eg9d16turbo

i just picked up a single overhead cam turbo car d16 to be exact.. text drove her pulls hard seen nothing herd nothing running on 5.5 psi i havent even spooled her up real hard just standard speed up to merge on freeway later that night on the way home getting off the freeway and at stop lights seen white smoke little from under the hood and a ton out the rear, when i got home nothing no smoke at all. while at light smoke seemed white and exhaust seems to rich, rich enough to smell, where should i start?? im new to the turbo game.....

Get it tuned. What does your wideband say? What sort of engine management are you running?

RATED RX-7

Correct me if I'm wrong anyone, but white smoke usually means the seals on the turbo are going out.

im not sure how can i find out i literally got her last night guy i had gotten it from was a 50yr old who recived it for work done...

Not really. I got an ECU with a real crappy basemap on it running absolutely too rich and it chugged smoke like a steam locomotive.

Blown seals are usually indicative of too much oil pressure.

i noticed you also have a d16 turbo what type of engine management would you recommend??

Whatever you can afford. Stuff like Crome is free. AEM I've seen priced used at about $600-$700. Find out what your local tuner uses and run with that. I didn't do that, got a basemap on Crome and the guy I took it to wasn't all that familiar with it. So I'm not running with the tune I would like to have. He was a Hondata man. I'll probably make the switch to that come spring.

So again. What engine management are you running? Wideband?

White smoke is generally coolant. Blue smoke is usually oil (turbo seals would fall under this category)

Dude! someone help figure this out! I helped a buddy build a ITR and we keep getting the smoke out the *** issue.

Setup:
JDM Type R:
Head has all skunk2 valve train done by a shop
Block has 9.1 CR JE pistons and new piston rings
eagle rods
ARP Head studs (torqued down to 82 ft lbs in steps)
Cylinder hone showed no cracks in the cylinder walls
Head gasket used 2x
Turbo setup:
Hybrid T3/T4 turbonetics/garrett (just refurbished last week at Turbo masters san marcos)
Ramhorn manifold
Tial wastegate
off brand BOV
all custom intake piping
FMIC
3" downpipe
AEBS ITM
BDL 69mm TB
Hondata s300 (untuned)
dunno what his injectors are but they are the ones that you just press on the sides to take off instead of removing that horrible wire clip (he has 440cc rc's but are not installed)
Holley FPR


Someone help! im just burnt out and need some fresh heads on this one.

To the op. im pretty much having the same prob as you so but i just gave more details. So if mine gets fixed, yours gets fixed and visa versa

After the first time it started smoking we honed the cylinder (didnt do it the first time), Had the turbo refurbished and it still smokes! everything else stayed the same. everything is torqued down to specs and we couldnt spot any defects. Also we went from a dash 4 fitting on the oil feed to a dash 3.



Update:
i remember noticing last night that there was oil seeping through the turbo manifold (between the manifold and the head) and through the gap in between the manifold and the turbo. Headgasket? valve seals? I just want to see this run and get tuned. (tune shop said they cant tune a smoking vehicle).

I know you said you just got the turbo rebuilt but it sounds like the seals are blown already. Are you using a restrictor?

kaduku_

we have a dash 3 fitting on the oil feed right before the turbo, that counts as the restrictor...right?

grumblemarc

No. Also make sure your oil return lines are set up correctly. Not too low on the pan and as straight up and down as you can get them. Otherwise oil could be backing up into the turbo.

I've heard mixed opinions about not needing a restrictor for a line as small as -3AN but I run one anyway just to be safe. My oil pressure is pretty good and to top it off I have my oil pump ported.

grumblemarc, im going to have to send you some drawings of how it is. This might accually be the issue. Please pm me your email, i reply faster do those. Thanks in advance for any help.

Pics work too. PM'd.

kaduku_

anyone else?

speedooo

this is not your topic...go make your own...

grumblemarc

The OP hasn't answered any questions put to him.
Tune?
Engine management?
Wideband?
How about as much information about the car as you can possibly provide?

speedooo

I was referring to Kaduku who is making this into his own topic.

If it burns oil at idle it's going to be the seals in the turbo. If it happens continually with new turbos you're doing something wrong. It's as simple as that. Take the feed/drain lines and blow air through them, try to drip oil through them, put an inline pressure gauge on the feed to make sure it has some pressure...do something.

foo fighters

you have blown head gasket??

grumblemarc

How do you figure head gasket?

I had the same problem with my single cam. After a good - casual ride, come to a stop and smoke would appear from my hood. The smoke seems to be coming from the turbo and it didn't smell like burned oil too much. I took the turbo off and found out that the turbo isn't sealing correctly (minor oil leaking). I didn't want to rebuild it so I had switched it out with another one and that solved my problem. Don't know if this helps but it at least it's from another point of perspective.

i think its the seal on your turbo.

I'm not trying to cause waves, but the guy never answered any questions. Kind of pointless to ask if you don't take the time to respond to people trying to help. Just saying
