4Qts in 2000 miles.

[Dominasian]

When i bought my car, i did an oil change right away just to forget about some simple maintenance. The car used to leak from bottom and valve cover. We changed a valve cover after about 1000 miles driven, it stopped leaking from top.
Now, i believe i have a leak from an oil pan ( i have oil everywhere underneath, and oil pan is always wet ) with that said i just checked the oil level after 2000 miles driven and i had almost no oil...

Does my car eats oil like crazy or it leaks like crazy ?
Yes oil does leak but i don't see any oil stains on the floor from over night, maybe because its too cold in here. but i usually always smell oil after i make couple of hard launches...

After changing to a new valve cover, i put a new valve cover gasket along with 4 plug gaskets and half moon seal. It doesn't look like valve cover is leaking, but i can surely tell its soaking a little. Once i noticed that after a hard run, i heard a boiling noise from a valve cover. Unscrewed the plug cover and noticed that my 4th plus is making this boiling noise, when popped the plug wire i saw no signs of oil in the spark plug area, so why would it make that boiling noise ?

When i opened the spark plug cover, i noticed an amount of oil collected in the valve cover area. This happened before with cracked valve cover, but now i don't know when and how it gets collected there

Does the car smoke at all? If its burning that much, you'd def notice some smoke.

If not, then I would assume you have a good leak that needs to be address'd ASAP.

How hard is it to fix an oil pan leaks ?
Unscrew, put new gasket and screw back in ?

Does my exhaust leak at the catalytic has something do to with oil running away ?

Check the PCV system, if it is not right you could be pressurizing the engine and pushing oil out on your hard launches and pulls.

This may also explain why you are not getting oil puddles under the car when left over night.

We did a pressure down test when we changed the valve cover and everything was right, so the guy who did it couldn't figure out why it was running oil from top on the valve cover.

Also PCV was checked too, and it was clogged when we took it out, but cleaned when we put it back in.

Dang, half a quart left in the pan ... has your oil light been coming on any? If so, I can see scorched cylinder walls and crank bearings scorching the crank which spells death to a motor and this will eat oil like mad until overhaul.

Valve seals are gone - check your plugs: if they are clean, then valve seals. If black and wet, then a ring issue.

The PCV issue is a big one as well that will eat oil like mad if the above two issues comes up negative.

But, A gallon of oil (500miles per quart spells problems right there) in 2k miles can spell a tired motor with a lot of miles on it esp if it hasn't been overhauled

are you shure you dont have any blue smoke at all, maybe while your doing a hard pull. turbo oil seals are pretty common. when mine was bad i added oil very often.

Check your oil filter housing too. Previous owner on my car had an aftermarket oil gauge and it leaked bad when the car was running. It sprayed all over the oil pan so it took me forever to figure out where it was actually coming from. And try replacing the PCV valve. From what I've heard, they are known to go bad. They are cheap enough to buy just to rule out in any case.
If I were you, I wouldn't do any pulls or hard driving until you figure out where it's leaking or burning.

Just to help clear things up a little, I was the one who helped the OP with all the work mentioned. We didn't get around to the cylinder leak-down testing, but we did perform a compression test with good results. IIRC, the engine had around 150-160psi across the board. Also, the replacement valve cover didn't include a PCV so we used the old one. After some testing and cleaning of course. It was seriously gummed up which made it leak pretty bad, but after a few shots of carb cleaner it worked flawlessly. So I was pretty confident that CC pressure would be seriously reduced.

However, the OP is also using an inline filter between the breather port and intake. It's a much larger unit than the clear filters that are commonly used, but still a considerable restriction. Especially if it hasn't been replaced since the PCV operation was restored.

The oil leak is also what I would consider pretty serious. It's not the light film of oil you get from a small leak at the turbo drain or cam seal. We're talking about the entire timing side of the engine bay being saturated with fresh oil and greasy buildup. The car really doesn't leave much oil on the ground either, which makes me think the leak is only serious at high pressure.

Bad gasket, warped cover, or similar?

Hit the car wash and power spray all the gunk off where one can follow the leak better.

If memory serves me all you need to do is drop your Exhaust down pipe, then your Transfer Case. After that you should be albe to drop your pan and change the gasket.

 

[Dominasian]

Wes, timing side has stopped leaking from the top after we changed the valve cover, its just a bottom-drivers side of the engine that is in oil, and with my understanding its pretty much oil pan, its the lowest point of the engine bay pretty much and when i drive the car, all that oil gets on catalytic and smells like burning oil.

 

[Insane20]

possibly the oil cooler o-ring, or the front crank seal behind the crank pully. that would make sence.

 

[DSM1G90]

Can agree on front main seal - got blown out due to excessive crankcase pressure...or, the teflon got rock hard and began to cut a minute ring around the crank end where no seal will ever cure a leak there.

 

[knochgoon24]

When I had a front mail seal go, it slung so much oil out that it when parked, it would drip and leave a foot diameter puddle. Even then, it wouldn't go through more than a quart a week.

Does it have a BSE? Maybe the plug installed for the front shaft is leaking...

 

[squeak104]

With a converter on it you wont notice the oil being burned as much. When I had my other turbo on the car would use a quart every week and a half but I wouldn't see any smoke. Newer turbo on and no more using oil. Any oil in intake pipe or post turbo in the piping?

 

[Diamond Star Werks]

I go through oil like this too and idk where it goes. I went through like a quart+ in a 500 mile drive no boost. Car does not smoke either unless wot. and only when boost first comes in. or in really cold weather. Warm weather didn't smoke a bit. No leaks at all either.
Dude I hope you figure it out, maybe this can help me too.

 

[DSM1G90]

Maybe tired oil rings and/or valve guides/seals have issues to let oil slide by and be burnt off ... gradually. What does your plugs looks like - clean and white, or dark to almost sooty. Poke your finger in the exhaust pipe and give it a wipe. See what comes out - soot or slime.

PCV system checks out?

You do WOT, then close the throttle which creates tons of vacuum which can pull oil past the rings to be burnt off.
