I am only at 141,000 miles and I'm seeing blue smoke while I idle! It started as a small puff of blue smoke when cold starting up...now it is much more consistent. I am also getting a diag trouble code of P0674 (glow plug in cylinder 4) can that be the cause? I'm nervous since I didn't watch my tech put oil in the truck at the last oil change...I think he put four gallons in instead of 15 quarts...is that a prob?

Yesterday went to get on the freeway I looked back and saw a cloud of what looked like blue smoke. I'm in northern Utah and it's cold but the truck runs fine, I haven't noticed any change in performance. Turbo still builds boost. I pulled the fuel filter cap last night to check fuel color and it was clean.
I do have the CCV mod done. I also pulled to IC Pipe off the turbo and there was a little oil in there but not much, should there be any at all with the CCV mod? Where to start.
First some background. The vehicle is a 2003 Expedition with rear AC. The 5.4L engine has been replaced with a 4BT Cummins (DD since 2010), but the AC system is not altered-- other than the compressor being mounted to a different engine. The intercooler is in front of the condenser, which hurts efficiency of the AC system, but it seems to work fine in our climate.
My AC system quit cooling one day, and the problem was a hole in one of the low-side tubes from rubbing on the turbo-to-intercooler tube. I repaired this by aluminum brazing. The system held 120 psi on nitrogen for one hour. So I pumped it down overnight to 27 inches of Hg and made an appointment with the AC shop to get it recharged. I could not get an appointment for several weeks, so I continued to drive it with no AC, thinking it should be no problem since there is no pressure in the system.
I was on a road trip when all of a sudden, there was a huge stinky cloud of blue smoke billowing out from behind the truck. I pulled over and the AC clutch and pulley was smoking hot. I shut it down and cooled it off slowly with squirts from a water bottle.
So my clutch is shot but I'm not sure what caused it to fry. Is there a typical mechanical failure where the friction material can be chewed up by the pulley-hub? Or is it possible that somehow the controller commanded the clutch to engage without pressure in the system?
I think it would be prudent to replace the compressor, since there may be some bearing or housing damage from the clutch failure, so that is in the plan. I have read that when ever the system is open, the drier should be changed too. I want to do this right rather than do it again on another day.
One concern I have is that if when the clutch was failing and it managed to turn the compressor-- could there be pieces of compressor in the tube runs that I need to clean out? Other than a visual inspection of the open tube ends, is there another test or things to look for?
I have a 2003 ford escape V6 and i have notice when i start it' after setting overnight i notice some blue smoke for a little while then it's stop What could be causing this.
View 1 RepliesI may have an issue with my engine. My car is beginning to blow some blue smoke when I romp on it. It doesn't break up at all, there isn't any loss of power. It's just blowing some smoke and I noticed a light oil build up on my exhaust tips. I don't think I need to be hugely concerned yet, but I am bringing it to the dealership tomorrow just to make sure.
View 9 RepliesI have a 07 6.0 powerstroke, I had 2 bad injectors so I replaced all of them with reman's. I had a problem with them coming loose. the first time this happened it hydrolocked the motor, number 8 cylinder. so I pulled all the injectors and replaced all the seals and washers and torqued them down a little more than spec like 27 lbs. it runs great and starts great even at 25 degrees but I noticed this morning that when starting it up after it sits (cold) it blows blueish smoke until late it warms up and I accelerate. is this normal? should I check fuel filters? oil in fuel?
View 14 RepliesI have a 02' Limited V10 with 202xxx and have come across new issues recently.
Occasionally when I start up the truck it spits out blue smoke BUT its only when it fires up then it's done.
My turbo started to have oil on the top of it. I don't know where it's coming from at all, it started to blow blue smoke but not all the time. You can also smell the oil burning off.. someone said maybe the pcv system but not sure. Still new to the vw world only owned the car for about 4 months. Trying to add pics but it's not working.. Will keep trying

View 1 RepliesI noticed a few puffs of blue smoke a while back as well as oil at the seam of the exhaust tubing. I attributed it to bad turbo oil seals and proceeded to rebuild the turbo. Changed oil at the same time from T6 to T5, 15-40. The blue smoke is quite a bit less, but still shows at idle and not all the time.
First start up of the day, slight haze. I leave the house when the oil temp gets above 100 and drive easy until it gets to 160. I will get a pretty good train of smoke until the oil temp gets above 180 at every stop while I'm idling. When the oil temp gets above 180, it will only smoke every 3rd or 4th stop at idle. If I hold the brake and get the RPM's over 1,000, the smoke dramatically decreases, if not completely dissipates.
I do have the CCV rerouted and am wondering if it is affecting the operation of the engine.
97 f150 4.2 ... Got a pickup awhile back and was smoking excessive mostly blue. Pulled the motor and had exhaust valve with hole in it and intake valve not seating on separate cylinders. All new gaskets and put back in truck. Deleted catalytic since they were both destroyed and cleaned muffler as best I could. Now it smokes but mostly white when revved up and maybe slight blue at idle. It's not using coolant or oil but went through five gallons of gas in short time.
