Blue smoke indicates the engine is burning oil. as to how the oil is getting into the combustion chamber is the question. It could be as simple you need an Oil change. it could be as bad as the engine is worn past the mechanical ability to contain the oil in its proper ares. (Engine rebuild/ replacement required) First how long has it been since the last oil and filter change? Oil breaks down over time and becomes thin and diluted sometimes with unburnt fuel. Thin oil can get into the combustion chamber. Also you need to look at the miles on the motor. High miles means lots of wear. even lower miles could mean excessive wear depending on its history. Compression test ,dry and wet would be my first check if oil change is not needed. low dry test and a high wet test would indicate worn rings and require rebuild/ replacement. is it only at first start up? or is it all the time? lots of factors involved to give a proper diagnosis.

SOURCE: blue smoke out of exhaust, replaced turbo, still

have you driven it at least 100 miles since repair?, the oil residue builds up inside the exhaust and burns off very slowly from the previous failed turbo seal.

SOURCE: toyota mr2 roadster 2001 engine light on code po141 oxygen sens

bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know

SOURCE: I have an mr2 roadster

This could be multiple things. Could be plugs, ignition (DLI), injectors, computer, oxygen sensors, cold start sensors, etc. Complicated...worth your money to get it professionally diagnosed or you could end up replacing non-returnable parts that weren't even the problem. If you have an OBD II scanner, start there...though a simple OBD scan is unlikely to solve the mystery.

SOURCE: white smoke emitting from exhaust on diesel engine

Sounds like it might be a blown head gasket.Check for foamy cream color in oil.

I have a 5L-E toyota hilux that runs fine at idle yhen when you rev it to about 2000 rpm it starts to blow alot of white smoke. I have cut injectors out while the smoke is blowing with no noticable...


i believe the engine is running too lean as if it was running too rich it would blow black smoke If it was blue smoke it is oil related eg valve stem seals,valve guides and or piston rings all of these things will create blue smoke if one of the above is worn out

You\'ra asking about a 22 year old vehicle. I wouldn\'t take that for free & certainly not pay for it. Get something newer. Any vehicle over 12 to 14 years old, isn\'t even worth working on, unless you have decades of experience & do all your own work.
If you know nothing about cars, you need something fairly new.

Mazda 6 1.8 ts 05 constant blue white smoke out of exhaust


It probably has some internal engine damage. If you pull the spark plugs one or more will probably be oil fouled.
You may want to have a compression test done and see if you can find the source of the oil - may be a head gasket.

Blowing blue smoke on light quick acceleration on a toyota corolla 1990 after oil change oil level is normal


It sounds like your engine is burning engine oil. Depending how severe this problem may be , keep checking your oil level often. You may want to try an additive called ``NO SMOKE`` by Bardhall. It`s the only additive that actually works and the only additive I would suggest to buy. I don`t have confidence on many additives sold on shelves but I`ve used it and seen it work.

Blowing blue smoke on light quick acceleration from idle whilst stationary


Did this problem start suddenly or after an oil change or top up. Your oil level might be too high, if so the surplus will burn off. If it happens on start up or long idle periods but goes away during normal running could be valve guides or seals.

My car is blowing smoke and shuddering ef falcon


What color is the smoke ? is it bluish or is it white ?
The blue colored smoke would smell more like burning oil, which would indicate a broken piston ring, ect. the white smoke if it smells of coolant(anti-freeze) would lean toward a head gasket problem.
