Default Excessive oil consumption during break in or not?

Just had short block and other engine parts such as cams, valve shims etc... replaced on my 2012 Subaru through warranty due to excessive oil consumption. Has about 800 miles on it since replacement and I just checked oil to find it barely is on minimum hole on dipstick after letting sit for 10 minutes. Is this normal for break in or out of the ordinary? I will wait for engine to completely cool and add to full mark, or do oil change if necessary.

I would say some oil consumption during break in is normal.
But almost a qt at 1000 mile is still pretty high.

yeah that seems a bit excessive. but not totally out of the ordinary.

What did Subaru say for break in? did they just hand you the car and send you on your merry way?

I just replaced the engine in a 2009 Forester with the EJ253 and even doing a bunch of engine braking to seat the rings it only burned maybe 1/4 of a quart.

I'd check the PCV valve. That's supposed to be checked during the oil consumption test, but I don't think most techs are going to get into it for what Subaru pays.

PCV valve is an easy check, and they are cheap to just replace.

After that it's removing the intercooler and the downpipe (possibly headers) to track down where the oil is coming from. After that, it's compression and leak-down time to try and narrow down the search.

As others have said, and I agree, that is excessive even for break-in.

The Subaru dipstick is also pretty terrible, so you want to be very sure that when you're checking the oil, you do it EXACTLY the same way every time to try and reduce the variables that can cause inconsistent readings.

You want to set yourself up for repeatable and accurate feedback if this ends up getting messy with the dealer. You're likely in this for a couple of thousand miles more before anything would actually 'happen' with a repair, so document what you do and make sure you're staying in contact with the dealer just to let them know and further document your observations.

This is very true. Especially if checking cold oil after you have shut down the engine. I normally check the oil after it has sat over night.
