• Subaru Liberty (Legacy) burning oil (?)
    6 replies, posted
So, stupidly, a week or so ago I accidentally put too much oil in my car. I only drove about 200 meters and ended up having to drain my car on the side of the road to get rid of it. Refilled the oil to the correct level and drove off. There was still smoke coming out for a bit until the engine had seemingly burnt away what had gotten on the engine itself and there was no more smoke coming out. Since then, I have done about 150km. Yesterday when I went down to the park to take a picture of it, I noticed there was smoke coming from it, a blueish colour, indicating that it was most likely burning oil again. I have a [URL="http://www.youtube.com/watch?v=D29h8W0vPcg"]video here[/URL]so anyone might be able to help out on this. What can I do about this, and is there a way to fix it that won't break the bank.
The most common cause for burning oil is old, brittle and dried up valve stem seals They look like this: [t]http://www.gmcmotorsport.co.uk/images/uploads/stemseal.jpg[/t] They are a fucking bitch to replace but they're not expensive.
Usually if it is valve stem seals it will only burn oil when it has sat for a few hours or overnight. I need to do mine on my vette if I keep them. Just keep an eye on the color of your coolant, oil, oil level, pressure, and temps.

My friend's Volvo used half a liter of oil each day until we put a rubber moisturizer in the oil. Now it uses about a liter per week instead :v:
How much oil do you consider too much? In my Ej22, i can add 1/2qt+ over full with no issues What oil do you use? Some oils tend to burn like crazy in Boxer engines I havent heard of too many people having issues with valve guide seals in Subarus, usually the things that leak are: piston rings, crank seal, and cam seals. The crank/cam seals would be leaking into the timing cover, maybe leaking out of it depending how good the timing covers gasket is. Of course, piston rings would burn oil like in the video, but i doubt theyd go bad that fast.
99 dakota with 3.9l and 258,000 miles, burns no oil per every 3k oil change :D
Just check the dipstick every day or so.. my Olds Aurora puffed some blue at startup, but the oil level never dropped. If yours doesn't drop, don't sweat it.
