I was at full line on Thursday, checked Sunday and down a quart already?!?!?!?!

My car is 98 civic lx chasis, with 95 zc block and 98 ex Vtec d16y8 head, with auto trans...

I have a skunk 2 intake manifold, cold air intake, headers with down pipe, then rest of exhaust pipe is stock lx pipe with muffler stock...

I did full tune up, (changed pcv also)... Did compression test on cylinders, readings were 225,223,215,230... Had head checked before mini me swap, vaccuum test were good on it, I set my timing to 18 degrees, spark plugs .044, using 10w30 oil...

One check engine light for secondary o2 not being hooked up(don't see that losing oil)

I notice that when Vtec pops alittle white cloud poofs out...

Anyone have any idea where my oils going?

I've replaced all oil leaks including main seals, entire block is clean

 

If there are no leaks?? Engine is burning oil.

 

Engine's burning oil then.

 

Def no visible leaks? check real good, dizzy, valve cover area, cam seal, vtec solenoid, then get under the car, check rear main seal etc.

If all that checks out it is prob rings.

 

Is your engine surface completely free of oil? You can leak a lot of oil while driving and not notice it.

 

Also maybe try cleaning up the engine bay and then looking for leaks. It will be more noticeable.

 

No visable leaks anywhere, I've already cleaned the block, one side note, what causes radiator hoses to collapse after motor turned off?

 

Old *** radiator hoses.

 

Do you WOT alot?

Yea I wot a lot, does white smoke some but only under wot

 

Well I can see I might have a head Gasket leak for the coolant going into the combustion cause of the white smoke but where's my oil going? Block cleaned, no leaks, no black smoke, not mixing with coolant, no power loss at all, car runs full power, compression test good, any idea guys?

 

Combustion chamber*

 

We told you. You are burning it. Do a leakdown test.

 

Explain leakdown test

 

Google. FAQs.

 

its gotta be burning oil if it has nooo leaks >___<

 

Exactly.

The reason I asked if you WOT alot is because you have VTEC. While VTEC is engaged, its common that you will burn some oil.

I'm do a compression test in your cylinders to test the head gasket, very easy and very simple

 

I think VTEC is your cause slightly though

 

sounds like your headgasket it shot, definitely change that out. i'd also do a compression test to see if the cylinders are all even

 

It's possible you're just burning the oil. But a white smoke sounds like a headgasket problem to me... Is there any oil dripping from under the car?

 

Alot of you guys need to read dudes 1st post. I say your burning it up. Maybe your valve seals are JUST starting to go so under wot it's burning da oil and your 215 compression on that cylinder should be your leak area for the coolant.

 

Stay off vtec for a few days and compare how much is burned off to before
