Hi all..
I’m getting inconsistent power out of my manual 1hdt, non intercooled whilst towing a caravan through central Australia.
Engine, pump and injectors have done 20k since rebuild.
When we left, I struggled to maintain 90kph on flat roads.
As we went on, after two days it was comfortably managing 100kph up moderate hills.
Then it was back down to about 90kph max on flat roads, then down to 4th up the slightest of inclines/headwind.
The daily temps were all around 24deg C.
Engine water temps have stayed at approx 83deg C and Egts have been consistently around 350deg C under at 100kph many
Weight/load has been approx the same(no massive change there)
Obviously if it was a petrol engine then octane would play a part - but diesel is diesel right ?
My main thought is perhaps fuel quality ?
Or water/dirty in fuel ?
I will change the fuel filter when I get back. It’s just strange that it would get better and then crap again.
I didn’t notice a specific point where it changed. Usually the next day.
Any thoughts on what could cause this?
cheers,
Rob
