oil flooded the intake/throttle body - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

lx93 · 12-13-2015, 03:58 PM

okay long story short i messed up the PCV system and got oil all sucked into the intake and behind the throttle plate. I also have a Vortech SC v2 setup(which is the culprit, because it can never drain right and i was messing with the crankcase pressure valve to try fix it).

so the question is, is my engine completely fucked? i mean, there was oil pouring out when i poke open the throttle plate.

Turn the engine manually (push it in gear) and make sure it is not hydrolocked before you try to crank it.

If you got enough oil in any cylinder to hydrolock it, then cranking it could bend a rod.

If not, it should be fine once you get it cleared out, but you probably fouled your MAF sensor.

Pull your Plugs and crank it over, I would suggest pulling the intake and cleaning it out if it truly is full. Remove all hoses and clean them too, Check the brake booster also to make sure oil didn't get to it. You can spray carb cleaner down the intake ports to help flush it out if you get a friend to crank it while you spray... Its a lot of work but saves the motor. Clean all sensors with a contact cleaner not carb cleaner. NOTE make sure you disconnect fuel pump and remove the coil packs and plugs if you crank it over!!!!!

I'd just throw a ratchet on the harmonic balancer mount bolt and slowly crank it through a couple revs.

The guys are right about the MAF. Be careful cleaning it. If it starts ok then, meh, it'll smoke like hell for a bit. You might throw the P0420 code if the cat is fouled. Just reset it after a heat cycle.

If it doesn't start or misses on a cylinder or two, probably fouled plugs.

Sorry to hear your sad story

I can't advise on what you should do now but may I ask how exactly did you mess up with the PCV system? I'm also supercharged (HKS) and also facing quite a lot of oil in the intake (pic and details here):

you could do the prime procedure that lets the engine turn without firing up?
