Passat (B6) :: Grayish Smoke Coming From The Engine Bay After New Downpipe Install
Nov 27, 2011
So I recently purchased a used Megan Racing 2.5" downpipe off a fellow Vortexer. Today I installed the downpipe and straight race pipe. After installing, my brother and I noticed a grayish smoke coming from the engine bay. Further looking revealed the smoke seems to be coming from the flex pipe mesh on the downpipe. What could be causing this??
Downpipe does not have a lot of mileage. No leaks. Brand new VW gasket was installed between the turbo and downpipe. Smell of smoke does not seem to be oil burning - seems more like a metal/gasket burning smell. Grayish color from what we could tell at night. Turbo still spools. No lights on dash.

i just installed my downpipe and i took it around the block and i opened the hood and there was smoke coming from the turbo could it be b.c i didnt put the washers witht he bolts to connect the dp but i put them on really tight or could it be the wd40 i sprayed on to loosen the bolts?

So this only happens one time a day when i do it. It does not matter if it's early morning or afternoon.
I pretty much give full throttle and i see in my back mirror grayish smoke coming out of the exhaust, kind of like when you are on a very dusty road. But i do it again right after or 10 minutes later and it does not happen again until the next day. Then it's the same deal.
I'm not doing anything different.. I do my oil changes every ~4k miles i drive mostly city with barely any stop and go tho. Is this something i should worry about and go see the dealership? Or is this because it is a GDI engine?
I did not have this with my old car even at high miles. But then again my old car was no GDI. I am currently sitting at 24k miles.

I have a 2005 Toyota Camry LE 4 cylinder, and I have been trying to figure out a hard cold start issue that also causes whitish grayish smoke to come out of the tailpipe when I first start the car.
When I first start the car after it has sitting at least 8-10+ hours the engine will crank over and being starting up but its almost as if it hesitates and then fully starts up. Once it does start the smoke will come out of the tailpipe for about 10 - 30 seconds and smells somewhat of burning fuel. I think the problem may be a leaking fuel injector. When I use my car during the day this issue doesn't happen at all after first startup
Coolant level and color : Normal no changes
Oil Color and level : Normal no changes
Tune Up: Done about 2 months ago
I uploaded a video to youtube of the car starting up here [URL] ....

I've been getting some grayish/blueish smoke on cold starts lately and decided to do some investigation to see if there was a problem or just the cold temps.
I googled it and turbo oil seal problem was pretty common so I figured it was easiest to start there. I removed the pipe between turbo and CAC and it had quite a bit of oil it in. The pipe after the CAC had a fair amount as well. I checked the oil level in the engine and it was slightly down but I can't say how accurate the dipstick is nor it was completely full after the last oil change. Either way, not much oil is entering the intake but I would assume any is too much.
Here's my main concern - What's the likelihood of getting a runaway from this?? Is it possible for the oil seal to fail 'more' than it already has putting more oil in the intake allowing for a runaway condition?
Obviously the turbo needs replaced but is it safe to run it the way it is until it completely fails or replace immediately?

I started smelling smoke after driving, so i open up the hood and theres smoke coming out near the engine....just to the right side...my temp read 190 which is where it supposed to be so where could this smoke be coming from? My bro who knows alot about cars said its not from the engine but does not know exactly what it is?

I've got this weird problem , it started a month ago. Sometimes I would drive for half a hour, park the car, stop then engine and some white smoke comes out of the hood after a few seconds. But sometimes I can drive the same amount of time, park, stop the engine but no white smoke.
The only time I did notice it happening is when my temperature gauge isn't working properly , sometimes it will give the right reading (which is right on the middle) and while driving it will drop to 0. Also sometimes there is a smell of rubber burning I think (Doing my best here). But I've checked Google for people with my problem but all I read is either people with tail pipes issues or smoke directly in the drivers cabin. My white smoke is only when I kill the engine. There is no smoke coming out of the tail pipe nor in my cabin. Only a rubber burn kind of smell.

So I just installed (well Strasse Autowerks did) my ECS downpipe with high flow yesterday, i have an 2010 GTI Unitronic 1+ and i've been using the car for an hour without any problem and then after that hour the check engine appeared and stays on in my dash.. some guy told me its normal because i have to upgrade to stage 2 so the error would disappear is that right??
And while being here i was also wondering, I'm going to have an intake later next week but what else do i need as equipment for the car for that upgrade?

As the title states I have lots of blue smoke out the exhaust and the smell of burnt oil. Checking other posts it looks like it could be a diverter valve, a pcv valve or the Turbo. I checked on line and autozone and parts America say these are not required for my car. I checked my Hanes manual (yes, that's all I have) and they don't have the DV or the pcv listed.

I have been searching online for days trying to find out why my car is smoking. i recently broke the oil pan on my 03 vw passat 1.8T. When I broke it I didn't know what had happened and I am sure all the oil drained completely out. The turn off engine now light came on and immediately shut car off! But I am not sure if i did in time before doing any major damage. my husband replaced the oil pan with a new one and everything seemed to be running good. i drove it for about 10 days and i noticed a whitish (I am not really sure of the color cause it was in my rear view mirror and couldn't see well) smoke coming from the exhaust as i was accelerating to get on the highway lasted about maybe 5sec then stopped. it has since done it 2 more times as i am getting on the highway but not every time. There are no fluid loss doesn't overheat when driving it all the fluids are good. I thought maybe head gasket or cracked head but husband says its not. the last it did it i stopped driving it in hopes to find out why its SMOKING!!!

