not burning as much oil as predicted

[sonyman87]

well i have been using mobil 1 for many thens of thousands of miles now and i have been going through about 7 quarts of oil between changes.

 

6quarts to fill after a 20 min drain. and 1 quart added at 2500 miles to make it to 3000.( = 7 quarts for those who cant count) oil still looks good at this time. i always figred i was burning the oil which is no biggin. highmilage motors do. well.. after washing the garage floor from doing a water pump i parked the car in there overnight for a few days and to my amazement there was damn clean oil on the ground. not a few drops but a small puddle. this is odd b/c it dosnt leak out at a fast rate and the motor dosnt have to be running for this to happen.. it just drips out! WTF! the oil plug isnt leaking. i dont think the new oil switch sensor is leaking. where else could this crap be leaking from when the car is off for long periods of time?

 

the oil pump 0-ring is dry. and the valley plate was cleaned and resealed when i resealed the 0-ring.

 

ohh the oil is in a general locatoin between the oilpan and where the oil filter is.. but there is so much deposit from oilchanges its hard to tell.

ideas???

So, you really aren't burning oil? How many miles are on your car now?

The 3.4's suck oil down between changes it's something with the PCV system.

 

About the oil leak, mine leaks there too, probably rear main or oil pan.

 

Get some of that blacklight finder shit.

I dont have a PVC system. got rid of that a while ago. so im not sucking oil in the intake.

How'd you do that?

 

Then you probably have a leak somewhere.

look at the front cam cover on the far left side

now look at the same valve cover with a breather installed.

i basicly ripped out both vacume lines and sealed off the intake with a new pipe. i put breathers on both front and rear valve covers.

 

also a note. the spash plate on the rear valve cover was swinging freely with 1 of the 2 hold down points attached.

i fixed that by repressing the loose down point and resecuring the exisitng one.

My Lumina leaks a few drops here and there nothing major, but don't all 3.4's leak a little bit? When my mom bought the Lumina it was put on an oil test thing the GM dealerships do to make sure there's nothing wrong.

idealy there shouldnt be any oil loss via leak.. its been doing this for a while b/c my favorit parking place at work is showing the same oil spots as my driveway. considering the just paved it in april there really hasnt been any other car there except mine.

And it doesn't put any excess oil in the engine bay? I would do that except since the 3.4 uses so much oil through the PCV, I want to make a catch can and have it go back to the oil pan.

No, but believe me, you have to clean that filter at least every month or so.

mine still look damn clean for what they are. like i said before there are splash guards on those things so it dosnt loose any oil out of them. never been an issue befor.

You sure your not loosing oil through those?

 

I would try to set up some kind of catch can for the PCV system.

if i was then it would be one hell of a trick.. oil defying gravity.. . last i looked it was coming toward the front. so the front valve cover should have oil pool over the t-belt cover but it dosnt. well. all i can say is nope not there. i will have to powerwash under the car and go from there i guess.

[digitaloutsider]

I'm very sure I'm not losing oil out of mine. Like I said, it gets full of it and you have to clean it, but that's the only problem I've had.
