Possible oil working its way into the system, more blowby from your rings.

 

[joey17]

so maybe time for new pistons and rings?

Why everyone jumps straight to pistons and blown turbos?!!! You see this tiny hose that goes from valve cover to air intake? See oil in it?

Put an inline filter in it and you'll see it'll get soaked in oil after 600 miles. That's the most likely cause.

ok well i kind of like a breather could i do one of those or would it spray my motor with oil

There's lots of people sporting breathers on DSM's, but it's not the correct way to vent the crankcase. It will contaminate your oil with blowby pollutants faster having it plumbed that way (what the PCV system is designed to prevent), not to mention you are introducing unmetered air into your intake. To do it right, you need to stick one of these suckers in between the PCV valve and the intake:
Check Valves - US Plastic Corporation
This guarantees that your PCV valve will never blow pressurized air into your crankcase. Then make sure you have your other hose going from the the left side of your valve cover into your intake pipe. If you're getting that much oil in your lines, you can stick a sealed catch can in between valve cover and intake pipe. Personally, I've never bothered installing one though.

 

[joey17]

so what is that check valve spose to do?

 

[lacroixdp]

That check valve prevents boost from going into your crankcase from a leaky PCV valve. It is getting harder and harder to find PCV valves that don't leak from the get-go... I've even had OEM Mitsu PCV valves leak fresh out of the box.

 

[joey17]

so if i get a check valve it will help all the blow by

I guess my suggestion for this small problem, would be simply use a "Catch Can" for the valve cover vacuum hose that goes to the intake pipe. Worked for me, no more oil in the IC or Pipes.

ok well maybe ill try that. thanks guys for all ## help
