hello guys...
i have a b16a2 engine with
-cp pistons 81,5
-eagle rods
-supertech dual springs and ti retainers
-GT3071R garrett turbo


the clearness on the rods are .40-.40-.43-.45 and the clearness on the pistons is the recomended into the cp manual. i dont remember that.

when i went a travel the car didnt burns oil..absolutly full of oil into the engine.

BUT when i kick my cars *** at 15 psi the car needs 100 ml / 500 km
this is normal??

everything in my car is new....pistons springs,etc etc....and the turbo is new with 0.35 restrictor...
but when i unistall a charge pipe for a check i see oil in the corners of the charge pipe. 4-5 litle drops of oil after the car was 10 hours off...absolutly cold.

another strange thing is that the oil presure gauge reads 100 psi presure at 3000 rpm and keep it stable at 4-5-6-7-8-9 thousands rpm...
is this too high??? is this normal?

Sorry for my English..this isnt my basic language

rev-speed

how big is the drian

habib

What size is your feed line

Nick_p

the oil feed is 4N with .035" oil restrictor
and the drian is 10N .

the drian isnt instantly on the oil pan..
goes under the turbo and then goes a litle upper and finally goes
in the upper point of the oil pan...



what about my oil pressure? 100 psi is normal?

That's the problem there. It needs to be a -8AN with a direct slope down to the oil pan. It cannot "go up a little" at all....

Change that drain configuration.. problem will be solved.

TiAL

no, 10AN is better than 8

It cannot "go up a little" at all....

SLIM NOTHING

dude just listen to TheShodan i have never seen him steer anyone wrong.. if you want it fixed take that answer and go do it now. problem solved.

Nick_p

yes...i think this is the right thing..

the strange thing is that sometimes i see in the mirror back and i see a cloud of white smoke.
i see that when i am at idle...and the car move a litle...i think.
i accelerate a litle and the cloud disapeared..i go to check it and there is no oil go out from exhaust.
i accelerate about 5500 and i go to check and there is no oil again...
WTF is this cloud sometimes.....
the sparks is dry....no oil....
so i think the turbo leaks to exhaust.
why some times this makes cloud and all the others times is normal ??
dam...my head...
the only thing i am happy is that on the dyno the car is too strong..

Tony the Tiger

I think Shodan meant that the drain line has to be at least-8AN

TheShodan

iTrader: (14)

Thanks Tony.. yes. at least 8AN


Haven't you had your Joose for the day, TiAL? I know you have one stashed in your office somewhere as a spare. ;-)

Nick_p

ok. i already uninstall the turbo to fix the drain..

the drain was completely wrong.

BUT i saw into the pipes A LOT OF oil....
there is a problem with the turbo? how can i check it? or everything was from the fault drain??
the entire setup has 3000 km,engine,turbo...everythin..and 1 hour of dyno.

Shodan...please help..
anyone??

TheShodan

Drain only. once you get that right, clean out your IC pipes with brake cleaner. Oil drain can create a lot of problems its not hook up correctly in a pressurized system.

Nick_p

guys i fixed the drain..... now the car smokes (white) all the time....
whats going on??

we talk about a cloud smoke all the time...ALL the time...!

i am very sad for that...seems like turbo leaks into the exhaust...

any ideas?

what else?? my engine have cp pistons 81,5 and i give the clearness in the info in the cp box.

the only thing i can think about is the blockguard.... i install it after the hone job. but everything seems good and center.

Nick_p

i unistall the external wastegate.
the car smokes from the exhaust back of the car like oil factory...
BUT from the external the gas is clear....

So....the gas from my engine is clear...but the gas when go to the turbo and then to the exhaust smokes...

So turbo is off......right??

the car smokes at idle and ati high rpm....
i have 25 psi oil presure at idle and about 100 psi at full rpm oil presure.
i have a .035 oil restrictor to my turbo.
this presure is good?? or is too high??

another question.....can i replace my turbo with GT35 but with my compresor house and my turbine house?
my turbo is GT3071R with 50 AR compresor house and .64 turbine house.

