Oil disappearing

[Clockwerk]

03 Nissan Murano, 60k miles..

For whatever reason, this thing EATS oil. Over 1k, I went though 5 quarts. It doesn't smoke, sounds like its running fine (till the oil is low and I can hear the cams). I park in the same place everyday and there is no sign of oil leaks. No weird smells, nothing.

5 quarts over 1000 miles?!?! thats fucked up.

Maybe it's going into the cooling system. Put some clean newspaper underneath the car overnight and see what happens.

Strange. That's a lot of oil and it went somewhere. Can't imagine you are burning it or you'd know it.

Seems like a lot even for escaping into the cooling system, but if it is it will show itself easily if you check the coolant. A lot of oil in it should be obvious.

Doe the oil look like caffe latte'?

Maybe leave it idling for 10 minutes when you park it and see if you see a leak then? That is, it may only leak under pressure.

I have heard stories online of Muranos having similar problems... I would think about dumping it.

Check the coolant. If it's brown or "milk shake" like, then you have head-gasket issues. Even if it were leaking only under pressure anything that caused you to lose 5 quarts in 1,000 miles would leave the engine so soaked with oil that it would be obvious there was a leak. You'd see the leak trailing down your driveway.

Check the trans fluid too. If the diaphragm valve failed, oil could be sucked into the trany.

i had a mustang that did the same thing. the pcv valve was clogged and the oil was shooting out the dipstick and blowing over the road. never leaked on the driveway. odd.
