[Mr_GaZZa]

Hey every1,

more on tick over or crawling... and on standstill when u give it a REV...

its never done it b4

got my car boosted 'with manual controller' and dyno'd @ streetforce... i said i only wanted 10PSI

but the bugger tired for more when i got cash out!!! n said that didnt make much more power @ 14psi

i mean then he turned it down to 10ish!!

DAM!! what is gone? how can i look for wat it is? would i be valves guides? turbo? piston rings?

i am so angry now at him for that!!

HELP ME PLZ

i woudnt think 1 run at 14 psi would hurt the engine unless it was badly tuned

undo some of your cooler pipework and look for oil in the pipes

if you see a bit, wipe it away then run the car again

if it comes back quickly then youve probably shagged the turbo oil seal

or it could be leaking on the exhaust side, which is whats making it smoke, as you have raw oil leaking into the exhaust housing

yeah i took one pipe of b4 it goes into the intercooler... looked coated in oilly stuff so gave it a clean.. going to install n start up again!

if its the rear , just remove the frontpipe n look?

if your referring to the exhaust side youll need to drop the exhaust off at the dump pipe / front pipe area and look from there

its natural for some trace amounts of oil to be there (visual) but it shouldnt be dripping / fresh

okay working on that bit now!!

um... what / where can i find my PCV ... heard other ppl mention that with this issue... maybe mine needed a replacement.. awhile bk i had idle problems n kinda fixed it self

with lil adjustments to the idle screw!!!

also only other problem i had was WRX sound randomly... but only in winter /dampness ... once a week at most... maybe they where signs =(

hasnt done that for 2months but

omg

[DRIFTER]

sounds like broken pistons.

[Mr_GaZZa]

sounds like broken pistons.

NO NO!!! aint lost no performance, no heat gains, no real oil usage or any WIERD noises

i thinks its the rear turbo seals

=(

any1 else got any ideas??

BTW cars nearrly done 160 ### km

PCV = positive crankcase ventillation..... and where u find it im not sure...i havent had a look on my car, haha... but it is usually on the top of your tappet cover, with a pipe running from it back into your intake.

[Simon-S14]

its on the intake plenum where the engine breather hose goes in

[DRIFTER]

didn't realize you came on these forums simon. nathan weissel

[Mr_GaZZa]

hey all

been working / finding out stuff all day about my car!!

only smokes when hot, and only after its sitting ther n u give it a rev u get a lil puff...

it doesnt smoke when or acceleration or de/ acceleration and doesnt smoke when cold!

performance is same, oil pressure remains to its normal pressures i see and engines temps are well under half way !!!

me thinks it REAR turbine oil seal =(

LF new turbo / or place in Perth to rebuild it....

P.S thanks every1 for ur input

If possible,

do a compression test on all cylinders

post up the results !

[Sambo33]

sounds like pistons to me, i had this problem too, same colour smoke ect. still had good performance, but blowing heaps of smoke and using up my oil. took it to my tuner he tells me its pistons.. pulled the engine to bits and all 6 ringlands were f**ked

sorry, probably not what u want to hear, but before you get the turbo rebuilt get a leak down/compression test done

[Taxi33]

Same thing with me.

If their is oil in your piping,

compression test straight away!

Good luck!

[mjones]

it could also be ur valve stem seals

[Taxi33]

Yeah, there is a way too find out which one it is

while doing a compression test.

I'm not too sure how to do it!

But i think it's were you put oil on top of the cylinder

and then when you do the compression test,

if it goes higher its your stem seals or if it stays the same

it's your rings.

Not too sure though so if someone could correct that will be good.

[Mr_GaZZa]

noooooooooooooooooooooooooo!!!!!!!!

RAWR

i hope its just something cheap/ easy to fix

omg BS >< if it was pistons wuldnt u be burning oil.. n wuldnt it be worse @ cold start :S

and i dont get no smoke while cruising... n stuff all or if any when pulling away **looks in mirrors**

also took off oil cap, no signs of back pressuse or spitting, just a slit change in idle...

=(

thanks guys.... i'll keep my options open, until i go to a few yards n mates @ tuning shops / nissan n see wat they

say 2

thanks

BTW compression test will be done this w/e coming

Yeah, with my one there was no smoke or anything blowing out

while driving or anything like that, just sometimes blue smoke on idle!

Check your dipstick after you for a drive and see what it reads hehe

[SSN8R]

thats right.. if u put in oil and do the compression test it should help verify wether its valve guides, stem seals etc

just becareful wat shops u go man same thing used to happen in my other car, not a nissan but under load/boost it used to puff a blue smoke.. and sometimes on vaccum once cruising car slowing itself down from 80,60 it used to blow alot of blue

went to tonnes of workshops they said needs a rebuild, some said rings r going, some said valve stem seals or valve guides..compression tests came up fine. opened it up myself it was only a manifold gasket cracked,

even when i used to rev it at neutral up to 3 grand for 10 seconds then backoff it started to blow the blue.

sometimes its not as bad as it sounds.. get compression test first, start ur way from the bottom and go up
