So I have 2003 wrx and the exhaust is getting oil in it. So maybe my turbo is messed up or could it be pistons? The head gaskets are pretty new only 3 months old and the turbo is a deadbolt monster td04

So just check the manifolds or do I have to pull the damn engine apart again?
A compression test is a pretty simple way to determine if your pistons or piston rings are donezo. Consult your shop manual for specifics, but normal compression should be anywhere between 140-160 psi. If you have low compression in any cylinder, squirt some oil into the cylinder (~2 teaspoons) and recheck compression. If the compression increases considerably after the second run, your piston isn't making a proper seal (piston rings) and is likely responsible for the oil burning. If you have normal compression and you are not leaking oil from the valve cover, I would suspect the turbo.

I have perfect compression/leakdown, and my engine is chewing through oil.
Do you have forged pistons?

I should also mention that my car doesn't seem to put out more than 7psi (read from a boost gauge plugged in near the throttle body) and it makes a ticking noise when it's on not to mention the car is incredibly loud. I'm at 140k but I bought the car at 135k. I've changed the oil and I am going to change it again soon.
Well duh
Rings were not installed correctly..
Think my rings went bad?
One of many possibilities.. my exhaust has no oil in it, no leaks, no smoke, consumes nearly a quart every 200 miles.
That doesn't count! HahaWell duh

Guess I have to find out the hard way. I'm just surprised because it doesn't seem like the car is losing any.
If it doesn't seem to be losing oil, why worry about it? Are you sure it's oil that's in the exhaust? If it's black and dry, like graphite powder, that's carbon, not oil.
It's wet sometimes and it's dry other times but the ticking and loss of pressure is what concerns me. I know there's definitely something wrong there.
