Why the nozzle of your diesel vehicle keeps ‘burning’

Why the nozzle of your diesel vehicle keeps ‘burning’

1. The injector nozzles of diesel engines fail mostly either due to contaminated fuel which contains small particles that wear out the injector assembly through abrasion, or they fail due to age. An expert on LinkedIn insists that fuelling from reliable sources is the best way to prolong injector life, an obvious recommendation if there ever was one; but he also adds that tuning a diesel engine by adjusting fuel rail pressures and/or using aftermarket injection kits could lead to premature failure as well.
2. In keeping with the theme of stating the obvious, you have a braking system problem. There is a leak somewhere, which is what necessitates the daily bleeding, and much as you don’t want to hear it, the air does come from the atmosphere. It goes in where the brake fluid went out and we all know nature does not allow vacuums.

So if your brake fluid is leaking, it is replaced by air which is compressible (the opposite if hydraulic) and is the enemy of non-pneumatic braking systems. Check your entire braking system for leaks, because that is what you have: a leak. It makes your Caravan very unsafe if you continue operating as you do; one day the leak may get worse in the middle of a journey and … yeah, perish the thought.
