Smoking out the Exhaust

[blueman803]

I am trying to troubleshoot this smoking problem. It was putting out a smoke screen at idle. I removed the intake from the throttle body so that is pulling air straight in and bypassing the turbo. The smoke went away until the engine warmed up. After the car warmed up, it started smoking/steaming. Could the smoke in this video just be condensation, or is there something that can cause this smoke at idle and not increase when revved? Car is far from stock. The car is definitely spitting out a good bit of condensation.

1)Speed Density System
2)ISC Fiav removed
3)EGR removed
4)3" Exhaust with no Cat
5)Balance shafts have been removed

Engine was just overhauled 1000 miles ago and the turbo was replaced with a brand new to4b v-trim. The oil feed is from the oil filter and does not have a restrictor. I have checked the PCV valve and it is clear and the oil return line is not kinked. Spark plugs look like there is some carbon buildup, probably from the turbo seals.

if it is a white-ish smoke inwitch it kinda looks to me,I would think it is a head gasket. I am sure some one will chime & confirm or give another possible option.

White Smoke= HG
Blue Smoke =Rings, Turbo, ECT> oil in general.

I am sure most people will tell you to do a compression & or a leak down test & post those & then it will tell you more spacfic.
hope this helps

Do a compression and/or a leak down test and post the results. Then we can be more specific with our answers.

Is the smoke constant or only when your driving because i have a bad 14b turbo right now smoking blue smoke at first start up and smoking a lot under boost due to bad seals in the turbo...

 

[dnbmovement]

u turbo hasn't gone bad from the looks of it. i saw clouds of smoke that screens the entire street. Im betting head gasket ftw

When I had my 93 N/T it smoked, and it ended up being valve seals. Does the smoke smell, and if so what does it smell like? Good luck!

 

[blueman803]

Smells kind of sweet. I'm betting hg, but I will know tomorrow morning or this weekend when I can run the compression test. Any chance a leaking hg won't show up in that?

The smoke is constant at idle. It will not start until the car hits roughly 170 degrees. Then it will start in small spurts and turn into a fairly decent smoke screen. There is a hint of blue in the smoke as well.

Yeah from the sounds of it you may have yourself a HG issue (welcome to the club). do the compression test & if possible do a leak down test, if you are still not sure (or just want to cut straight to it) take the vale cover off & look for Chocolate milk A.K.A coolant in your oil.

It is probably a head gasket due to the white smoke. The white smoke can be coolant burning so pull the head and replace the gasket. Also try a compression test and see how they match up to what they are supposed to be.

Compression Test = 5 min
Poor Mans Leak Down Test = 5
Changing HG = several hours

Doing tests before taking the top half of the engine off = timeless.

(ok that was goofy. shut up)

I would do compression and leak down tests before you take the top half of the engine off.
There is a very good chance it is the HG, but as mentioned, it takes almost no time to be sure.

on start up and about the first 5 mins of warmup my car doesn't smoke during idle, but if I rev it blue/whitesh smoke comes out, and today went I was driving when I got into boost a tad bit I could see a blue little screen of smoke left behind me on the road lingering around. Does this mean my turbo seals are going?

 

[MrBoxx]

Did you check your turbo for shaft play and pull off the lower intercooler pipe to check for oil pooling in it?

 

[nightspeed87]

i say turbo seals, sounds like your describing my car....

 

[blueman803]

Compression test done while warm. I see no reason to continue with a leakdown or wet test.
1-180 2- 185 3-185 4-185

Any ideas what it could be? Definitely do not think its my HG. The engine runs very strong, no misfires or anything indicating oil or coolant contaminating the combustion chamber. Does synthetic oil in the exhaust burn white or blue? I'm wondering if it is the oil leaking through the turbo seals out the exhaust side.

HG symptoms, oil in over flow bottle, lack of power, smoking out the exhaust, loosing antifreeze through exhaust, overflow bottle increasing in antifreeze, loss of anti freeze. If it smells sweet all the time is most likely anti freeze your smelling, my buddys car smells like that all the time and the hg gone.
