Default Car eating an unusual ammout of oil

Ok, I have a 99' Rs and it eats about a quart every 1000 miles, maybe more. I have about 55'000 miles one it and have an intake and exhaust. I took it to the dealer and they said they didn't find any leaks (which there isn't) and they said they hooked up a scaner to the exhaust and didn't get any oil comming out of it. They took apart my intake and said there was oil just laying in the throttle body!!!! They said they got warnings from subaru about the intakes. They told me to keep an eye on it and bring it back if it gets worse. Well it's still eating oil and I cleaned the intake and changed the hoses for the intake. I checked the trottle body and there is no oil build up but it's still eating oil??? Where is it going and why won't the subaru dealer fix my car??? My friend did a Gsr motor swap on his civic and he had oil in his throttle body and his rings were shot. Is this what's wrong with my car? And how can I get it fixed under warrenty. I payed like $1,500 for the extended warrenty seems like it's a waste.

Its possible it might be the rings or piston,but first I'd buy a new PCV valve and see if it gets better. If problem remains have compression & leakdown test done to see if its one of the pistons.

Sounds like oil is blowing by the rings and getting in your intake track. The other thing is, did the dealership test for oil in the exhaust under load? Just revving the engine while it's sitting registers barely any load and the oil will blow by worse under heavy load. Don't hammer on the car until you get the problem figured out. I would do as they suggested above.

OK, been here before... 1 qt/1000 mi is within factory spec (it sucks but it is). Some EJ25s had a bad batch of blocks that deformed over time and egg-shaped the cylinder walls. I had my block replaced at 60000 under warantee due to 2 cylinders being out of round. Get in touch with your dealer NOW!!! They will likely give you crap but they will need to establish an oil consumption log on your car which basically consists of an oil change and milage check and then you'll go back to the dealer at set intervals for an oil level check. Get this on the record before your 60k powertrain expires. Other than turbo/supercharer there is not a single bolt on that can be considered a cause... its bad metalurgy.

Although it sounds like the dealer is setting up to blame the intake.
You might consider swapping the stock intake/exhaust back on for a while.

It does sound like they are going to do that, but they are usually cool with that stuff. As a matter of fact my car is there now because my rear O2 sensor went. They have also replaced my friends o2 sensor even though he had a safc. Do you guys know of any hard proof that the intake wouldn't cause that? I know there is no way but if there is a way I could prove it I wouldn't have to put the stock air box back on.

Or does anyone know of a mod friendly Subaru dealer that wouldn't screw me around and fix my motor? I'm in Pa near Philly.

Ill tell ya what, I was the first in my area to buy 2.5rs(back in Sept '97) and I had a simular prob. I hate my dealership(Apple Subaru York,Pa) but thats another story. They told me the same thing (burning 1qt every 1000mi is the norm).I didnt find any in the intake but then again I never looked. I finally blew the engine at 49,550mi, just inside of the factory warrentee(close one ).
I ended traveling 50mi to another dealership who took care of everything no questions ask and they treated me like a PERSON (sorry had to vent). Anyway had the block replaced and I check the oil every so often and really had no problems since. So yes It could have been a bad batch of blocks or something. Make sure its taken care of before warrentee runs out, would of cost me $1900.

sti27 where did you end up taking your car? I'm about an hour and a half or so away, but if I can get my motor fixed I'll drive the distance.

I see there is a mention of an oil consumption log. I have heard of this before but am not quite sure how it works. Does the dealer simply monitor your oil changes and how much oil you have left in your car at the change, and from that information determine to what extent your car is damaged or what is damaged (ie: cylinder walls, piston rings, etc...) Basically like a trial and error thing or is it more involved?

I took mine to Hanover Subaru (I forget the name). I also heard Lancater Subaru is pretty cool. I was in Lancaster one day and had a CEL light up. I called L.S. and they were really nice on the phone.
Where are you from?

JohnP555, I live ~120mi from the nearest dealer (awesome dealer, the drive sux balls though) so what they did for me may be a bit different than if you're closer but...

- Went in, had oil changed and logged and told don't touch it
- Went back in 1500 or 2000 mi (don't remember which) and checked again... oil was very low but technically still "within spec"
- Dealer called in District service guy since it was his call to make such a potentially large decission
- District guy (who loved the mods on my car ) took the car out for a 180 mi road trip after giving it oil/logging it.
- District guy came back, measured the oil, noticed a loss (albeit a small loss), metioned again how much he loved the car and wrote up a warantee ticket for the block

92 legacy turbo? If so put the money into it, if not then yes it needs a new block or a rebore and matched pistons or a new set of rings, or a seal(s)... then again I haven't heard of the older EJ22s having this specific (egg-shaped cyl) problem. I assume you've checked the PCV valve, the valve cover breathers, etc to see where the oil is coming from? Look at your tailpipe, black deposits are usually unburnt fuel/carbon (which isn't always a bad thing) but if its oily then you've found your problem, your getting excessive blowby from something. Depending on milage it could be bad rings/seals in the motor, it could be the egg-shaped cyl walls, either way its gonna cost you. If I were you I'd start buying cheaper oil and check/refil frequently.
