oil leves are fine.
No consumption of oil..
When I checked out oil levels. the car wasnt on level grounds =P dum me!

No smoking on start up now that the weather is getting warmer.
The white smoke occasionally on start up and while driving for a bit was just condensation in the exhaust pipes

kyden

you see any smoke coming out of the back?

wtsapexipowerfc

none
only on cold start up

How is crankcase breathing setup?

i had this same exact issue on my old turbo DA. except i saw smoke.

was running an sc6152e and for the life of me couldnt fix this issue..ran open pcv/stock pcv/big catch can... nothing ever fixed it.


cruising around 40mph at like 3,000-3,500rpm then let off it would put out clouds of smoke.

in full boost and higher rpm cruising i had no issue...only thing i never tried was an oil restricter because i could never get one to work with my feed line.

i have 3 lines from valve cover into a closed catch can, and I have one big hose from bottom of catch can to intake arm which is attached to turbo..

wtsapexipowerfc

There was a ton of smoke before i put the oil restrictor on?.. could the turbo seal be bad?? and the oil restrictor is just a bandaid fix?

wtsapexipowerfc

there was a ton of smoke before the restrictor was put in.. smoke passing through the seals

wtsapexipowerfc

i just checked it again right now
and its just under the top dot
didnt start it or anything

but before checking it this morning i had to move my car quick so my parents could get out of the driveway
anyways
car ran for like 5 minutes
put it in garage
and turned it off
checked it and it was under half
lol
is this normal?

nemisish20

Is the catch can filling up and not venting back into the engine?

The turbo seal could be bad.

Maybe one or several of the oil galleys is clogged and the oil is staying in the head for longer than normal.

There are so many different ways to track down an oiling issue.

If you have any issues click my link and give me a call i can help with any oiling issues you may have. Or PM me.

Why do you have a hose going from the catch can to the intake?

nemisish20

After reading the thread over again i asked my self the SAME question. The bottom line from a catch can is usually the drain/petcock.

Why would you want the oil drain line from the catch can going directly into the intake or turbo intake?

That may be your problem right there.

darkvader0

Think this is most likely your cuplrit right here. If you had a smoking turbo and then just installed oil restrictor without addressing the turbo oil seals, you just band-aided it.

And yeah like others said I would rethink the line from your catch can to the intake. Probably a better idea to cap it off and let it full up. At least until finish diagnosing.

Glove

no, its his catch-can setup,

wtf, all his oil getting drained into the catchcan is getting sucked back into his motor.

Who told you to have the catchcan setup this way? its retarded.

I would start with that, plug the bottom of the catchcan or re-route it back to the block, and make a vent at the top of the can,

start with that

nemisish20

The purpose of a catch can is to catch the excess oil vapors from the high crank pressures in the engine and then once the pressure equalizes the oil in the can usually gets pushed back into the engine.

Most companies (mine included) put petcocks on the bottom of the catch can so that you could drain it after a hard racing session or hard street driving.

You stated be fore that when you didnt have a restrictor, the car smoked. You put a restrictor on and it doesnt smoke anymore but the oil is still disappearing? .. You also mention that you have a line from the bottom of the catch tank into the turbo inlet/intake pipe.

You answered all of your own questions.

Plug the catch can, rebuild/replace the turbo, and make sure to research new products and read the instructions.

If you have any questions like i said just give me a pm and i can help you out.

wtsapexipowerfc

having a line from catch can to the intake "pre turbo" ascertains that there will be a bit of vacuum, thus further reducing crankcase pressure.

If i remove this line, then there will be more crank case pressure..

SL0WEGG

how do you figure? If you have the line at the bottom of the catchcan going to the intake side of the turbo. All of the oil you are catching is going right through your turbo back into your motor.

the crankcase should be one of two waus vented to tmosphere or connected to a vacuum source via the exjaust system not the intake system. your sucking oil and vapors back into the engine which reduces fuel octane and gums things up

That being said it should be smoking an aweful lot to be burning through that much oil. is the catch can full? have you done the cardboard test? put cardboard under the engine while its running see for leaks. i doubt its burning that much oil that quickly and not smoking, its impossible. what oil r u running?

wtsapexipowerfc

I am running 5w30 oil weight.
No oil on cardboard/newspaper under the car while running.
I think i just checked the oil wrong.. didnt let the oil drop to the pan before I checked it.

not weight of oil, what brand? convention or synthetic?

The only oils i know that will be consumed rapidly are royal purple which also causes leaks and mobile one

th3pwn3r

I think so too.

wtsapexipowerfc

I am using castrol syntec full synthetic

Turbo-LS

iTrader: (4)

Hmm castrol shouldnt burn up like that . Built or stock motor? any clue on ring gaps?

wtsapexipowerfc

built vitara motor.
the clearances are a bit loose side

Turbo-LS

iTrader: (4)

yesh those are a loose motor but still thats alot of oil. with sucha loose motor its best to have a peroperly designed catch can setup. that thing makes alot of crank pressure im sure and yrou pushing oil out
