My 4.6 2v is smoking, im gonna try and tackle the issue this winter i just want to know what exactly im tackling before i start picking the engine apart. The smoke is white with a blue hue, does not smoke on start up but will smoke after a few minutes of idling. No smell, smoke goes away after driving a short while and parking it up to idle, but if i let it sit idling again then the smoke comes back. When i did the oil change the oil is a consistent brown color with no milkiness and the top of the oil fill cap is not milky, new PCV valve, (<1000 miles). Slight coolant loss over the course of 1000 miles and the coolant is brown, but im pretty sure the car has not had a coolant flush in nearly a decade. Engine performance seems to be all in good shape no loss in performance that is apperant, and no compression test results, (yet). Appreciate anybody willing to help a fellow new edge owner out.

 

Colors to Watch For

Here are the main colors of smoke that you might detect coming from your vehicle, each one indicating a different potential problem:

• Blue smoke: This typically occurs when some engine oil is getting burned off. Worn or damaged piston rings can allow oil to enter the combustion chamber, creating smoke with a bluish tinge. This problem may be visible at startup but could disappear as your engine warms up.
• Black smoke: Black exhaust smoke usually occurs when there is incomplete combustion of your fuel/air mixture. This could be related to problems with the quality of your gas, engine airflow problems or issues with your spark plugs and/or ignition coils.
• White smoke: The presence of water in the combustion chamber will create a whitish exhaust. One common cause of this is a broken or blown head gasket, which allows engine coolant/water to seep into your pistons, creating a white smoke with a noticeable odor.
