Blue smoke, oil burning.... Cause and effect?

[DodgeZ]

Okay I am trying to make an FAQ as it relates to our cars. It seems everyone of our turds burns oil at some point. What I want to do is use FACTS to help with troubleshooting. When I say facts I mean it IS fact what was caused the smoke and what the car was doing.

Here is an example of a fact:

I pulled the head off to find the valve seals cracked, My car smoked on start up, once I installed new valve seals it stopped smoking.


Here is an example of a junk post that you will be made fun of for posting:

My car smoked a bunch when I came to a red light. It was the turbo. I scraped the car out for 200 dollars before I change the turbo but I am sure it was the turbo because frank at the muffler shop said it was the turbo and he is a really smart guy....


I am going to start off with some basic questions we can add to it if we need to. If you don't know some of the answers just say that you don't know.

I've got the smoking part on start up and it smokes quite a bit
while it sits and idles. Haven't figured out why yet.

It's a 90 VNT

Post update when you get it figured out.

[TurboII]

i had no smoke and start up and after 5min it smoked bad....turned out to be a bad turbo

[cordes]

Smoked once car was hot enough for DP to burn off oil. Replaced turbo, smoking stopped.

This was in my 90' shadow which had a TII turbo in it at the time.

Not a problem that i have PCV valve is a common problem for smoking

Please explain what your car is/was doing and the cause here: Once warm, would smoke bad on deceleration and at idle afterwards, then blow a huge cloud of smoke out on take-off and be gone until the next stop. Turbo seals were bad, replaced the turbo and it never smoked again.

[Keito]

After I would drive my SRT-4 for a while, shut it off for maybe 10 minutes, start it back up and would get a big blue cloud .
Did not smoke on start up when it was cold.
Car had < 10,000 miles on it.
Turbo seals were shot.

(It was an aftermarket big wheel stock turbo)
Same problem as Force Fed, but he obviously types faster than me.

Please explain what your car is/was doing and the cause here: Car constantly smoked all the time, was not much at first, then a little more, then got really bad after a mountain run w/ the local club, used a lot of oil. Smoke was not a thick cloud but it left a blue trail anywhere it went. Coming back from the run, I could see blue oil smoke for a couple miles behind me on the interstate lol. Car was going through 4 quarts of oil a day, at least 1 of which was getting pushed out through the PCV system into the air box, and draining out of it onto the trans and onto the ground. Anywhere I went frequently there were multiple oil trails in and out. Car was also down on power a good bit, to the point where I finally got outrun by a old Civic hatch. Which made me mad so I finally pulled the engine, upon tear down I found #4 piston was missing about an inch of ring land behind the second compression ring. No pieces found in the pan or anywhere in the engine. It had literally burnt/melted away, and it had finally burnt a small hole right through the side of the piston, allowing compression into the crankcase and oil into the cylinder.

is there blow by; no

is there oil on the plugs; a bit on #4

I noticed the car smoking after warmed up, when pulling away from a stop.
it didn't seem to smoke any other time. I did a trouble shoot on my PCV setup and found the valve was shot, I could suck and blow air through it. I replaced it with a working one, and hooked up the tube to the air box. This seemed to reduce the smoking when pulling away from a stop, but it didn't stop it completely. I pulled the plugs and did a compression test. Found a bit of oil burning on #4, compression was 145-155 across all 4 cylinders. I need to pull the oil drain back off the turbo to make sure there isn't any blockage. I'll also check the intercooler pipes to see if there is more oil than normal.

What do you mean what it was doing? It was smoking. I replaced the turbo and the smoking stopped.

Please explain what your car is/was doing and the cause here: My car would only smoke when warm. It would start a couple of seconds after stopping, there would be no smoke and then poof-smoke screen. It would go away as soon as I gave it some throttle. I pulled the down pipe and intercooler pipes and only found a little bit of oil in the compressor pipe. Then I let it run and smoke really good and started pulling plugs out. It smoked like a chimney out of number 1. I turned the motor over by hand and it stopped smoking out of 1 and started out of 3. Bad turbo. Rebuilt the turbo myself and now I have absolutely no smoke.

Please explain what your car is/was doing and the cause here: Drove the car last year never saw a hint of smoke. Swapped the factory exhaust for a full 3" with no cat. I also removed the head to remove 5 broken bolts from the turbine housing. Now once the car is hot and idling for more then 10 seconds it smokes like crazy. After reading this thread I am 99% sure in my assumption that the turbo seal is bad. I am going to try and band aid it with some thicker oil first (currently running 10W30).

If your plugs are clean, no oil in the chambers for sure, then most likely the turbo is shot, drop the dp to be sure. Thicker oil won't do squat.
