    Gas Smell in Oil

    Hello, I just purchased my first wrx. Its a 2002 with a Vf34 turbo with exhaust, clutch, and suspension mods. I came to find a gas smell in my oil so i changed the oil but the smell is still slightly there. I'm running fully synthetic 5w30. How serious of a problem do i have here. Thanks in advance for all the info. Please help, this is stressing me out.

    Also have check engine light popping up on vf34 93V1.3 map.
    The code reads small emissions leak.

    hmm seems like fuel is getting past your piston rings...could be time to invest on getting some new ones it would seem though would mean u should get the bores re-honed if you do so

    however thats the most obvious reason and just my opinion dont rush out n start throwing money at it

    A slight gas smell is normal. How many miles since the last change (don't go over 3500, regardless if synthetic or not)

    When you change your oil again, send a sample to blackstonelabs.com to see if you have a "safe" amount in there before dumping $$ into it. Go to the website and order a free kit, then when you send it in, it's like $22 for an analysis.

    Take the car in and get a professional tune. OTS maps run rich. Not as rich as stock but still rich. Also try cleaning the MAF sensor.

    What would cleaning the MAF do Ron ? Doesn't the ECU compensate for the fuel ?

    not if it's getting a false airflow reading. If the thermistor wire in the maf is dirty, the airflow reading becomes inaccurate, and the fuel compensation becomes skewed, sometimes quite dramatically.

    mass air flow meter, it's located in the intake track, right at the airbox portion of the inlet tube. IIIRC, two screws hold it in. Get some MAF cleaner (don't use brake cleaner or carb cleaner!) take the maf out, remove the oring seal CAREFULLY, clean the MAF with the spray, let air dry (only takes a minute or two) reinstall the oring, reinstall the maf, reconnect.

    try it out.
