OIL PICK UP
Tip: Clean the oil pick up in the sump before it kills your engine.
The pic below shows what can happen when the engine oil gets polluted with diesel when repeated DPF regen cycles have occurred over a long period of time.
It can also happen if you use the wrong engine oil.
Check and clean it every 80 – 100 thousand kilometers.
If the oil pick up is blocked it will starve the engine of lubrication and destroy your engine.
This is a nice new one.
