Sump plug?

**nadroj** · 26th August 2006, 16:14

A lot of the japa sumps have a slot in the sump plug thread for oil drainage which means they strip easily if overtightened and can't very succesfully be Helicoiled as the helicoil doesn't come into full contact and may extract it's self next time you remove the plug.
The best way is to retap the thread up to the next available thread size (commonly imperial) preferably with the sump removed. If it is attempted in place put some grease on the tap to hold onto the swarf then flush thoroughly.

Jesus this is going back,it was Heli-coiled in August 2006 a few days after this thread was started.Fwiw a torque wrench would have changed nothing,sumps on them are shite and years of regular oil changes just wore said shite out.
