[Solved] Desperately Trying to Find What's Wrong with my Engine
Car: 2016 Subaru Legacy Premium
Long Story Short: I changed oil myself, was stupid only put 1/5th of what it needed, proceeded to drive it for 20 minutes, car dies. Pulled over, find out it needs oil so I fill it. Has trouble starting up but it runs enough to get me home (5-10 minutes). Starts up fine in the morning, so I drive it, dies after 5 minutes on the road. Tow to a repair shop, they say Engine's burning oil way too fast, after a "thorough inspection" ($$) they don't know specifics nor what to fix so they say "We have a used engine 50,000 miles for 6,200."
Fresh Battery, replaced myself 5 weeks prior but MIGHT'VE blown a fuse or two
Had/has enough gasoline
Used the correct oil and filter
No leaks were found
The mechanics only could tell me that the engine was burning oil too fast. I asked for clarification and they couldn't give me any!
Any help would be greatly appreciated, I'm looking at nearly $7,000 at the dealership for a new engine including labor and other necessary parts 🙁
Thank you for your time!
Driving for 20 minutes with 1/5th of the required oil quantity = goodbye engine.
Didn’t you have any warning lights turn on while you were driving, saying the oil pressure is too low? Or the engine overheating? Or CEL illuminating? Any burning smell?
It’s time for a new engine/car, I’m afraid.
Out of curiosity, did you tell the repair shop about the snafu?
I agree engine is probably damaged 1/5 th the oil so 1 quart in a 5 quart system? you could do a compression and leak down test to confirm
There are ways to test and view engines, from wet and dry compression tests to a visual examination of cylinders with a boroscope.
If your engine is aluminum, as most are, well, that's a soft metal easily damaged by heat and friction. 20 minutes is enough to damage it.
And, given that the Subaru Legacy has a horizontal layout of pistons (Boxer Engine), there's a tendency for poor maintenance, intended or otherwise, to result in a blown head gasket.
Given the information we have, Chuck is right. A good used low-mile engine, with a warranty, imported, may be the best choice, presuming that the ECM can be programmed to accept it.
