The joys of Injectors being under modern day common rail engines rocker covers. I wont go into the Brand of vehicle but this is what is currently happening to a lot of 1KD-FTV engines. The injector seals leak allowing combustion carbons to sneak up past the injector and into the engine oil. The issue arises when the carbon bits (nice, small and hard) get washed down into the engine's sump and sucked up onto the oil feed pickup screen.

Q: What sort of fuel economy should a 1HZ get? My 100 Series is the five-speed manual, and has front and rear steel barwork, 33in muddies and a drawer system as the only real modifications. I’m not running a winch or dual batteries either. Out on the highway the best fuel economy I’ve ever seen is about 14.5L/100km, that’s at 90km/h the whole way. I thought a diesel would be more economical than this?

How many diesels have you owned?
Australia wide there were 13.7 million petrol powered vehicles registered in accounting for 79.9% of the total vehicle fleet. In comparison there were 2.9 million diesel powered vehicles accounting for 17.2% of the fleet. Over the five year period from, the number of Passenger vehicles and Light Commercial vehicles registered with diesel fuel increased by 103.7% and 64.8% respectively.
Did you know?
In 1898 Rudolph Diesel licensed his engine to Branobel a Russian oil company interested in an engine that could consume non-distilled oil. Branobel's engineers spent four years designing a ship-mounted engine.
You know you’re in trouble when….your fuel filter looks like this!
What's this picture got to do with Diesels? Actually quite a lot.. If we're talking Turbos. Turbo chargers get quite a 'bad rap' at times about reliability yet, in reality, they are extremely reliable. The Jet engine pictured can run reliably for 20+years and it ticks over at around 10,000+RPM. By comparison a Diesel turbo installed on this Nissan, for example, can also last 20+ years but it can spin at 80,000+RPM.
Following on with some more EGT readings is one we have in . This is the peak EGT recorded from Toyota LC80 with STOCK 1HD-T engine running a 3'' exhaust ..620'C . I see something consistent happening here. Whilst we may not want to see Peak EGT figures go higher than 550'C on an After Market Turbo system.. We will see Factory Turbo Diesels running consistently at around 650'C..
Another cool Spring morning another standard EGT check. This is full load for 30-40 seconds on a Standard Toyota 1HD-FTE. Nearly identical to yesterday's Nissan TD42TDi. Going of this, one would think that 600-650'C is very normal for a peak EGT on a Stock Big Diesel. Let's check some smaller ones. Stay Tuned...
Does this image worry you? Well it shouldn't. It's the EGT (exhaust gas temperature) of a 100,00km old Nissan Patrol GU 4.2 Factory Turbo Intercooled. Yes that's 650'C and it's 7:30am on a cool 10'C morning. This goes to show that old thoughts on EGT can be flawed. It's quite common to see around 650'C plus on most factory turbo Diesels after sustained load. To be sure your Diesel is running in Tune talk to The Diesel Experts.
