smoke screen... of death
Before whenever I went over 3500 rpms or so ALOT of white smoke would come out of the exhaust, and gas mileage sucked bad when I took it up there. Now it wont even go past 3800 and smokes. Still terrible mileage. Here is a pic of what the smoke does to the exhaust...

black smoke is excess fuel and would leave black sooty carbon in the tailpipe, i don't see any layers in yours so i am going to say more than likely the cloud is either oil burning off due to failed oil seals which are fouling the plugs or a coolant seal issue and the cloud is coolant burning which is more likely since there is condensation in the exhaust in that picture.
now keep in mind it could still be none of those cases i mentioned, during winter some mixtures when cold can just produce large amounts of normal condensation from your exhaust. water is a normal byproduct of combustion, if the cloud goes away after the engine is warm then you have a different problem. you could have many problems but warm the engine first and see if it still lacks power. some things to note: some thin white smoke on a cold engine is normal thick white smoke on startup in the middle of a warm day is not normal - coolant in engine any type of light blue hazey smoke is oil burning black or grey smoke is fuel, indicating a severely rich condition and will leave black soot in the exhaust |
notice any severe drop in your coolant level?
on cold start if you pull the cap off the overflow bottle, is coolant PISSING into it? |
Nope, coolant hasnt gone down at all. There is a lack of power especially at higher rpms.
It has a pretty bad smell to it too. The oil does drop alittle faster than it should, but I have a leaky pan so I think that is the problem. Im positive it is white, but Im not losing coolant. What gives? Tommorrow I will try to get a pic of the smoke pouring out while im driving. |
I had the same thing going on with my car. I fixed the timing and started using 20w50 and it all but went away. Just a thought.

I see only 2 fluids there :) To my knowlege, it's what karack describes. Pretty common knowledge. |

^That's what I meant :) I was just saying that three things have been mentioned and the poster ruled out two...
|
i wouldn't consider them ruled out, though i doubt it is coolant, it takes a bit more coolant than it does oil to create plumes of smoke.

how many k's on this engine?

time for a rebuilt
