Default p0011 CEL, known poor maintenance

So there are a ton of threads on p0011 being due to oil starvation, poor maintenance, etc. I bought an 08 hatch about 10k mi ago. The previous owner had apparently (according to the local dealership) gone 10k miles between oil changes and ended up with a spun bearing. Subaru replaced the long block under warranty (not sure why). The long block was replaced 1k mi before I bought the car so I figured the guy couldn't have done much damage to it between then and when I bought it.

Since I bought it the oil has been changed every 3-3.5k mi with rotella t and subaru filters. The car consumes oil at about 0.5-1qt/3k mi, and I am pretty sure that is within the range that subaru calls "normal". The car has had no issues since I bought it. Before I bought it I talked to the dealership that did the warranty work and they said there was no damage to the heads or turbo (I specifically asked about both) when they tore down the engine.

Now the p0011 light just came on tonight so the car is parked until I can get to it later this week. Is it likely that it is just the turbo going? I would have to imagine that subaru would have at least cleaned any sludge out of the heads, oil lines, turbo, etc. after replacing the long block. Is that a poor assumption? Should I be assuming that the entire motor is going? I plan on looking at/removing the AVCS oil line filters since I don't know if that has been done. I am guessing I should probably pull the turbo and see if there is anything obvious in there. Anything else I should look at?

id bet that the engine was not swapped or the guy who sold it to you swapped the new motor out or some crazy **** like that

the engine should still be under warranty from the dealer

If it is just the p0011 code is it likely to be oil related? It seems that a lot of the people who have starvation issues are getting both p0011 and p0012.

I can't confirm, other than talking to the dealership, that the engine was actually swapped out. But I am pretty much 100% sure that if they did swap it out the guy did not pull the new motor afterwards as he didn't seem to have a mechanical bone in his body.

Any quick things I can check before calling the dealership and seeing if they will take a look at it as it is an engine they just swapped?

One other thing, not sure if it's related, is that the gas mileage has been getting worse over the last couple hundred miles. Worse like 24mpg down to 20-21mpg. If the AVCS solenoid had failed could it cause this?

I had a Forester XT and that code was present when I bought it.

I removed the screens on the AVCS banjo bolts, changed the oil and filter religiously and had zero problem when my mother was driving it.

Once my brother got a hold of it, he drove it for a good 3 months before he blew the turbo driving like an asshat.

Replaced the turbo and 20 miles later the solid replacement turbo blew. Funny thing is I checked the oil feed to the turbo before installing it, and it was functioning really well, I have no idea why the new turbo went out so damn easily.

I've heard from the Subaru dealer that one guy had his EJ255 go through 3 TD04s, all dealer installed within 150 miles. A vendor I work with, his wife has an OBXT and that turbo just went too.

**** EJ255s, I'm done with them. The AVCS and turbo oiling systems are a huge failure in these motors.

^ Dam AVCS causes so many problems


I highly doubt they replaced the full long block... most dealers around me would just reman the short block and clean the heads. Back on topic...

That's an oil starvation code. Going 10k miles is way too long (assuming you meant a hatch WRX, not the impreza). I would have them check your AVCS to see if the screens are clogged or something. Hopefully they figure it out soon!

If it was done under warranty they would not reman it them selves at the dealership....they might put a remaned long block in it...but it would be a replacement unit....that's the way dealerships operate....that's there standard operating procedure...
