    Damn I post a lot, but I'm new to the fa20. Anyways I noticed today when I started my car after it sat for 2hrs it puffed blue smoke, I know it's oil. Just curious if it's normal? I do also smell oil when sitting at stop lights. But that started after I changed the oil to Valvoline. Mods are just a map intake and tune.

    Get a compression test, blue smoke isn't normal for any healthy engine.

    Unless it is world rally blue smoke. Then it’s Subaru brand exhaust smoke.

    Don’t feel bad about posting a lot and asking legitimate questions for ideas. That is what this forum is for IMO. I second the compression test and am praying for you. Have you checked your oil recently? Maybe take a look to see if it is still full

    Maybe the turbo is failing or leaking?

    That's where my thoughts went, too.

    Massive blow by equals massive gains bro!? I honestly don’t miss having a turbocharged Subaru.

    If it is a turbocharged FA20 then I would deff lean towards and issue with an oil seal in the turbo. Had his happen on my vf37 on my 2002 WRX I had it on. Bought the seal/rebuild kit off the interwebz for it and then took the turbo to https://dieselcomponentsinc.com/services/turbocharger-repair/ for balancing.

    Ok thanks for the ideas guys, I'll dig into it more once it warms up. I haven't lost a lot of oil since the change last October or early November.

    As I am sure you are aware does not take much oil somewhere real hot to make alot of smoke.
