So I have been noticing a trend that I lose about 1qt of oil after about 1500-2000. I look under my car and don't see any oil and the ground where I park doesnt have any noticeable oil stains. Any idea whats going on? Is it my vf39 thats burning it? I dont see any smoke coming from it so im just unsure. Looking for ideas that I can check. I had my valve covers replaced last year and I replaced the turbo return line (what a PIT!) about 6months ago.

Thanks!

is there oil all around your drain plug or case, but they never drop?

Some of that is normal consumption. The excess stuff could be coming out in a few places.

Turbo seals is a big one. Valve covers is very common. You had your replaced... have you been under there to check them? I know that's where I'm loosing some of mine. And old beat up seals in the motor.

I go through a quarter every 1000 miles. Old motor. I just keep filling it up. If I had a newer motor I'd be concerned.

Check the valve covers.


How's your power output and your MPG been?

I probably go through a quart in 2k miles but my turbo center shaft seal is out.

how were you able to verify this?

Think my dads outback xt could be in trouble.

Theres usually a drop of oil sitting on the bottom of the oil filter, ive read its usually just a really small leak in the oil cooler that causes it though. I dont think it would cause the amount ive been having.

Its pretty much the same. Usually get around 18-20mpg

Try a synthetic blend or conventional oil? My old performance shop in Colorado (Revolutions Performance) always recommended a high quality conventional oil to all Subarus, and they carry a pretty high Subaru rep.

Im pretty comfortable with what im using now. There are plent of oil analyses that show it works well with our EJs

When the weather gets cold, sometimes the oil sticks into the breather lines that bolt to the intercooler. Pop the hoses off and see if there is a buildup in the hard line. If there is a buildup its nothing to worry about, it happens because the car doesn't go on long drives. It'll look like a wax substance.

+1 you are right on point with the its going to be turbo seals and normal burn off. My car burns 1 qt every 2000 my turbo seal are done

only burning on vacuum. But no oil on start up. Headers were clean when removed.
