hi the 4.0l does not have carbs but yes could be a mixture or fuel pressure prob thanks.

Hi all please help, I have a 4.0l disco v8 1999 has been running fine then suddenly after a short stop it lost power and miss fires, cut a long storey short, when parked runs fine when under load has no power and misfires. I have changed the coil packs, leads, plugs, fuel pump, and mass air flow...

Hi have today ordered a new short block as no one can quite put there finger on the problem. We have narrowed it down to oil in the bores, and yes have checked liners, oil wiper rings etc.

Thanks for reply since i bought it i have run about 3 galons of fuel through it but it has a tiny fuel tank as lpg tanks under, so fuel pritty much replaced, i fit oil boilers for a living a i put my gas analizer in exaust readings of over 5000 ppm (co2) no o2 dont know if this points to any...

Hi all I have now flushed the engine blocked off the brake servo and dis-connected the down pipes to prove the cats are not blocked/full of oil. And still it smokes but the confusing bit is that i was expecting one bank to be the cause, its both banks of cylinders smoking ????

all stem seals changed and pushed on firm dont know where the breather are on v8 norm play with 300tdi and td5 if i remove the filler cap there is no pressure there at all if i pull the rocker cover pipe to inlet man no change it also runs as sweet as a nut and boy does it go ? thanks

Hi heads are good. thanks

Hi can any one give me some idea of what i have done wrong, I have just bought a disco 4.0l v8 with lpg kit that smokes, pressure tested engine and had 130ps per cylinder and with a drop of oil in each 150ps. So i striped it as i removed the heads i saw that there were 5 valve stem oil seals...
