I went out and broke in my new clutch and took it to its first drift event but after each oil change ( which i did very often..like 30 miles or so bc i was afraid of tearing it up) it still smelled of gas after a few miles.. the oil that is. I took the fuel rail out and primed it and didnt see any obvious leaks. at this point i am thinking injectors or tune. What do you guys think? as far as the tune it runs great though so that makes me lean more towards injectors but who knows lol.

Since there isnt any leak on the fuel rail and injectors, then it could be other things like bad fpr or bad tune. Do you have a wideband and fuel pressure gauge? If you do, what are your afr and fuel pressure? Dont assume it's good not know your afr.

Would have to be blow-by bad enough that you'd notice serious compression problems; power loss etc.

Pull the rail, turn the key to acc mode, see if the injectors leak.

What are your AFR's? A car running 10:1 AFR will still run well, albeit pumping fuel into your oil.

fuel in oil means that your running dangerously rich man so id get that ecu tuned and a afr should of been the first thing you buy with any turbo setup.

if he was running THAT rich it should be really obvious and noticable. IE: flames from exhaust in every gear.. agreed though AFR and FPR is always first priority
