This turbo used to fail due to heat, or a damaged HPOP, or a failed IPR. The HPOS on the 6.0L Powerstroke engines had a different design, and the majority of the problems were caused by a bad ICP sensor placed under the turbo. Common symptoms include difficulty starting, no start, and power drain, which occur more often when the engine is heated. Then, Ford upgraded the entire design of these O-rings and introduced a new fitting to replace the traditional STC.Īnyone who still has the STC installed on his 6.0 Power Stroke Engine can expect it to fail soon if it hasn’t already. Issues with the High-Pressure Oil System (HPOS) included oil leaks produced by deteriorated O-rings induced by these high-oil temperatures and pressure. The early 6.0 Powerstroke oil injection system ran on the oil pressure, and there’s a lot of it. Here’s a detailed year by year narrative of those issues: 1. However, at the same time, users experienced different issues. All these updates brought some improvements. To complete the task, Ford used variable-geometry turbo, 4 valves system, digital fuel injection, and EGR. Ford could have followed that guideline just by adding an EGR, a clean-burning engine, and a geometry turbo to its previously made 7.3L.īut instead, Ford created an entirely new engine to satisfy 2003 federal regulations, provide more power compared to its competitors, increase fuel efficiency, and decrease engine noise. What are the Worst 6.0 Powerstroke Years and Why?įrom January 2003, the US federal government asked diesel engine vehicles to follow stricter guidelines. People have had such a lousy record that interested people are still concerned with questions like what is the best and worst years for 6.0 Powerstroke.įrequent turbo failure, issues with EGR valve and exhaustion system, clogged oil cooler are some common problems of 6.0 Powerstroke engines.Īltogether, the user experience has got tremendously bad and marked the period of 6.0 Powerstroke manufacture as the darkest time for Ford. It has acquired a negative reputation no one believes it can. The 6.0 Power Stroke Ford engine has one of the worst reputations in the entire diesel history.
