IS F (2008-2014) :: Car Started Smoking Bad From The Exhaust
Nov 6, 2013
Went to a road course for the first time on Sunday. After about 10 laps the car started smoking bad from the exhaust. The smoke was thick and white. There were professional drivers present (driving school) as well as a lexus service manager there looking at the car after the run. The smoke was thick but without that sweet smell of coolant. This was the hardest the car has ever been run but also maintained normal oil and coolant temperatures. After a bit of resting the smoke cleared up and never came back, my drive home was 2 hours long and car still seems ok. Engine sounds good, oil very clean, what could it have been? I have no cats so its going to be more obvious than normal.

My '06 Ford F-150, 4.6 V8 is smoking when I start it up occasionally. The smoke color is blue. The only mod is flowmaster exhaust. Bad injector, sticking valve......
Where would you start? I am all for supporting a local mechanic but financially I do not have the money to gamble. Once I can pinpoint the problem I will take it to them to fix.

My bro just got a 1999 passat 1.8t and it seems to be smoking really badly from the exhaust. We checked the air intake for oil. But that seems fine. Where its going bad?

My son's 2001 LeSabre (3800 N/A) was smoking under the hood and the odor was entering the cabin. I decided it was likely due to coolant and oil leaks from the valve covers and manifold gaskets as well as a crack in the upper radiator hose. So I replaced all the gaskets and hoses and cleaned it up some.
After a test drive, smoke still coming from under hood. It appeared to come from the exhaust crossover joints (mainly front) and possibly from the seam on the crossover "shroud". I suspected some rust damage to the crossover, so pulled it out. (And spent my Sunday digging out a broken bolt. )
I don't see any visible rust on the crossover (but can't inspect the entire thing visually). Could it be a clogged catalytic converter causing back pressure and the leak? Or is it more likely something under the hood like a head gasket. (I hope not. )

I shift at certain rpms from 1st-2nd just to hear the burble / popping out of the exhaust.. I hold it around 3k and the shift and let off the gas and it's a Orchestra of amazing noises that are Oh so addicting. Secondly, are there any negatives to doing this? Or that sometimes I hear the loud thud / pop when slowing down but not everytime . What is the true cause of these glorious noises.

I've got an '02 F150 with a 5.4L Triton. Despite being 10 yrs. old it's just passed the dealer warranty mileage about 80,000 miles. Due to a family situation it's been sitting idle for upwards of 2 or 3 weeks between startups.
When I do startup there's a puff of blue/geyish smoke, the engine idles rough for about 30 secs. and then everything smooths out and she runs normal.
I haven't noticed this issue before, I would add the temps here have been extremely cold the last few weeks. What direction do I point a mechanic in so he doesn't waste time or money on a diagnostic.

Having a sound from my exhaust. Basically when the car is rolling along around 25 MPH or so, and my foot is not on the gas, as soon as I gently touch the gas pedal, I get a soft "thump" sound. This basically tends to happen in 5th or 6th gear only.
The previous owner had done a muffler delete on the stock exhaust so I figured there was some sort of back pressure issue because of this.
Finally out of frustration, I sprung for a new Borla Catback exhaust system, hoping to eliminate this issue. While the thump sound is slightly less, it still happens!

Been researching exhausts a bit and getting information about the full PPE header and PPE Dual mode exhaust to review?

So I just wanted to ask 2 things.. Am I the only person who purposely shifts at certain rpms from 1st-2nd just to hear the burble/popping out of the exhaust.. I hold it around 3k and the shift and let off the gas and it's a Orchestra of amazing noises that are Oh so addicting. Secondly, are there any negatives to doing this... Or that sometimes I hear the loud thud/pop when slowing down but not every time... What is the true cause of these glorious noises.

I have a question with aftermarket exhaust (particularly JoeZ and Borla) I was wondering after you installed the exhaust do you now get increased exhaust fume smells in the cabin when the windows or moonroof is open? When I had my 350(F-sport exhaust) I couldn't cruise with the moonroof open without filling the cabin up with fumes.

So I believe I have a crack in the Exhaust Manifold... When I rev the car I can hear a slight tick. I had taken it to a shop to do a muffler delete and said that there may be a leak or crack somewhere. The tech said it wasn't too bad but it may be something to keep an eye on. My question is, what would be the best route to go? Is this a common issue with the ISF? I was thinking if it was also possible if it may just be the gasket, which the tech also said it could be. I have a 2008 model with about 113k miles on it.

