Buying Used Power Stroke Diesels
Things To Look For When Buying A Used Power Stroke Diesel
"The injector O-rings have been known to be a problem. The new o-ring sets have a pink middle seal. If the truck has an o-ring problem, one of the signs can be a discoloration of the fuel in the filter bowl. There is a drain on the passenger side front of the filter bowl for draining water (the filter is also the water separator) and you can catch some of the drained fuel in a jar – it should be dingy yellow and not blue or dark. "
I am getting very little smoke and no power it shudders in the low end of the upper gears...
12 mpg highway
Here is a rundown of everything I have tryed...
Changed: fuel filter and fuel pump
Cleaned FPR screen
removed cat(rpm's fly up now, they used to struggle all the way up)still no help with power
Checked turbo...no shaft play...
diesel kleen... no help
getting enough air intake with no vacum leaks that I can feel
Fuel pressure I am getting 50-60 psi at 600 rpm(idle)and 50-70 psi at 3000 rpm
Do you guys think it is the injector rings??? How hard is it to check these???
