Heavy oil use/pcv valve

I've been having very heavy oil usage of late, even greater than the Jeep referenced "standard" of 1 qt/1000 miles. It has resulted in my 2007 being more than 3 quarts of oil low without the idiot light even coming on. I know, check the oil more often, but really, it's a relatively new car and who really thinks they should have to check the oil every 1000 miles on a newer car.

Anyway, there's plenty of comments going around on various boards. Couple of questions if anyone wants to provide some input. Dealer service said a faulty PCV valve can cause heavy oil consumption - no I have no obvious leaks at all. Recommended to replace to PCV. Anyone have a picture of its location? I think it's tucked someplace sort of hard to find/get to. Any tips on changing it?

Bigger picture question is should I be immediately concerned about any potential engine damage already done with running low on oil before noticing it - even if the engine light never came on? I regularly change oil at 3k miles, but I had the oil pressure light ding and come on for 1 second the other day and turned right back off, so I checked the oil, finding it very low.

This type thing is the only danger with buying the first year model of a totally new design by any manufacturer... but that's must me b!+ching... I had a 93 Ranger 4X4 that was the first of it's kind and never had anything but problems out of it.

.. back to your problem. Low oil is always cause for concern.. especially on a 3(+-) year old vehicle. Don't piddle around trying to save a buck (unless someone on here has an exact answer for you). Take it to an experienced mechanic (or even better the dealer- even though it'll be expensive if you're out of warranty). Get it fixed soon, it's not worth your engine. Good luck.

Never rely on the engine oil light coming on as a warning your oil is low. When that light comes on, it's too late.

^Bingo. That's the "say goodbye to your bearings/engine" light.

ALWAYS check your oil every fill-up, or at least every other week- Mark W.
