All engine faults/repairs/maintenance Sump plug problems

markeymagicbus: Help, 1.9DG sump plug is spinninga nd not coming oout

Wasserleaker: The engine cases are split vertically and the sump plug thread is in one half of the pair, so you cant swap the sump for a good one if the thread is knackd, like you can with an air-cooled eng. try gripping the bolt tightly with mole grips/self grip wrench and applying downward force as well as anti-clockwise [undo-ing] force and it may come out, then you'll need to rethread the hole bigger with a suitable thread cutting taper tap, and get an M16 x 1.5 renault sump plug, or helicoil insert it and re-use std. sump plug. [M14 X 1.5 MM Pitch, if i remember right.]