Tests I have done : Checked fuel pressure and holds 38 psi all day. Tested maf o2 sensors, one is bad and tested vacuum and compression all good. It seems to be over fueling to the extreme. idles a little rough and will backfire on occasion. No check engine light but had all the o2 sensor issue codes. I'm leaning toward bad PCM... Would that cause the smoke rough idle and super rich condition??
I am writing about a 2007 Chevrolet Suburban and for the last few months, have noticed that the car is losing oil. I have to put in a quart of oil about every 3 weeks. I have brought it in to the mechanics and asked them to look for a leak and they can't find anything. They have changed the oil, replaced the evap hose, but the car is still losing oil. Just did a lot of driving this last weekend and the oil went all the way down, to the point of when I started it this morning, I got a huge amount of blue smoke out the back. When I took off the cap to add oil, I noticed this mustard yellow, foamy stuff on the lid. Never saw that before.
View 6 Replies2004 f250 6.0, 173k miles. I just had the head studs done and a new head due to a crack in one head, I got it back 3 days ago and she was running great. I towed my landscape trailer yesterday full of mulch and only went about 5 miles with the load, after the job driving to another one I noticed it sounded like it was missing at idle with a small amount of white smoke. Drove it home let it sit overnight, started it up this morning and a cloud of white/ blue smoke and a horrible rough idle. Smoke does not stop.
View 10 RepliesMy cars runs great no smoke unless i let it idle for a while then go there might be a little white smoke or blue smoke just depends, doesn't do it all the time just random, my oil is perfect no water in it so I don't think headgasket, its running a precision 50 trim bigger injectors and full 3 inch exhaust.
View 3 RepliesEarly 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild
View 9 RepliesMy v10 Ex blowing black smoke, RPM goes up and down, when put it in gear stalls and dead, engine is shaking and all this happened after one small 80mi trip, it was perfectly running until I turn off the engine .for almost 2 minutes. So what to do ?? And there is no code .
View 6 RepliesWell my problem went from bad to worse. My 05 started running rough at idle, then smoothed out a bit but started smoking on acceleration a little. At this point it felt like it had more power than ever before and even ran smoother running up to 3k RPM before shifting (manual transmission). But now it's smoking so bad, I can't really drive it. It's smoking white or gray at idle but blowing black smoke on acceleration. I had a cylinder 5 contribution code but with the amount of smoke it's hard to believe only one injector is a problem. I pulled the EGR valve and it doesn't look stuck open but I'm going to replace it anyway.
View 3 RepliesCar: 88 festiva with 227K miles For those unaware this is a Mazda B3 SOHC carburated 4cyl
Symptom: Misfire and Blue (oil) smoke.
When: Only happens at first startup after car has sit for a while (at least 8 hours). It starts ok, runs fine on all cylinders, for about 15 - 30 seconds. Then it starts to misfire. If I try to drive away I get a cloud of blue oil smoke. It then clears up and runs fine. No oil smoke, no misfire. If I just let it idle, it will misfire for a long time, and then blows even more smoke when I finally hit the throttle. It really only seems to clear up if I rev the engine a bit.
I have adjusted the valve lash, changed the oil and filter, replaced the plugs with NGK copper. Dist cap looks newish as well as wires ( but I have not changed them)
When I pulled the plugs, they looked fine for the most part. no fouling, color looked normal, they weren't worn horribly.
I initially thought that it was a carb issue, but the smoke has gotten worse, so I am thinking maybe something is sticking? I get some clatter at startup sometimes (not valve noise) but it goes away as soon as the oil gets pumping (like 1 second) and it is pretty inconsistent when that happens. I am still getting over 30mpg in mostly city driving, and power levels seem ok most of the time
I am leaning away from valve seals, because in my experience they dont cause misfires and for the first 30 seconds there is no smoke at all, but am I in the wrong here?
I picked up a 2001 ford ranger with a 2.3 from a friend of mine for next to nothing. it has a serious oil consumption problem. he just put a head gasket in trying to fix the problem with no luck. he thinks it has a broken oil ring. the truck only has 99xxx miles on it and i find it hard to believe that it broke a ring. I am thinking it has to be something like a bad pcv. If it is rings ill do the job but I don't want to pull the motor down just to find that all the rings are good and it was something that i looked over
View 11 RepliesI've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.
View 1 RepliesAfter tooling around town and a complete warm up cycle for the engine I encountered a problem. The situation is this.... Had to go around a slow poke....waited until traffic had cleared and nailed it. My truck belched out a boat-load of blue smoke from the tail pipe. Could not duplicate this on the return trip to the stealer (Dealer). Needles to say, I am worried about the health of the engine....(no codes popped, or anything else as I had a code reader hooked up) My truck did the blue cloud again with a rev up in park after a cool down but wouldn't do it again, but there was a strong smell of unburned fuel at the tail pipe.
