This past week I went to change the oil on my '88 F75 2.8TD, unfortunately after the plug was back on, the vehicle was dripping by the drain plug like crazy.
It seems someone (previous owner?) when changing the oil last time didn't have it screwed in correctly and the threads in the oil pan are ruined...
The solution the mechanic offered seems sensible - and basically involves using a thread insert kit with the differential filler plug size (larger thread than original) on the oil pan - and fitting a differential level plug instead of the engine drain plug.
Now, my questions are:
Is the engine oil drain plug fitted with a magnet? If it is the differential filler plug has no magnet, only the differential drain plug.
Should I apply a gasket/washer on the new engine oil drain plug, which is going to be a differential level plug?
What are the dimensions and material of this washer/gasket? The one I have here seems to be made of some kind of metal (aluminium?) and the dimensions I measured are:
Thickness: 1.2 mm
Inner Diameter: 17.5 mm
Outer Diameter: 25.5 mm
The differential filler plug size/thread is M18X2.5.
