First off I hate my luck!!!!!!!!!

Ok next... I am sure guys remember my build problems but just in case...I was burning oil like crazy (1 quart every 300miles) so I did a comp check and got 225 across the board...then a leakdown and got a 2% leakdown across the board. Ok so far so good.

So I pull the head and found that the head I bought had bad valve guides. Ok so now I think I have solved the problem, BUT (god I hate that word) After 400 dollars of machine shop work to fix the bad valve guides and the 2 bent valves in the head that was suposed to be in good shape I have no difference in oil burning.

I put the head on today and worked a couple little bugs and then drove it around. I have absolulty no change in the oil smoke coming out of the exhaust. I am still burning off oil like its fuel.

Ok so my leakdown and compression check are good...my head is basically brand new now and still burning oil.

WHAT ELSE COULD MAKE AN ENGINE BURN TONS OF OIL!!!!!!!!?????????

My mechanic suggests that it could be bad ringlands, but I just dont see that being the problem with JE forged pistons and iron sleeves and the low amount of miles on it.

So what do you guys think? Oh yeah and all that stuff in my sig is just extra... I havnt pulled it apart yet!

 

did you buy all brand new valve guide seals, for all the valve guides?

 

Yes brand new valves, valve guides and valve seals and a pull machine shop inspection and hot tank. I am telling you I thought the headwas abrand new onw when I got it back (except for the crower springs and retainers )

 

Remember what I was saying about the synthetic oil being used during breakin........

Naw, it very well may end up being that. You've got the valve guides, valve seals, valves, and valve seats all taken care of and checked. That only leaves the rings/cylinder walls.

EDIT - FYI, I got my H23 VTEC running today! Finally! I can't wait to get the axles back in and get insurance on it! We gotta meet up when your problems get taken care of!

 

Ok se heres the thing... while the head was off I took a look at each and every cylinder wall very carfully and they are imaculate!

I also got all 4 cylinders even and poored some cheep *** oil on top of the pistons to see if it would leak down into the block and I had to suck it out 15 minutes later because it wouldnt go past the rings.

I really need a miracle cure here!

 

so noone has any ideas? At least tell me that you have never seen this before

 

i have never seen this before!!!!!! lol. so is this an h23 vtec or is this a h22? what are your mods. ALSO, have you been tuned, that sort of ****. you have gone through alot of touble and im supprize you havent found out wtf it is. Not leaving oil on the ground or anything, just burning it all ? shooting nice size black louds?

 

i would suggest you doing a new compression test and leak down test atleast thats a place to start.

im wondering if your mechanic is very compitent. do it your self. oil can only come from so many places. either its getting sucked in through the intake manifold some how. it getting past the rings, or you still have head problems.

if you do anther compression test and leak donw test and the numbers come out good then i would say the head still isn't right

 

Maybe PCV valve?

 

pcv valve tested good.

I havnt tuned it yet because it runs like *** and I am not gonna waste money. Its blowing nothin but blue smoke.

My mechanic realls only gives me advice. I do all the work myself. When I pulled the head the intake manifold was clean!

I am lost... any one want to buy a motor!?

I am just gonna buy a jdm motor and call it a day, sell the lude and go to the dark world of the b series!

NOOOOOOOOOOOOOOO...!!
[/slow motion voice]

don't quit that easy. im telling you do another compression check and leak down test.

how bad is it blowing oil? are you sure its not just burning off residual oil? run for a while the way it is and pull all the plugs, and see which one or if any you see oil on,

Let me put it to you this way. I got pissed off today because it is smoking so I slamed on the gas pedal and ran it up to 6000 rpms! (Man I was pissed) I was suprised to see that it pulled like a som of a bitch but when I looked in my rearview I couldnt even tell there was a car behind me till the smoke cleared.

NOTHING BUT BLUE! I give up, I am done, I cant keep borrowing peoples cars. I need something else. **** H SERIES MOTORS AND MY ITALIAN ATTITUDE!

 

ok ill buy the bottom end. its sleved . hehe

seriously, run it for a while and look at the plugs, and do another leak down and compression check.

or for ***** and gigles swap a different head on there , i mean youve got to be a pro at this by now

 

Is your intake full of oil?

Read the post

I really dont want to change the head again! But its an idea.

 

aww comon, we know everyone loves to shoot big fat *** clouds!

That is really weird. Any chance the breather from the head is putting oil into your intake and its burning it off ? no sludge in the intake manny when you pulled it? or did you notice the smoke and pull the head right away or been running it for awhile?

 

I have a mysterious dissappearing oil issue too. No blue smoke, but starting at 5k i spit out huge clouds of black smoke.. yet my air/fuel ratio is dead nuts perfect.... I lose a quart every 500-800 miles.

 

i bet it's the rings... either that or the machine guy fucked up..

 

i dont know too much but could a ring or two be collapsing under load? or at a certain rpm thats letting the oil passs by, something that wouldnt happen while checking for compression??

 

That whatI am thinking. I thin that when the motor is not running it does fine with holdiong oil but as soonas those rings are in motion they are just fubar! Either that or it is the ringland like my mechanic says.

Anyway I dont know what the hell to do

No sludge manifold was CLEAN!!!!!
And I pulled the tube that goes to the intake just incase and put in one of those gay ricer breathers....and no difference what a suprise!

 

This might be worth a try:

Remove the PCV valve completely, jam a length of hose into the breather hole, and run the hose down to the underneath of the car. Now take a run in the car and see if the blue smoke disappears.

How did you test the PCV valve? Too much crankcase pressure will push up oil from the crankcase, past the rings when the piston is in its "induction" stroke.

Check for oil being blasted out the hose when driving too as this might indicate that you have too much oil pressure for some reason.

This is worth a try since you seem to have tried everything else!

 

not a bad idea. I tested the pvc valve by thehelms to make sure it worked. All you gotta dois squeezerthehose and listen for aclick in the valve. I might have to find a hose and try it

But that stillbrings me tothe fact that my intakle manifold was clean as new!

 

The PCV valve can go faulty in two ways:

A faulty PCV valve can cause the inlet manifold vacuum to "suck" oil from the crankcase when engine inlet manifold vacuum is high. A prime example of this is a smoky exhaust as the car is decelerating under engine breaking The telltale for this is oil in your intake manifold but remember that Hondas seem to suffer from oil surge under heavy cornering and high engineload anyway, which will "push" oil past a fully operational PCV valve, hence the messy intake manifold.

Your PCV valve may not be allowing the crankcase to breathe sufficiently which will cause oil to be drawn up past the rings on the piston "induction" stroke. High compression pistons can cause a greater amount of blow-by gases and hence a greater crankcase pressure anyway

Do what I have done and run an "open loop" system by runnning a length of hose (without PCV) to an oil catch can and then vent what is left out underneath the car.
A moving car will create a negative pressure below the hose mouth which will help draw gasses out as well.

Cars ran this way for many years before the environmentalists got wind of it, oops.

 

so what kind/ size hose should I try? At this point I will try anything!

i'm thinking it's the rinlands too.
just out of curiosity, what was your technique of breaking
in the motor?
