My Fathers O1 PSD Has 300k on it latley especially while towing when he really needs some power it bogs down as he puts it when the turbo kicks in it bogs down what voudl couse this ?any help would be appreaciated .

 

no thoughts on this ...could it be somthing with the turbo wastegate?

 

cmon fellas spomebody has to have a thought

 

Start with the fuel filter and then air filter. Either will give those symptoms. IF they are replaced and the problem still exists have the fuel pump and injector pump checked. You failed to mention about exhaust smoke or the lack there of.

 

Filters have both been changed and there is no smoke, runs fine when not under load but pullin up a mountain cant get 30 mph out of it acts like its flooded ?

 

and i should also meantion if you step on it like to kick the turbo in it just bogs right down like its flooded

 

Does it have a Cat on it? Could be stopped up with that many miles on it.

hmm not sure if the fords have a cat i will check

 

stomp on it you should get a little black or brown smoke.

 

when he stomps on it he gets a little black smoke but no power

 

an '01 doesn't have a cat - what are boost and egt numbers? - if no gauges then look at linkage under bottom of turbo outlet - there is an exhaust backpressure device that may be stuck closed/partially closed and causing same symptoms as clogged up cat - low/no exhaust flow which is exactly what you are describing. Check the linkage to make sure it is against the hard stop, if not, you will need to replace the EBP device as it is stuck. The lever should be forward, and the rod retracted into the turbo pedestal, when you start it up cold (under 60 degrees or so) the rod extends and rotates the lever, which is attached to the plate. Also could be a symptom of low fuel pressure, but usually when the fuel pumps go they run very poor and put out a lot of white smoke.

 

Thanks for the info will check these things tomarrow ....

 

well at least it is pushing some fuel
