Hi. I am a vehicle Mechanic in the British Army. I have been working on a Landrover Wold for the past couple of days. The landrover will not go above 50. The original fault was lacking power and the turbo had alot of freeplay so i changed the turbo. There was metal flakes coming out of the exhaust and there was black smoke. The black smoke has now gone after cleaning out the intercooler. All that is left to do now ( i think) is compression test the engine. Does anyone have any ideas or help? Thankyou