I have a 90 celica, and while I driving today, the engine started smoking. I pulled over and took a look. The smoke was coming from behind the smoke and air filter area. I let it sight for about 2 hours and drove it back home and it wasn't smoking. Both times, it was on the road for about 20 minutes. I got a buddy of mine to take a look and he said that it was caused from the coolant boiling(I didn't think coolant coils boil). And it rained for a week straight, and I haven't driven it since it started raining. Could that have anything to do with it?

My car has 343,000 miles and runs great. It has recently started smoking, but only does it when the engine is cold. I've heard that it could be the rings, and to buy an additive that I could add to the oil. I go through about a half a quart for every 500 miles. I'm not expecting the car to last forever, but I was wondering if it would be beneficial to buy the additive.

just recently installed the new X force exhaust system on my 2008 ISF with 72,000 miles on it. I've had the exhaust on the car for about 300 miles it when I was driving home from work today the vsc and check engine light pops up. I turn the car off when I got home and then turned it back on the check engine light was off but the stored Code was still there when I read it with the scanner P0420. I'm thinking maybe there's an exhaust leak even though it sounds fine.

89 toyota truck 4x4... A few weeks ago I had my truck in 4wd and was reversing, I stopped and tried to go into first gear. I found that the shifter would not engage, I can move the shifter around 360 degrees with nothing catching. I checked under the shifter boot and thought it may be the bushing that is shot. To feel safer anyway I decided to have a friend tow me to pavement and have AAA tow me into town, as I live 7 miles down a curvy mountain road off grid. As i was being towed out today the truck started spewing black smoke from about where the shifter is underneath the truck. Freaking out, we stopped the tow and i coasted back down the hill into the driveway.

I parked my 2003 f150 about 8wks ago, and at that time the blower had been running only on high then not at all, then only on high again.
As I need it to pull the boat up north next week, I purchased and changed the resistor. When I started it up the blower motor wouldn't run and eventually it started to smoke, so I pulled the wire connector to the motor.
Where I can find a procedure for motor testing, and removal as I think this is probably where I'm headed with this. There seems to be utube videos on everything else but not this. I may just have to go out and purchase a Hains or Chilton manual but I'm Scottish and always look for the free route first.

I recently did the NAV/DVD bypass. It worked fine and still does. Although the check engine and check VSC warning came on eventually, I reset them and did not recur and all is fine with the bypass not activated. After about several days or a week later I tried the CD player and the audio started cutting out as well as no audio from the DVD. All CDs and DVDs worked before. AM/FM/SAT/NAV audio works fine. But DVD/CD has no audio.
I found that DVD/CD audio go through the optical S/PDIF (spdif) cable. I checked it behind the unit and it looks fine, undamaged, not bent. I have not checked it on the amp side yet. Also I do not know if there's anything in between.
What the S/PDIF cable line consists of?

I just bought a 2002 echo recently and it started smoking blue. The car has 135000 miles which seems low to me to be blowing smoke so soon. I grew up around cars since my dad was a mechanic so I checked the compression on a cold engine. Cyl. 1 was 117psi, cyl. 2 was 134, cyl.3 was 127 and cyl. 4 was 117. I realize they are low but the car is blowing a pretty good amount. The car drives pretty good overall and seems to have power, i drove it on the freeway a few times and did 80mph fairly easy. I was wondering if this could possibly be valve stem seals gone bad? I will check the pcv valve as well. I really like the car and have read a lot of good things about the echo.

2007 f350. About 2 weeks ago my truck started smoking really bad, and I took it in to have it diagnosed. It was 4 injectors that were bad, so I had them replace all 8 and also install a bullet proof oil cooler. From the moment I got the truck back, it did not seem to idle as well as it used to, and over the next week, it began to blow a good amount of white smoke and run very rough.
But the weird thing is when I took it back to the shop to have it diagnosed, the minute I pulled into their driveway, it ran perfect, and they were unable to pull up anything. The next morning, I started my truck for work and as I drove down the street, the truck ran extremely rough, and seemed to be running in 2 cylinders. I shut the truck down, restarted it and it ran a little better, as I limped it back to the shop.

Was doing nitrous passes the other day and all of a sudden the car started to lose power. I let off the gas and the rpm's got lower and lower, until I cut the car off. Let the car sit for a bit and tried to restart. Car will turn over but will not start. Threw two odes p0300 random misfire, and p0101 mass or volume air flow circuit range/performance problem. I also smelled slight burning for just a second. I am thinking it has to be MAF or a burned up plug. Has to be air, spark or fuel related. Any of the nitrous guys out there ever run into anything like this? Want to eliminate the small things first. Hoping there isn't a larger issue.
