Warning tone under hood of subaru forester and burning smell

SOURCE: I have a 96 Subaru Impreza, Is smell like burning

Your car is 13 years old. It is possible for the seal to actually wear a groove into the crank shaft or cam shaft end. Which ever is protruding and has a seal. It used to happen on all the older G.M. cars. (60's 70's). Usually with over 100K miles. You may be leaking just enough for the wind to blow the oil back onto the exhaust while driving. I've seen it, done it, and repaired it. One way to tell is to look for tiny oil spot on the lower part of the rear bumper or lower part of trunk lid. Oil sometimes will blow back that far. Now, even if they change the seal, it may not stop the leak. Back in the day, you used to be able to buy a "Sleeve" kit for the crank. It slides over where the groove is so the seal can make contact on an smooth, level surface.
Get a second opinion before moving forward. And be sure to get some sort of warranty if at all possible.
A long shot, see if a mechanic will put it up in the air on a lift and show you where it's leaking from. It should be pretty well spread out over the bottom of the motor and possibly the transmission.

Good Luck and I hope this helps.

On mine, I got under there and there are rocks rattling in the heat shield. There are factory made holes in it, and the rocks sit in there like eggs in a carton and rattle when the engine hits a certain vibration frequency which is basically when it is at a stop light or idling. The repair shop wanted to charge to cut them off but I think I am going to drill bigger holes so the rocks fall out, as they are pretty tiny.

Check the cap and rotor for internal carbon tracking or, just change them. Also, take a look at the coil when its dark and rainy and see if there is any arcing where the coil wire goes into it.

Please have your exaust pipes checked, perhaps a mount is burning. The catalytic converter can make a nasty odor when it is clogged. Check the wear on the serpintine belt.

no not nornal,you need to get it plugged in to a diagnostic computer to see which sensor set it off it means you have something that needs to be looked at,low oil could be a coincidence
