The only thing I could think of was I had recently run a 3M engine cleaner through the intake, and I figured some might have stayed in there. However, that's mostly water and alcohol, so IDK.If you're fouling the MAF with oil, and it's not coming from the K&N filter, you have a problem that may not be fixable.
You also might have a bad check valve on the Opti harness, that could push oil up into the elbow.
You get more fine, particulate matter introduced into the oil and rotating assembly. In addition to oiling the filters (and as mentioned, not overdoing it), 2 ankle high cheapo drugstore stockings pulled snug over the filter keeps a lot of funk from getting in w/out impairing intake flow. Or you can spend more money on a fancy condom for it. Leggs work just fine for me.So then if you run with a filter that is NOT K&N, or a K&N with no oil on it, what happens?
i think there was 2 vacuum lines, one from the intake down to the opti and one from the opti to the intake tube (elbow). There were 2 check valves, blue and white, I took them off along with the vacuum lines and blew air through them to make sure they worked properly, air one way not the other. Mine were clean and worked. Just good maintenance i guess.Personally, I haven't noticed my car consuming ANY oil whatsoever. I never have to top it off between oil changes, and there is no smoke.