I can smell burning oil and when stopped see oil smoke coming from the right front area. Theres absolutely no fluid on the ground ever even after sitting for days. I cant visually see any oil leak on the engine but I cant see the back. Im guessing its a valve cover leaking just enough on top of the exhaust on that side. Ive seen the gasket/plug seal set from $25 to $80. Some include the timing chain area gaskets/seals. Is that necessary to change at same time? Also, is there a gasket where the intake manifold and valve cover meet needing changed along with?

I just replaced my front rotors and brake pads this afternoon. I took it for a test run around the block and had allot of smoke come off the rotor on drivers side. I concluded that it had seized, and replaced it with a new rotor. I then test drove it a good two miles to fill the girl up with gas, when I got home I saw that my passenger side rotor had a faint amount of smoke. Granted I did a sloppy job and there was brake fluid everywhere. With all that being said, when I drove her to get gas it did not pull to the right, jerk or pulse. I was able to stop on a dime, I guess I want to know if this small amount of smoke is just the new pads adjusting to the new rotor?

My 2001.5 Passat traditionally does not start easily when it is less than 6degrees outside. Today it was that cold..it started easily..but about 30 minutes into my drive to work..I realized it was a little smoky and exhaustish smelling in the car..once I realized it wasn't the car next to me..i realized if I turned off the heat..the smell went away..but at the stoplight..i could see smoke coming from under the hood..out the corner by the passenger/dashboard... Car has 80,000, recent oil change, what it is?

Car was started for the first time after the radiator was flushed and new coolant was put on it. The car was just jumped and charged after was brought from a copart auction. Now my brother said that everything looks smooth, no xxxmas tree in the dashboard, idle is steady, engine sounds good.
Now here comes the thing, the temps of oil and water are at a proper level. When he steps on the gas pedal a few seconds later there is some sort of smoke coming out from the back of the engine (exhaust manifold, turbo, intercooler stock pipes from the SMIC) My question is cause he's not a mechanic and he will arrive tomorrow. crack manifold, shot turbo or some leak in the hoses?
aBtw the car has 105k miles.

Attached 2 images indicating where it leaks. This does not appear to be only leak but first thing first.
How to cure this. There is a number of stop-leak products out in the market: will they fix? Or should I change some rubber parts?

Took about a 200 mile trip this weekend, stopped at a rest area about halfway through and smelled burnt carbon, smelled like a burnt clutch almost. It was very strong and there was smoke coming from the engine. It wasn't a lot but it was cause for concern. I checked the oil, last oil change about 1500 miles ago but no problems there, temp gauge was in the middle. Let the car sit for a 10 mins or so and then headed of again. When I got home that night, couldn't smell it and there was no smoke. Car has 42K ... Also, I got an airbag fault light about 30 mins from my house.

i have an 06 phaeton with 32 k miles . drove home with no problem at all, no engine shake, zippo. then i put my car in the garage and 10 minutes later smelled like a fire. i pulled my car out of the garage, and the yellow light was flashing and the engine rocking like crazy. shut it off in less than 10 seconds. under the hood, the front left spark plug cover and cable that runs across all four was almost completely melted. the cable was burned right thru. the black caps that cover the plugs-- the front right one only was melted severely. Do I have a blown engine...

As I was about to pull onto the highway I noticed smoke coming from my engine. I pulled into my mechanic. The antifreeze was empty. He filled it but couldn't find a leak. The next day I found antifreeze on my garage floor. I brought it back but he still couldn't find a leak. He thought he might have spilled some when he filled it. It is now two weeks later and the antifreeze is still leaking. I see it when I pull out of and into my garage when I momentarily stop to open and close the door.

1998 Passat 1.8T Sedan, Manual, 118k miles, new head at ~ 87k due to broken timing belt. (Changed oil approximately 1.5-2k miles ago, no loss of oil evident). No noticeable loss of power. No MIL and no DTCs in storage.
But there does seem to be a bit of exhaust (puff....puff.....puff...) that seems to be coming from under the turbo side of the engine, but it is hard to tell.
Recently - over the last couple of weeks - noticed at start-up in morning, significant amounts of blue smoke from exhaust - eventually subsides to nothing after a couple of minutes. BUT, it only seems to appear when the car is angled with its nose slightly up in the driveway and not with its nose down. Lack of it occurring with its nose down was only tried twice; I may need to check it again.
After reading many posts, I thought it might be:
1) Oil overfill at last change - I noticed that my oil was less than 1/16" above the top bend. I doubted that would be the problem, but I siphoned off the small bit and it is within or just below the bend now (hard to read). It might be the oil since I used the Valvoline full synthetic MaxLife that is VW approved for the first time, but I find that hard to believe since I have been using synthetic for a couple of years now.
2) Oil getting into the combustion chamber via oil in the turbo system. Checked the low spot in the hose just before the throttle body. Seemed virtually dry; that's not the problem.
3) I guess it could still be oil gathering some place due to the failure of the turbo, but power seems quite normal.
4) Problem potentially with the PCV (actually called the breather and bleeder valves) and/or vacuum system being plugged up. After reading all of the posts regarding that I am starting to think (HOPE) that is it and not the turbo. While I do understand that flapper valves that are stuck would create greater pressure which could result in oil being forced into the chamber past the valve seats, I am not sure why the angle of the car while parked would matter since the higher pressure would only be occurring while driving; and the blue smoke goes away after driving and doesn't appear until next morning. But perhaps I am missing something.
Particularly which valves I should check/clean if I am seeing this smoking exhaust at start-up, but only when the car is parked with the nose up?
5) Sticky valves at the back-side (cabin-side of the engine)?
