Well he got a lift pump and said he'd fit it bu what I think he meant was he was going to wait for me to do it for him!! Might do it tonight and when I do I'll take a look at the sender unit.

Hoping your right boycie! First thing im going to after work tomorrow is re-fit an genuine cap. At least people are thinking along te same lines here!

Also new at same time as cap and leads. But a possible. It started and ran fine just before i started work in it. Only ignition parts removed were the cap with all the leads still attached. I'm thinking the contact in the cap from king lead to arm maybe?

Tried that too. I did try it last as £90's worth of week old magnecors really shouldn't fail!! The cap's only ben on a week to, not it's not genuine lucas but really, can taking it off an re-fitting it make it die? I've got some genuine oem caps at work i'll being trying tommorrow

Right, after putting some thick oil addative crap in it it greatly improved the revving problem, so i figured it was definitely the lifters. Went out and got some rhoads lifters and adjustable pushrods (turtled i know how much a ball ache pre-load is this way makes it much easier). Fitted all...

Was just looking at that on his site, cheap considering what it does and only about £50 more than the basic one that just gives a 2 digit code and reference sheet to look it up!

Sounds like t could be fuel related, maybe pressure regulator? Try disconnecting the vaccum hose to it and see if it improves. Saying that if its temp related could be your ignition amp or coil breaking down under the temp. That could affect fuel injection timing as the neg pulse from the...

Just got a fault code of stepper motor/intake leak Now i know i don't have any intake leaks, used a fancy snap on smoke testing machine and all was well. Tried a known good stepper motor from mates range, same problems. Possible for non oem lifters to throw this code up by creating poor...

Ignition timing is set at about 8degree btdc. Runs up smoothly to being all in at about 30degree at about 3000rpm. Tried advancing an retarding to no avail.

Thanks for some good input. My thoughts were with the followers. Sometimes it will be fine till i rev it hard then it will start playing up and seeming to lack power. They don't make any nasty noises though i would have thought they would? If i go down the route of fitting genuine followers...

Always seemed to lose power at about 3k when hot. Shortly but not straight after the cam change it got worse. When cold it will happily rev to 4500rpm. It seems I be relate to the heat build up in the engine bay not the actual engine temp. Say it can sit half on the temp gauge and be fine but...

A while ago i posted about my 97 disco 3.9 v8 not revving past 3500rpm when hot. Since then it has been to 3 different garages and none of the could find any fault. I have bout and used a steve heath diagnostic tool which only once has shown code 48, stepper motor/intake air leak/ base idle...

Panard rod bushes?!

Not sure on oil level, hasn't been changed recently, just started to not rev up one day. He thinks it could be soon after he pressure washed it.

I did say it could be blocked sedimentor, is a bypass jut a case of replacing it with a bit of pipe. Any way to check injection pump? I thought the injection pump and lift pump were the same thing. Oops! The 13mm bleed banjo on the front of the pump as you look at it from the front of the car?

My friends... Yes my friends not mine 1992 disco 200tdi won't rev past roughly 2500rpm. Check the pipe from turbo to diesel pump and couldn't see and splits. Removed the pump diaphragm and again no splits. This is about as far as my knowledge on these goes so any help would be appreciated!!

No tune resistor I think will run a form of limp mode but like you say will run a more basic fuel mapping. Just put a 470ohm resistor in where your tune resistor plug is. That'll tell the ecu to run a non cat tune and properly ignore the lambda inputs

As the title suggests, how can you check and if needed set the throttle butterfly? 97 Disco 3.9v8

Start it without and it will run open loop ignoring the lambda inputs and rely on the other sensors to keep going, probably in some kind of limp mode

Cylinder head bolts lube with engine oil, water pump, crank pulley and cam bolt use thread lock. Everything else just specified torque.
