Dear Experts,
I want to discuss the reasons why would a Diesel engine Smoke on Cold Start Up ?
What could be the Reasons ?
- Incorrect timing
- Dirty or worn injectors
- Over-fuelling
- Faulty turbocharger (ie not enough air to match the fuel)
- Incorrect valve clearance
- Incorrect air/fuel ratio
- Low cylinder compression (eg sticking piston rings or worn components)
- Dirty air cleaner
- Restricted induction system (eg system too small or kinked inlet piping)
- Poor quality fuel
- Excessive carbon build up in combustion and exhaust spaces
- Cool operating temperatures
- Worn valve guides or seals
- Wear in power assemblies (ie cylinders, piston rings, ring grooves)
- Cylinder glaze
- Piston ring sticking
- Incorrect grade of oil (eg oil too thin, and migrating past the rings)
- Fuel dilution in the oil (oil thinned out with diesel)
- Faulty or damaged injectors
- Incorrect injection timing
I do understand another big tell tell sign in diagnostics is the color of the smoke Aswell like WHITE - BLUE or BLACK
I had heard that my LC was smoking on cold start so had a Video Made of the Smoke and wanted to get an Expert Opinion.
