A reconditioned head is no different to a new one if done properly. I would go recon with a decent supplier. Its not false economy, false economy would be fitting a second hand untested head.

They are right fiddly to fit, and I took ages getting it back together becuase I forgot which rods fit which arms etc. Taking pics is a good idea. There are guides on here, its not difficult just fiddly. And give it a good shot of a decent sticky grease like HD ultra before refitting.

Its not risky at all, the expansion tank water level goes down not up. You blow into the tank, if you suck air out your don't get the desired effect.

look on a well known online auction site, search for discovery 1 lock springs

Just fixed mine, same problem, turned out to be broken springs (get them off the net cheap) and needed a good greasing up.

I recently changed the thermostat and water pump on my 300 disco auto after discovering the bottom end rumble noise was in fact a failed water pump bearing. After changing both, I could not get the engine to bleed up, specifically, no heat from the heater unless you rag the engine! Disaster...

You will need a diagnostic to determine which sensor is causing the issue as it doesn't sound mechanical.

If its an auto, I assume it still has the edc pump? If thats the case then there is no adjustment on the pump other than refining IQ.

I can explain the tuning and similar boxes very easily. These boxes all work the same, the basic principle is the EVRY mod used to fool the pump into supplying more fuel by either (depending how its wired up) telling the ecu the fuel is cold (more pumping force needed) or that the fuel supply...

good on you

Slightly off topic to the OP but you get the drift, 21mpg is a bit low so deff' a problem some where.

I think I am getting 27mpg average. Based on mixed driving. I bought it doing 24mpg with the decat and egr delete. I gave the auto box a full service, pumped the tyres to the correct pressure and dumped a cheap fuel cleaner through it and that has brought it up to 27mpg average. I think with a...

Check the fuel supply. Can't check anything else until that is ok'd. Fuel starvation won't throw up any codes.

I think you can test the lift pump, I saw a guide on here somewhere, they are dirt cheap to buy and so easy to fit.

The trouble is, traders hide behind rough sounding, slightly smokey diesels as it being (characteristic old diesel stuff)....... "its done 200 million miles but its normal to be under powered and smoke a lot" Its complete rubbish, I regularly see polish cars (older diesel tech like the 300/200...

Chip will be here soon. Then pics. I am expecting to see 135bhp without reseting boost pressure, 145 with boost pressure, and 145-150bhp with a large intercooler. This is just guesstimating at the mo based on similar engines etc, I will run a few dyno tests soon.

I get 485 miles from 1st click to light on. Mixed driving.

Lack of fuel makes a huge difference to mpg. If the pump is working harder to draw fuel, it will take longer to prime up each stroke to supply each injector, when the pressure is finally reached, it triggers the injector break pressure too late, causing incorrect timing, and as the stroke...

lack of fuel pulls back the timing which will make a diesel very very sluggish but not smoke so much. Proper diesel diagnostics dictate you start by making sure there is sufficient fuel supply. Confirm this first, then we can work through the sensors :)

ah yes sorry i thought you had a manual pump conversion. I would look at the maf sensor next. and the lift pump
