so i just installed a greddy turbo kit on my 08 civic si and wen i 1st started it up and step on the gas petal it smokes white/blue and its crazy amount. i also let the car run for lioe 20 mins and still smokes..im think the turbo seals are bad but there is no shaft play is that possible..oil feed and return lines are fine only thing is car isnt tuned yet and will be tuned on flash pro do u guys think that could be the problem? i also check plugs no oil so its not the motor. my tuner said he took it down the block and it smoked bad so he said turbo is blown what do u guys think?

 

you just installed the kit, so go drive the car around and put miles on it and it wont smoke anymore. its the same thing when you put on a race header, or a new exhaust. it smokes because theres a thin layer of oil or some stuff they put to protect it from corrosion. once that layers burns off, voila!! no more smoke!

but if the smoke doesnt go away after a few days of driving, refer to this.

white smoke is burning coolant.
blue smoke is burning oil.

 

the turbo kit was used i forgot to mention that...

or in between?

have u checked your oil?

 

i did check the oil...im guessing could be the oil return line or feed line but i high doubt that a oil filter sandwich adapter causes that much pressure.. i didnt rev it alot cuz it smoked bad but if i had to say it would be closer to one since the 2nd vid didnt rev it .

 

your turbo could be bad.

to determine, are you getting smoke out the downpipe/exhaust then turbo

under the hood then its the oil return or feed line.

 

it all coming outta the down pipe and exhaust but thats from a cold start would. would it still smoke under hood if it was retrn and feed line from a cold start or would i have to let it warm!

 

Oil return lines are gravity fed. So you need to have it mounted as high as possible in the pan and above the oil level in the pan or oil will get backed up and not be able to flow into the pan. Also you want a straight path with little or no bends or 90 degree fittings.

There is not a good place to tap the pan on our motors. I'd like to see where you tapped the pan. The best place I believe is above the drain bolt as close to the pan's mounting surface. I actually had to relocate mine because on start up I would smoke a little until the oil was circulated through the motor.

Also I like to keep my oil to the top line which makes it worse because the oil level is above the return entry point in the pan hindering drainage. I found that if I kept the oil level at half between the two dots it smoked less. A little blow by through the turbo isn't the worst thing. SRT had an oil catch can that was meant to remedy this but it didn't work as designed either. This engine was not designed with a turbo so they didn't allow for a nice location for an oil return. My WRX oil return is really high in the oil pan but it had a turbo from the factory.

 

if it was the oil feed or return would it smoke under hood or come out the tail pipe?

 

Under hood. If it is the lines they could be leaking and the oil is going onto something hot, such as the downpipe, causing smoke under the hood.

 

theres nothing under hood just white clouds coming out tailpipe

 

Under hood if it's the fittings going into the turbo.

Tail pipe if it's blow by of the seals inside the turbo. The oil is for the lubrications and cooling of the jernals. If it's backed up it will push past the seals and enter the exhaust, burn then smoke out the pipe.

 

its coming out the tail pipe so i take it for as a bad turbo seal so im sending the turbo out to blouch turbo to get it rebuilt. not out of the hood the feed and return line should be find straight up and down like it supose to..

 

I wouldn't send it to blouch yet. A brand new turbo will blow oil by the seals and smoke if it can not drain properly due to the return line not being mounted high enough on the oil pan. Alot of people don't mount the return line high enough in the pan. It's a common mistake. Do you have a pic of your oil return location on your pan?

Also some turbos are not re-buildable.

 

The kit he bought was used, and it's a Greddy so assuming that it's the turbo the kit came with; it's rebuildable. It's probably worth the cost of the rebuild anyway.

 

Just curious what kind of turbo came with the kit? If I had to do it again I may try a garret gt28r or a 30r. It would be nice to start to build boost at 2500rpms. I get nothing at all until 4000rpm but it will not run out of breath like a 28r. It's hard to select a turbo for our motors since they rev to 8000-8500. If you pick a small one it will spool early but run out of breath at high rpm and a large one will spool late and explode at high rpms which is very fun. Mine is awsome at highway but leaves me wanting at stop lights at low rpms.

 

the turbo is a t517z my installer said the oil is fine im running the stock greddy oil lines..banjo bolt return line do u think oil can clog up and hard in the hose?

 

Never heard of that turbo. You said the oil return was a banjo bolt? Do you mean it returns through your drain bolt?

 

yes it does return thru the banjo bolt. gonna get rid of it soon

 

No, I'm asking if it returns through your drain plug in the oil pan? If so your turbo is not bad. It's your return that's the problem. You need to relocate that and tap the pan. You will still smoke if you rebuild the turbo.
Remember my earlier post. If your oil return is below the level in your pan it's no good. Also the diameter of the oil return is supposed to be 5 times larger than the oil feed minimum. So if you oil feed is 1/8" diameter your return must be 5/8"

 

i understand but i was told if it was the return line or even feed line i would smoke under the hook which i am not. the shop that my car is at now has the same SI i have wit the same kit still running the banjo bolt which no smoking under the hood or tailpipe. i took under consideration that i got the greddy kit wit everything for 500 bucks so there has to be something wrong and the seller did not tell me.my turbo is coming off tomorrow and im gonna check for oil in the turbine and down pipe and such. but i know where your coming from im just 90% sure its the turbo.

 

500 for everything?? holy crap, you got shafted.

 

i wouldnt say i got shafted the kits go for 4500 brand new i got everything wit the turbo kit intercooler,piping,manifold,downpipe, and the turbo return and feed lines, and a greddy type rs BOV for 500 bucks is a steal in my book even if the turbo is blown.

 

4500??
yea i dont think so.
i can get the greddy kit installed for $3800.

 

well i got the kit for $500 and my install was $550 and i need injectors which were $300 that puts me at $1350 installed...the kit is already installed and done but now its smoking and a turbo rebuild is $300 puts me at $1650 im still saving $2200. but i run into headace of tryna figure out the problem. which i rather deal wit then forkin out 2200 more bucks
