new turbo and its been on the car for about 6 months so far...

i'm using a -3 feed and a -10 return. car drives fine and pulls hard. no smoke when cruising, no smoke when getting on it at WOT, but after a hard pull or 2 or extend high rpm freeway driving, it smokes when i come to a stop.

it will be fine when i come to a stop for about 20 secs... then smoke would start coming out. its blue so its oil. itll come out for about 30 secs - 1 min depending how hard i drove it or how long its been revved high (3.5k-4k rpm)

but when i come to a stop and it starts coming out, i can take off and right when i take off theres nothing coming out.

only at idle...

my return line isnt that great though... i'm thinking thats it. it goes straight down for about 8 to 9 inches. then it goes pretty horizontal for about a foot. then theres a 90 deg fitting that goes into the top of the pan...

is this the problem?

if its bluish white smoke its not the oil, its coolant. burning oil tends to be black. check ur coolant levels and do a compression test if you can. might be a blown headgasket

head gasket huh.... but if its my head gasket wouldnt my cars oil and coolant be mixing... i just changed my oil and it looks fine... nothing in my coolant either

the smoke actually looks white sometimes... but its hard to tell whether its blue or white to me.... maybe ill record it with my phone today and post it up to see everyones opinions

i was leaning toward the oil line because i would see oil seeping out of my compressor... so i think its just getting backed up and comng out and burning

either that or im getting too much presure with a -3 line still

what are you using for a pcv setup? I ran the line of my head to my air intake tube of my turbo, so it was good, but i forgot about the back of the block. That one does have a pcv in it, so it shouldn't be boosting, however at the end of last year, i started having issues like that, after boosting for about two months. I had perfect compression, rebuilt a different motor this winter, planned, but tore down my other one, and it showed no signs of issues. I did however find that my pcv valve was not working anymore, could blow air both ways, so i'm thinking that i was boosting my crankcase, thus the smoke. Hence why i ask you

yeah my pcv was stock all the way around except for a breather on the valve cover for 4 out of the 6 months it was running. it was fine then it just started doing this...

then i hollowed out my pcv valve and ran it to a open can... (its a h22 so i dont have that thing in the back of the block) and i just did this about a month ago...

and its still doing this... its actually getting a bit worse i think, the smoking..

i ran 2 nsx's at the same time yesterday and when i left them far behind it was coming out alot when i came to a light... but stopped when the light turned green when i went

raceACCORDingly

so smoking on deceleration?

if thats the case i read that it could be your valve stem seals or the turbo seals. are you running a restrictor on the oil feed?

get a leak down test done to see if its turbo or motor.

i bet your oil is backing up in your drain. same exact thing happened to me on my d16z6 with a 14b. I put on a feed restrictor and a better drain and it worked great.

what turbo is it?

definately blown turbo seals

booja

its a gt35e turbo...

i wasnt sure on whether to use a restrictor on a -3 line... thought it should be fine...

no smoke on decel or accel, just idle. and when i rev at a stop while its smoking itll stop.

ive blown out a turbo b4 and it smoked while i was driving and i saw oil coming and leaking from the center section. but on this i only see oil seeping out the compressor inlet... not alot, very little. ive heard its normal

im not sire what it is.. im going to get it to st00pid on tuesday to see what he says about it.

im also considering a restrictor. if the restrictor is a .065 wouldnt that make the pressure the same no matter if its on a -4 line or -3... its the same size hole... i dont think it cam make even less pressure on a -3 with it... hole is still the same size... .065

I had a similar problem. https://honda-tech.com/zerothread?id=1544369

im not 100% on this but doesnt that turbo REQUIRE an oil restrictor.

hmmm i hope not ive been runnin it for 6 months like this...

i know the BB gt35r's have one built in and they are not able to see high pressure... but im not sure if thats with the r's only or gt turbos in general
