andyl0183 Posted October 11, 2009 Share Posted October 11, 2009 Hi, I have a 300 TDI Disco thats seems to have no guts in it. Its fine on the flat or down hill but as soon as you show it an incline (you could even include speed bumbs!) it just cant handle it and slows right down. It has a de-cat down pipe fitted with the centre silencer removed and the EGR has also been removed and blanked off with the intercooler cleaned. Any ideas?

BogMonster Posted October 12, 2009 Share Posted October 12, 2009 Manual or auto, and standard injector pump or the EDC electronic version? Quote Link to comment Share on other sites More sharing options...
disco_al Posted October 12, 2009 Share Posted October 12, 2009 lift pump, sedimenter or fuel filter blocked. change the fuel filter first, and drain any fluids out of the sedimenter (it's under the RH rear, behind the shock bracket) Quote Link to comment Share on other sites More sharing options...
andyl0183 Posted October 12, 2009 Author Share Posted October 12, 2009 It is a manual without EDC. It has a new lift pump fitted. I will check the fuel filter. I cant find the sedimenter anywhere on the rear of the chassis would this be something that would sometimes be removed??? Quote Link to comment Share on other sites More sharing options...

BogMonster Posted October 12, 2009 Share Posted October 12, 2009 Discoverys don't always have a sedimentor so it may not be there! Quote Link to comment Share on other sites More sharing options...
andyl0183 Posted October 17, 2009 Author Share Posted October 17, 2009 Yep this disco doesnt have a sedimenter. I changed the fuek filter and no change. The lift pump is fairly new but it is a britpart and I have heard some bad stories about them so I ordered a delphi lift pump to give a bit of piece of mind. The exhaust was a home made concoction with just a back box and de-catted, it was really noisy, I have now replaced with a proper system although its still without the cat and sounds loads better. I also got a boost gauge to see what the turbo was doing. I went out this morning to fit it and noticed that the turbo had obviously been doing nothing as the actuator arm was disconected from the waste gate! I have reconected it but need to get hold of a new clip to hold it on, however I now have the power that I was expecting. Does anyone know where you can get replacement clips for the actuator arm?

sheltie50 Posted October 18, 2009 Share Posted October 18, 2009 Does the arm move, they can seize, it's just a circlip so any decent motor factor should have a box of different size's, well found! Quote Link to comment Share on other sites More sharing options...
mobyone Posted October 20, 2009 Share Posted October 20, 2009 wow, how did someone never notice that lack of power... good find mate. maybe it was diconnected for a reason too, perhaps it is trout, oils seals etc. worth keeping an eye on oil appearing around your charge cooler(bottom where it would well up), and oil level in engine, even the turbine might have awfull carp on its turbines and colour of the exhaust smoke. maybe worth checking waste gate works as it shold too... regards richard Quote Link to comment Share on other sites More sharing options...
