What causes blue smoke on a 7.3 diesel?
Blue smoke is normally burning engine oil. I would suggest checking the DP and compressor housing for oil. It's not uncommon to have a turbo leaking oil.
What causes blue smoke from a diesel engine?
Blue Smoke:
The presence of blue smoke is an indication of burning oil. Blue smoke should not be ignored but is common when starting an engine in a cold weather. The oil thins out when it is cold and some could escape into the cylinder and be burnt.

Why is my f350 blowing blue smoke?
Blowing blue smoke is oil. Oil is either coming from the cylinder or the turbo. There is no other place oil is introduced into the system. It can either be from injector o-rings, bad compression, or from a turbo seal.
What is a 7.3 Powerstroke?
7.3 Power Stroke. ... The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L). It has a 17.5:1 compression ratio, and a dry weight of approximately 920 lb (417 kg).
Can a bad turbo cause blue smoke?
If your car has a turbocharger, a blown-out turbo may be causing the blue cloud behind your car. A blown-out turbo can be identified by a broken or damaged oil seal. In this case, oil gets sucked into your engine's combustion chamber. There, oil mixes with fuel and leads to blue smoke.
Is Blue smoke bad?
While smoke from the exhaust isn't always bad, blue smoke most definitely is. How bad exactly? Blue smoke indicates your car engine is burning oil. And at the very least, there's likely a problem with the PCV (Positive Crankcase Ventilation) valve.
What does Blue smoke indicate?
Blue smoke can often look like grey smoke at first. But if you notice a distinctive bluish tint, it may signal that the engine is burning lots of oil. This could be due to worn engine components like piston rings, valve seals, or PCV (Positive Crankcase Ventilation) valves.
Can a blown head gasket cause blue smoke?
The most common sign of a blown head gasket is exhaust smoke. White smoke indicates that your car is burning coolant that is leaking into the cylinders. A similar problem is indicated by blue exhaust smoke, though this is a sign of oil leaking from the gasket.
Can a misfire cause blue smoke?
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. ... Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs.
What causes excessive blue smoke?
Blue/gray exhaust smoke means there's likely an oil leak and your engine is burning oil. ... The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.
Can fuel additives cause blue smoke?
Fuel additives like Seafoam can also cause coloured smoke because the liquid is eating away at the built up carbon in your engine leading to blue tinted smoke. If this is the case, it's not a permanent problem and after the Seafoam runs its course the blue smoke should disappear.
