[terry (the fish ponds)]

hi all did any body have any ideas on the loss of power to my 2.5 td 98 "it runs ok but it has not got any power its like its got feul starvation
all filters and oil just been changed but no better
could it be the turbo
it was running fine one minute then went to put foot down up a hill an no power
all the best

Do you mean will not rev or will rev but not pull ??

yes it will rev fine standing still but try pulling away to over take etc it will not respond
under own steam it will still get up to top speed

That does sound turbo related,
1) Check turbo & intercooler hoses for damage (splits,loose connections,etc).

2) Check for turbo rotation...remove turbo to intercooler hose,(with fingers well clear,get an assistant to gently & progressively rev the engine),assuming rotation next with engine off & keys removed chech turbo for end float & side play.

3)Remove the intercooler hose at the manifold (get your assistant back to repeat above)with your hanh over the open hose air pressure should increase with revs,if not & the above check is OK this would indicate a blocked intercooler.

sounds to me like you could have a split fuel hose or air still in fuel system somewhere.
The 2.8 is renowned for fuel lines splitting where they come out of chasis up to tank, dont know if 2.5 is same

Also keep an eye on the colour & amount of exhaust smoke & when/if it occurs.

no smoke from exhaust at all
