Default 35 qtz of oil in 6k miles

Hi everyone I was finally able to make my own thread. Ok so I purchased a 2004 sti with 139k miles on november car ran great but shortly after buying it, it was out of oil. So I filled her up, week to 2 weeks later she was almost dry again. The oil disappearance is a mystery. Starting in January the car started to act funny. Rpm's would fluctuate from 1500-stalling out. Not very enjoyable. Took it to several mechanics and they told me it was my rings, I told myself well before I buy a rebuild/upgrade kit let me actually do a compression test. Did the test and the results:145,151,150,155. We also checked to see if the coil packs were fine and replaced the Spark plugs with OEM subaru ones. While doing the passenger side I realized that one of the clamps on the bottom air box had broken thus leaving the box slightly opened.

I just need help on finding out the problem to the rough idleing and the eating of oil like a hungry hippo. On another thread I was giving some tips on trouble shooting but haven't gotten to it yet. One of which I will be trying today is unplugging the maf sensor and seeing if the car still starts.

Thanks for any and all input guys and gals.

BURNING that much oil, i would think you would have an extremely obvious mechanical problem- so i would guess you're leaking it.

Wandering idle would likely indicate an intake leak.

No puddles under the car. Put it up on the lift can't find anything so maybe a turbo seal.. But than what would cause my rough idleing?

Wait so thats a quart every 170 miles. Yeah you're either hemorrhaging oil out of a massive leak, or it looks like you're fogging for mosquitoes while you drive. Or you have only dont 3.5 quarts in 6k miles which is just over a quart every 2k miles, which really isnt that bad at all.

Your pistons probably have big black mountains on them from consuming that much oil. You will need to rebuild your motor. Nothing short of a new/rebuilt motor will fix this.

Ya man, you have big problems.


Try a leak down test if you can, but you have serious issues. I wouldn't drive it until you yank that sucker and get it fixed.

It could be a stuck PCV valve. They can cause rough idle. Also problems in your vacuum lines can cause a rough idle. How's the gas mileage?

You said you changed the spark plugs. What color were the insulator tips? They should be tan. Black is not good.

Anyway it seems your crankcase is being pressurized and forcing oil out when the engine is running. Crawl under and look for places wet with oil. Wipe them dry and drive the car a few miles. A drop every 20 feet is equal to a quart every 100 miles, so it wouldn't take a very big leak.

i would check the pcv valve. it almost sounds like the crank case pressure
is pushing the oil into turbo inlet hose and then back into motor.

there should evidence of oil being burned..look at tail pipe.

There is traces of oil in the exhaust tip and can also smell it. Only time I would see smoke was under boost.

A fellow member mention to unplug the maf sensor and see if the car still starts he said if it does it means I have a vaccum leak. Now was I suppose to take the maf sensor out or just unplug it because I just unplugged it.

Op if u were burning 35q for every 6k u would of suffered catastrophic failure a long time ago and plus there would be evidence of oil leakage or smoking mosquitos/.
Now 3.5q for every 6k would be more logical.

You may want someone to follow you out for a drive. With that kind of consumption you are either leaving an EXXON Valdez trail, or you are smoking like Cheech n Chong's weed bodied van after the exhaust catches the rear quarter panel on fire. It simply is not vanishing into the 4th dimension man. There is only two possibilities here. Good luck.
