Hi, all
I have a problem on the 2005 Pacifica, I find out my engine oil keep buring, is look like half gone after 45 days... any idea what happen?
Is it the problem on the engine oil that i use? I do check the bottom of the engine, and i do not see anything came out.
Any Info & idea?
Please help.

 

If you are losing THAT much oil, it's got to be leaking somewhere. You probably wouldn't see it actually dripping out though. Are you saying there are no oil spots or stains underneath where you park it (garage, driveway, etc.)?

If you are burning oil, you would smell it and your exhaust would give off blue clouds of fumes when you accelerate substantially. So pay attention to those two things if you think that's the case, and then report back here.

 

I agree; if you were burning you would smell it for sure or otherwise you would see it dripping. I have noticed that when I change the oil on my 2005 I fill it and drive the car for a bit and check it again and it's low. After I add to bring it back up to to full it remains there until I change it. It's different than any other car I've worked on. Usually after you change the oil and refill, run the engine and add until it's full it should be fine but not with this car.

 

There's another post with this same problem. I have a 2004 with this same problem. i don't know where the oil is going but it's not in the engine. someone suggested changing the PCV valve. i'm thinking of using a heavier weight oil.

 

I have a 2005 and it's got the same problem. I took it to the dealer and they said it could be that I had synthetic oil in there. We changed it to regular oil, 5w30 and see what happens. Well, it is still losing oil, it's been a couple of changes since the dealer visit, but I think it's slowed down.
There are no considerable leaks to say of. I think it might be a main seal leak or it's just burning oil to the exhaust and I can't see it.

Anybody got any more insight on this?

 

Google is a great tool to use...

It's a well known issue on some years, including mine. Just keep an eye on the level & check it much more often or trade it in is all that ya can do, it seems....

 

mine ends up a quart low every 2500 miles or so. can't explain it.

 

I did have this problem of Oil comsumption on my PAC 04. It had 92,000km (60K miles). It did not show any oil leak.

After a few visit at the dealer where they would register the oil comsumption, they agreed to open the motor. They found a Ring on cylinder 2 broken. They changed the Ring, got the Head redone, Valve seal, and sitting (base?), bearing and cam seal (Sorry if parts name are screwed in the translation).

I was lucky enough (sort of) for it to happen under warranty.

 

Bernard,

I think your saying the seat or valve seat when you mention sitting. It's the surface of the head the valve seals against.
