Burning oil

**transamgirl89** · 05-15-2010, 02:36 PM

So I know I'm due for an oil change and yesterday I went to check my fluid levels and I noticed my oil is way low. I checked it again and it was right at the lowest hole on the dipstick so now there must be a leak somewhere. I know it's not going to my exhaust b/c there's no black smoke when I gun it. Only thing I can think of is maybe it's leaking into a gasket or something. I checked the oil pan and filter and they are fine, no drips or anything. I'm praying it's not a bad ring that I have to strip the engine down to the pistons cause I don't have that kind of time or money. Any advice would be helpful.

If you have the stock breather system, it's sucking it into the intake manifold...Common problem on these...

Even on a V6?

Yep... blue smoke is typically oil, not black

I noticed that my 5.3L Yukon was going through a little over a quart every oil change (4-5k miles, ALOT of highway). Left my mom's one day, fired the truck up, and was brought to my attention, a little blue puff came out upon a hot start. I've noticed it two other times, upon leaving stoplights, far and few between, but it occasionally does puff. Weird, because it would seem to me that it's alot of oil it's burning, yet I rarely ever see it.

Rings, valve seals, could be a myriad of things really. Holding good oil pressure at a hot idle in gear? How about 3k RPMs and up? A good way to tell is to fire it up cold, run up to the local convenience store, shut the car off, go in and buy a soda (or beer

), start it back up, and drive it back home and roll through the gears.... all while having a friend follow behind you. It's good to know when it smokes and what the car is doing at that point in time to further go into detail.

Sorry, that's the best I can do, just from my own personal experience

Have you checked the oil pressure sender to see if it isn't cracked/leaking?

I think I've figured out where it's going. I'm pretty sure it's leaking into the coolant so I'm gonna flush it and put some prestone and a coolant additive since I had that oh so wonderful dexcool crap in there which is hard on our gaskets so it may be as simple as a bad gasket seal which isn't a big deal. And I'm going to start using 5w-30 oil instead of 10w-30 and see how that goes. Can't believe an oil change here is $75 for synthetic! Back home it was 54 but this is Atlanta after all and I have no way of changing it myself since I'm in college housing.
