04 Sti

Default 04 sti flooded engine with oil :/

so my turbo went out on me a few weeks ago and this week i finally got a used turbo. i put it the car and started it up and after a few minutes i notice that im dumping a ridiculous amount of oil. so i found a kink in the oil line out off the bottom of the turbo. which then forced all of my incoming oil into the intake side and the burned thru the engine, about 2 quarts only ran for 10-15 mins. after i fixed this problem i let alot of the oil burn out but right now it still smokes and in 5th and 6th gear im gettting alot of shudder in the car after positive manifold pressure also.....what would you do in this situation? what would cause the shudder and what prcausions would you take? any input helps

Still too much oil in the intake, sorry to say but kinking the line is all you my friend. Had you not done that this wouldnt have happened. You gotta check things like that before you start it.

Its gonna smoke for a while, no way around that. Run it for a while then buy some choke cleaner. Remove the intercooler and open the throttle plate and spray some in. This will help break up the oil and make it easier for it to run through the engine and burn off quickly. Also try cleaning out the intercooler as oil takes a while to get cleared out of it on its own.

Definitely pull the intercooler and flush that sucker out with chemicals and soapy water. Clean the MAF sensor as well. It's going to take along time to burn completely out of the exhaust.

And at least pull the plugs and check for fouling or possibly replace if you actually burned that much oil.