Give it some time to burn out all the oil leftover in your exhaust..
I would run a -3an feed with the restrictor... What kind of oil are you running? Try some 10w30

I had a brand new gt37 fail from day.. Smoked from day 1 at idle and wot and ate up .5qt of oil every 1000 miles... Bluish smoke and you can see oil in your exhaust tip...

Nick_p

i would run -4an feed with .035" oil restrictor.
i running ENEOS 10w40

the strange thing is that before i fixed the drain the car smokes sometimes...and not every time..
now i fixed the drain and i change the oil with new ENEOS 10w40 but the car smokes everytime....i unistal the external and is clear.. but the exhaust smokes...

and i find again oil in the intake pipe close to the turbo..

Nick_p

another guy tell me that my oil presure is high even if i use .035" oil restrictor..

the oil presure gauge says that at idle i have 20-25 psi and ai high rpm i have 100 psi....

the .035" oil restrictor i already use is ok for that presure?

TheShodan

Ok. You need to check to see if you're having some other problems associated with the engine itself. (White smoke is more likely coolant, not oil). So do a compression and leakdown test to make sure you haven't messed something else up.

Second, use a -3AN to a .035" restrictor. Although from a technical standpoint you should be ok, using a -3AN is the proper size for a honda with that drain. Check that drain again to make sure there are no 90 degree angled AN fittings on the return line. That will cause a huge oil back up.

third, NO. A GT35 will NOT fit any of the housings that you have, nor would you want something of that size internally gated and restricted like that. I would never do that even if it was possible as a custom (and thereby very expensive turbocharger).

If you're running the proper restrictor, you should be fine, this means you have to look at that drain configuration again, if it is indeed oil back up. check that, and make sure all that oil burned oil is out of your exhaust system.

After that, there's not much more to be done.

have a nice day

ashb82

can you post a pic of the drain

Nick_p

Ok the gas when went out from the exhaust manifold is clear. This mean that the engine is perfect.
The only thing i thing about is that i have a litle white presure out from the top valve cover port out to the oil catch. Only this.

My drain is exactly down the turbo into the block.
The line as i said is 4n with .035" oil restrictor.
My oil presure is 25 psi at idle and the highest is 100 psi.


My friend explain me more about that.
I use the oem black box back from the block and the hose that goes to pvc valve and then to intake maniflod i remove it from the intake manifold and put it direct to the oil catch without the pcv valve.


Here some pictures.

Oil starts from turbo direct down



The the hose is about 4" and goes direct into the left side ... there is no oil... This is the reason i choose this point. And the oil grom turbo have a lot of room to goes down.

Nick_p

TheShodan my friend i already use the water cooling method to the turbo but i think is oil leak from the turbo because i found some oil in the pre-intake pipe... Think about this....
Much more oil in the intercooler... And in the exhaust for sure....

So... ?

Normally it does take some time to burn off residual oils left behind, but if it's still smoking and worse than before then you definitely have an issue.

Try this. Take the turbo back off, pull both the compressor and turbine housing off and clean them thoroughly with brake cleaner. Oil will pool in these housings and could be causing your current issue. Do this and reinstall the turbo. Remove te intercooler piping and clean it as well. Remove the intercooler and drain/clean it.

Reinstall everything and try again. If it smokes for more than 5-10 minutes the turbo is shot. I don't believe Garrett will warranty the center section due to installer error. Expect a new center section to be in the area of 850 US dollars, iirc.

hello again...

i just returned from the shop i was bought the turbo.

when i pull up the oil pointer air comes out...this means that i have completely wrong presure out system ( how you say this in America? sorry)
and when we have presure there the presure dont let the oil from the drain cames out..

the smoke from the exhaust now is less....

he said to me that the drain is too short and the turbo to low and maybe i need a top mount exhaust manifold ....
