    Discovery 3 Engine re-build

    Started fitting crank today, piston coolers first, plastigauge quite difficult easy to smudge see journal 4 on pic, as mains caps are interference fit the tapping/levering can dislodge the bearing slightly making plastigauge inaccurate, need more practice but getting there all seem at bottom end...

    Discovery 3 Engine re-build

    Yes mate ivor Searles for machining, but saying that they are pricing me for pistons for the D4 meyle and nural, going to have the block dipped and re-bored, plucking up courage to ask for the full tour, they couldn't match price on mains and big ends. Generally now I only buy OEM quality by...

    P38A Opinion on Height Sensors

    Go for OEM electrical, had last 5 out of 6 parts a couple throwing immediate fault codes, no longer buy evilbay Chinese parts, buying used parts are ok from a trusted supplier, two out of two height sensors failed, new and its replacement, shop around for OEM can be price differences

    Discovery 3 Engine re-build

    Took crank over to ivor Searle today seems likely to be just a check and polish, turns out they agreed it is a most likely a new crank, got a bit of a lesson in main bearings kings come in grades apparently, regular bearings are called a sputter bearing, because of its manufacture I googled it...

    Discovery 4 TDV6 - shuddering engine, no acceleration/won’t rev

    Sounds like a broken crank, have one here that does just the same, would say the more you run it the more damage, doesn't always destroy block, but mostly, oem cranks are available, keeping my fingers crossed its something less serious all the best
