hello everybody....

i have some bluish smoke coming out of my exhaust, but no oil in the charge pipes yet...

i have a fasturbo oil lines kit..

how can i know if i need a restrictor? and which one do i need?

thanks...

 

I've got smoke comming from the turbo. Noticed there is a small oil leak. Therefore I assumed I needed a restrictor, or new seals

i have no smoke from the turbo itself. only from the tailpipe....

 

Rings or hg. What color smoke?

To know if you need an oil restrictor you first need to know what oil pres your engine usually runs @, the you need to know the turbo manufacturers recomended oil supply pressure.

[QUOTE]

kinda blue

 

Only in boost? idle? decel? That can help us out too

 

Idle, accel, all that would point to the extent of the damage. Sounds like rings.

Blue-ish = rings/ring lands (your burnin oil)

Whit-ish = hg (your burnin water)

Im no pro but that's what it sounds like.

yes there is smoke at idle... and at boost too... i dont know what
decel is...sorry.


i'm going now to the gas station to buy some oil and a oil filter,
(i forgot that i didnt changed oils about 5 months (the car was standing))

what about my pcv system... could that cause the problam? (i will post an illustration in a few minutes)

thanks fellas

i got castrol GTX 20-50. and a new filter.

i'm gonna change it now and tell you guys what happend.

 

decel=deceleration(slowin down)

if its on decel, it usually is in the valvetrain, like worn valveguides or seals

 

it could still be the seals on the exhaust side of the turbo....am i right?

 

Your pcv system could be the cause, does smoke come out your valve cover breather?

your illustration is weird. Is this a bseries? You have 2 lines coming from the pcv box, one goes to a vent hole on the top of your block, the other goes to a one-way pcv valve, and then to the intake manifold.

You seem to have removed the line from the block and put it to a one way valve that goes to the atmosphere? What was your thinking that when the pcv closed in boost the one way would open based on crankcase pressure allowing crankcase ventilation?

why does it say "pneumatic filter (closed)" in your diagram?

blue smoke could also be the headgasket.


headgasket is a cheap fix compared to ringalnds

^^^
its the same valve that i had on the box. i just took a line from there to this filter and returned it back to the manifold. (where the line was)

yeah... i know...

ill do a compression/leakage check...

as far as i know if i have a oil leak to one of the chambers it will be hard to read it using a compression check... correct?


i changed the oil and its the same....(mabey less blue)

Do a comp test, leakdown test, and maybe a wet comp test. If it's an engine thing, then most likely the heads commin off and he'll be able to tell from that.

But as was stated before it might just be your turbo seals. The comp test(s) will give you needed info. Process of elimination. Do some tests and come back and let us know.

the thing is there is no oil in the charge pipes... and also the turbo isnt spitting oil while its revs up. (i unhooked the charge pipe and revd it)

 

That just means that the seals on the comp side r good, they may be bad on the turbine side. You can take your dp off and check out the outlet of your turbine housing.

yeah ill do it tommorow.

 

IM having the same problem at the moment. Seems like when i get on it hard it smokes. but if im light with acceleration it goes away. So i imagine i have a blown turbo seal. Its just not leaking at low pressure. Im gonna do a comp test and leakdown test tomorrow followed by taking off my downpipe. keep u guys posted. p.s im not running boost at the moment. Just built ls vtec with 8.5 1 standard srp pistons, eagle rods,acl bearings.54 miles on motor

ok. i removed the downpipe and i found oil in there....

could it be oil from the engine going through the turbo? and not from the turbo seals?

say that it is the turbo... how can i know what was the problam?

 

Check your return line

is it kinked?

 

no

like from the manifold to the turbo?

 

Ok so lastnight i put in my oil restrictor with an 063 thousanths hole. I ran that from the sandwich plate for greddy because there wasnt enought clearance on the turbo. I seems like it smokes alot less now but still smoking when v tec engauges. im runnin a stock ecu and injectors with the charge pipe off to break in the motor. a/f maps have been check and deemed safe for breakin
