stobbie Posted November 30, 2008 Share Posted November 30, 2008 The problem: Defender with 200TDI engine won't rev. I don't have a rev counter, but I think it will go to max 2500RPM. If I have the car in neutral and put my foot to the floor maybe a few hundred RPM more, but with a LOT of smoke, grey but maybe even blue. Engine runs beautiful, no smoke during driving, not even at top speed. Topspeed at this moment about 60 MPH. Also no smoke during idle. Doenst use (much) oil. I have this car about a year now, and it was like this when I bought it, but I didn't care too much about it, but now I think it would be nice if it didn't have the power of a N/A anymore, but like the TDI it is. What did I do?: 1 Changed fuel filter ----> No difference 2 Changed lift pump ----> No difference 3 New aircleaner -----> No difference 4 Checked Turbo hoses ---> These are OK and not delaminating I didn't check timing and valve clearances yet, but I think the engine is running too good for problems in those areas. Any ideas? Quote Link to comment Share on other sites More sharing options...
LittleBlue88 Posted November 30, 2008 Share Posted November 30, 2008 Is this a standard Defender or did you put the 200tdi into another truck? Quote Link to comment Share on other sites More sharing options...
Jon W Posted November 30, 2008 Share Posted November 30, 2008 Check the timing, as mine had problems when the timing was out. Poor fuel economy, smoke as the timing had had moved. May be worth changing the cam belt if you don't know the history of it. Jon Quote Link to comment Share on other sites More sharing options...
smo Posted November 30, 2008 Share Posted November 30, 2008 I have similar problems on a TD5 at the moment - not a clue what's causing it yet tho Quote Link to comment Share on other sites More sharing options...
Paul Humphreys Posted November 30, 2008 Share Posted November 30, 2008 4 Checked Turbo hoses ---> These are OK and not delaminating Did you chech the pipes to/from the air filter. As this caused this to happen to my old 110. Paul Quote Link to comment Share on other sites More sharing options...
stobbie Posted November 30, 2008 Author Share Posted November 30, 2008 Did you chech the pipes to/from the air filter. As this caused this to happen to my old 110.Paul No, I didn't! Good idea, gonna check those! To the others; The tdi is from another vehicle but it is a defender one. I don't know the history of the timing belt, so I should really go change it. I thought the engine would not run as nice as it does if the timing is out. Fuel economy is good.. Quote Link to comment Share on other sites More sharing options...
JST Posted November 30, 2008 Share Posted November 30, 2008 i presume you have done the obvious and checked the pedal has the travel and theres nothing limiting the lever movement on the FIP? Quote Link to comment Share on other sites More sharing options...
western Posted November 30, 2008 Share Posted November 30, 2008 & the throttle cable has a plastic knurled nut on it for adjustment, these nuts do break off or they can slacken slightly which backs off the revs. Quote Link to comment Share on other sites More sharing options...

Any ideas? I have just had exactly the same with my 200TDi. Changed fuel filter and lift pump, no difference. The turbo hoses and air filter were changed recently anyway. I checked all the fuel lines and no visable problem, disconnected them and blew them through with an air line to find a blockage in the fuel pick up pipe. Gave them all a good clean and its been perfect since. A friend that works in a garage said he's also known a degrading rubber fuel line to cause a blockage. When the pipe breaks up on a bend you can end up with a small rubber flip inside the pipe - this then acts as a type of one way valve restricting fuel flow. matt Quote Link to comment Share on other sites More sharing options...
RangeyRover Posted December 1, 2008 Share Posted December 1, 2008 I'll share what happened with dads TD5. Might not be applicable. Catalyst collaped, blocking exhaust output, no power and wouldn't rev well. Quote Link to comment Share on other sites More sharing options...
