The 6.0 Powerstroke is one of the most controversial ford engines in diesel history. If you’re a diesel nut, you must have heard how many positive and negative reviews it has acquired.
Users had so many mixed records with this one that new buyers still have questions about what is the best and worst years for 6.0 Powerstroke.
However, the people’s experience has gotten worse, and the market value of 6.0 Powerstroke became the darkest time for Ford.
But yes, they improved. Let’s check out these details and find out why they had gone through a worse period and when they came to the form again.
Best and Worst Years of 6.0 Powerstroke
Most of the users steer clear of the 2003-2007 models as these were the problematic years of 6.0L power stroke. They have worked on fixing the issues, but the next year new problems arose. Let me explain the overall ups and downs of 6.0 power strokes.
# Worst Years of 6.0 Powerstroke and Explained Why
To know the worst years of 6.0 Powerstroke, read the following. Hope it will also help you to understand why.
Problems Faced in 2003 with 6.0 Powerstroke
In 2003 the 6.0 Powerstroke had an oil injection function that mostly ran on oil pressure. But there arises an issue with HPOS (high-pressure oil system). The worst problem was leakage of oil at high temperature and pressure.
Then Ford upgraded this feature and launched STC fitting. But the users started having new problems like no start, having difficulties with power drain or sometimes the engine gets warm too fast.
Another major problem that was experienced in early 2003 was difficulties with ICP sensors. It was located under the turbo, which often got damaged by heat.
Failure of HPOP and IPR was also common in 6.0 Powerstroke 2003.
6.0 Powerstroke 2004
2 critical issues were found in 6.0 Powerstroke 2004. They are –
- EGR Cooler problems
- EGR Valve problems
EGR Cooler Problems
The fact is these EGR coolers cool down the gases before their reintroduction to the engine. This is what reduces NOx emissions. As a result, the temperature gets out of control, and severe gasket failures occur.
Also, when the EGR coolers fail to cool down the gas properly, it creates white smoke. This causes damage to the engine and also blocks the gaskets.
EGR Valve Problems
We know the EGR valve is used to control the number of gases that are cooled down by EGR coolers. But in the early 6.0 Powerstroke 2004, the EGR valve clogging issues were found. Their performance was poor compared to other engines. This makes the engine get hot earlier and damages the major functions.
6.0 Powerstroke 2005
In 2005 the valves were improved, but some new problems were introduced with it. They launched new functions, but the valve kept failing because of carbon buildup. This creates problems with the regulation of exhaust gas.
They started producing extreme levels of black smoke and made the experience worse for the users. It also made fluttering noises while starting and often created issues with starting the engine.
The users got very tired with this one because they had to clean the valve too much. Every time they changed the oil, they had to wash the valve, and this was a waste of time then.
6.0 Powerstroke 2006
In 2006 a new feature was added with 6.0 Powerstroke. It had a mono vane VGT which was used to minimize turbo lag. But unfortunately, this turbo changer kept failing, and severe damage issues occurred. They mostly had the same symptoms faced with a damaged EGR valve.
Another problem was that the regulating vanes started to get clogged and made blocks. This happened because of carbon buildup resulting in damage to the engine and over boost issues. It often showed no boost when the turbo changer started working suddenly.
Another problem that many users complained about is bearing failure and damage to the cylinder. This also causes harmful effects on the engine.
6.0 Powerstroke 2007
The oil cooler problem was the most common in 2007. This one works like a tiny radiator, and it keeps the main engine fuels cool and under control as it transfers heat through the engine cooler. But the problem was seen after a few uses.
When they tested the feature, it was ready to go, but the users complained that after a few use, the oil cooler stops working. The cooler gets clogged, and they block the regulator. As a result, the cooler couldn’t perform its task, and the fuel got overheated.
# Best Years of 6.0 Powerstroke
The Best Years for 6.0 Powerstroke can be found between 2005 and 2007. Because from the 2003 to 2004 period, there were no top-notch 6.0 Powerstroke models. Most of the users had to face problems with EGR and coolers, and other problems were exhausting too.
But in 2005, there was a new feature included with the 6.0 Powerstroke. They added a coil spring with it. It was placed at the engine’s front end, which started giving better rides than the previous models. Users experienced better drives with this feature in 2005, and this has continued since then.
Though people had to face problems with 6.0 Powerstroke in the 2005-2007 periods, the improvement was more noticeable. Most importantly, the problems with oil control and high pressure were slightly reduced in these years. Less damage to the engine was seen, and the probability of accidents was reduced.
Many users complained before that they have issues with starting when the engine is hot. And it performed better when the engine was cool. So, having a long drive with 6.0 Powerstroke was a nightmare at that time. But after the launch of the oil controller and EGR valves, these problems were reduced.
It is said that 6.0 Powerstroke was more user-friendly in 2006 and 2007 as users faced fewer problems and a new fitting was added. But in my overall research, the whole 2005-2007 was the worst period of 6.0 Powerstroke, but the 2005-2007 years gave some solace.
Final Words
If you are planning to get 6.0 Powerstroke, you must know what you are settling for. As you see, there has been a conflictual review on the best and worst years of 6.0 Powerstroke; you must be careful with your requirements.
Compared to others, 6.0 Powerstroke had the darkest history and improvements too. So, take your time to decide the best pick for you.
