Cal Posted October 13, 2006 Share Posted October 13, 2006 I feel like my disco is lacking some power at the moment - seems OK off the mark but it seems to struggle to get over 60mph or keep its speed up a slope that it used to be fine on. It's recently had new filters, one new injector, new lift pump, a good once over and the pipes from the sender unit seem OK. What else should I check? I'm thinking maybe get all injectors checked but am worried it could be something worse. Thanks Quote Link to comment Share on other sites More sharing options...
Tonk Posted October 13, 2006 Share Posted October 13, 2006 has it suddenly lost power or gradually getting worse? Quote Link to comment Share on other sites More sharing options...
Cal Posted October 13, 2006 Author Share Posted October 13, 2006 Hard to say exactly as up until the replacement injector it was running worse than normal anyway, but I would say pretty gradually. Quote Link to comment Share on other sites More sharing options...
Tonk Posted October 13, 2006 Share Posted October 13, 2006 collapsing turbo hoses? have u changed timing belt recently? if so is timing correct? leak in turbo hosing/joints? Quote Link to comment Share on other sites More sharing options...
Cal Posted October 13, 2006 Author Share Posted October 13, 2006 I will have to check them - it did have the timing belt done recently, but I did ask for that to be checked when it was in recently - I assume it was done... I've got silicon hoses so they shouldn't be collapsing, but I guess the hose from the air box could be in a bad way as I haven't checked that yet.

imspanners Posted October 13, 2006 Share Posted October 13, 2006 Has it got EGR? Try blanking it off with a plate if you have. Quote Link to comment Share on other sites More sharing options...
Cal Posted October 13, 2006 Author Share Posted October 13, 2006 Already done that... never noticed much difference, but the blue replacement hoses look cool! ;-) Quote Link to comment Share on other sites More sharing options...
Tonk Posted October 13, 2006 Share Posted October 13, 2006 is the turbo producing correct boost? check that theres no leak on the hose which opens the actuator and goes to fuel pump (boosted fuel diaphram) Quote Link to comment Share on other sites More sharing options...
Cal Posted October 13, 2006 Author Share Posted October 13, 2006 I'm not sure how to check the boost myself, but that was on my list soon anyway to get the fuelling and boost upped as have fitted an uprated intercooler. Will check those other hoses as well. Thanks Quote Link to comment Share on other sites More sharing options...
moose Posted October 13, 2006 Share Posted October 13, 2006 just my lttle bit of input, is the engine still reving ok through the gears? if not might be not enough fuel Quote Link to comment Share on other sites More sharing options...
Cal Posted October 13, 2006 Author Share Posted October 13, 2006 It seems a bit slow throught the revs in 3rd and 4th in particular. At one stage I did think there could have been air getting into the system, but if it is, I don't know where from. I was thinking of getting a new sender unit and maybe injectors to totally rule these out, but will check as much pipe work as possible before spending more money on it. Am reaching the point of getting fed up with spending more and more on it just for something else to go wrong, but guess I will have to get used to that if I want to be a landy owner! ;-) Quote Link to comment Share on other sites More sharing options...

white90 Posted October 13, 2006 Share Posted October 13, 2006 stops the engine having to breathe burnt exhaust gases Quote Link to comment Share on other sites More sharing options...
Andy Posted October 13, 2006 Share Posted October 13, 2006 the fuel pipes on top of the fueltank often rot letting air into the system. i had a similar problem a while ago, it was sand in the fuel tank. turns out the breather is nice & low & where i'd got stuck in dirty water it'd sucked loads up. sand/mud+diesel=thick goo that blocks the pickup.

JimAttrill Posted October 21, 2006 Share Posted October 21, 2006 Sounds like not enough fuel. If the vehicle has been serviced regularly it is not normally the diesel filter but the lift pump going south (slowly). Not expensive to change one luckily. Remember to either buy new unions and olives, or you can saw the pipes off the old pump and reuse the unions, but not the olives. Quote Link to comment Share on other sites More sharing options...
