Default Noise coming from turbo?

Just bought an 07 wrx bone stock. 125k miles not sure if the turbo has been replaced but when I rev up I hear a rattle coming from what I'm assuming is inside the turbo. I took the intercooler off and saw some drippage underneath where the intercooler hooks to the turbo. I have clean oil in the intercooler, intake, and turbo. Also when I was driving back from where I bought the car I threw an engine light and my cruise control started to flash. Code was waste gate solenoid. The turbo doesn't have any play on the engine side, didn't get to the exhaust end yet. Any info would be awesome.

It was what I thought was a "deal" at the time. Drove a little over 3 hours it was sold as is. I called the dealership to let them know they haven't gotten back to me. Have a feeling I'm screwed. I was thinking it could be the waste gate cap inside the turbo since there's no shaft play, or the exhaust end of the turbo.

Wastegate code is usually an over boost code, im not positive. But if there's a consider amount of oil by turbo and in the intercooler I say the seals are toast.

It could be lots of things. I don't think that the wastegate solenoid code and the oil in the intercooler are related. Sometimes a clogged PCV valve can cause oil to leak through the turbo compressor, but not in as large quantities as you are describing. It does not sound like a cheap fix. You might want to fill out your profile so other members can recommend places to take it to. Don't blindly go throwing parts at it. You need to get compression / leakdown tests done to see if your motor is borked. If it is, you can end up replacing turbos, PCV valves, boost control solenoids, etc. until your bank account it empty.

Most states have lemon laws, but I'm not sure if you signed a waiver to waive any responsibility of the dealership. Read any documents you signed, and try to find out if there's any way you can bring this car back.

Usually when people think it's the turbo seals, it's the motor. Turbo seals is just what everyone hopes it is.

The car runs fine, boosts to where it should, and was just below the oil line after the 3 hour drive. Maybe I made it seem like there was more than there is.

There definitely should not be enough oil coming out of the turbo compressor for it to be dripping. Sometimes a clicking sound under the turbo, if it coincides with engine pulses, is due to a leaky up-pipe, or up-pipe gasket seal.

I would definitely pull the intercooler, clean it thoroughly, and pull the PCV valve. If it rattles, it's ok, but I'd clean it out with some carb cleaner while you've got it out. If it doesn't rattle, then it was probably gummed up. You can clean and reinstall it, but it's cheap enough to replace.

You might want to change the BCS if you're getting a wastegate solenoid code. I think I may still have mine in a closet somewhere. Keep an eye on your oil consumption, and look out for smoke from the tailpipe.

Tailpipe is good smells fine no burning oil. And where it was dripping I have a feeling these nimrods at the dealership didn't put it on tight when they sprayed everything down to make it shine for the sale. Ill clean it up and do what you recommend and get back to you with some feedback.

Fill out your profile.

Also, find a good tuner/shop/buddies that know Subaru's and take the car to them immediately.

Heat shield on the uppipe, after cleaning the oil I had only a small amount after a few weeks back in my intercooler, must of just never been cleaned before.
