oil vanishes

[cborden]

i wanted to know what you guys/girls thought about this
my db8 has about 177000 on it
but ive replaced valve stem seals
piston rings
head gasket
oil pan gasket
vtec gasket
camseals
valve cover gasket
but after i do an oil change about two days after all the oil is gone

Wow

 

[cborden]

you see what i mean

 

[Cman46290]

Have you looked all over under the car for leaks? And under the hood an stuff? Thats CANT be just vanishing into thin air... its gotte be going somewhere....

Hopefully not a head gasket... or piston rings....

What all have you checked?

 

[cborden]

yup ive looked under car while its runnin it seems to be vanishing while im drivin so when it pressurizes it must find a leak
and ive already changed head gasket and piston rings

any smoke, in the low or high rpms?

 

[Cman46290]

Wow... thats ALOT of oil to be burning up in the engine...

you see any smoke out of the exhaust... or anything unusual about how the car drives? im kinda stumped ATM

 

[cborden]

nope no smoke ive noticed
its actually been actin better than before
a/f ratio used to be way messed up and left black trail on bumper but now thats fixed but still losin oil somehow
and it drives normal still gets up pretty good
but every so often now i get a little stutter or hesitation around 3-4k

 

[tsu878]

did you check the piston to wall clearances when the work was done?

 

[cborden]

sure didnt had it done
but would that really make the oil disappear that quickly
especially since i aint gettin no smoke

 

[tsu878]

if you have that black stuff on your bumper its burning oi.l the ring gap could be to big. i would get oversized pistons (81.5mm), get it bored and honed. if you like all motor look into Civic type R piston for high cp. if you plan on turbo later go integra LS pistons, they are lower cp. forged is up to you.

 

[cborden]

honestly i just need it to hold up for a few more months
then im gettin my itr
plus im not gettin black on bumper anymore

 

[tsu878]

cool, just keep an eye on the oil levels.

So you had the motor worked on by a shop.

Were the cylinder walls honed/bored over?

Was the block decked, cylinder head resurfaced?

What brand were the piston rings, valve seals, and headgasket?

Were the valve guides replaced in the head?

Is your motor clean, with no apparent leaks?
-maybe its running down your block from the VC in the back, and you cant see it
-It may also be leaking from the cam seals under the timing belt cover, running down, then dripping onto the header/burning off. This is what mine does.
