Hi everyone i am about to remove my alloy 4 litre sump to fit an oil temperature sensor as there is a flat 30 mm blank on one side obviously there to accommodate a sensor & hopefully re seal the very slight drip. I am taking the advise from the forum to not use a gasket obviously checking the flatness of the alloy, I will use a gasket sealant. However one question is with the sensor most seem to come with a 1/8th thread, what size hole should I drill and what side Tap should I order & do most sensors tap straight into the sump or do they have a nut on them to fit on the inside of the sump with a sealing washer Therefore eliminating having to Tap the alloy sump (drilling it doesn't bother me) it's just Tapping it,of which i am a little apprehensive of doing but if I have to i will do. Also are digital temperature gauges any good or are analogue more accurate ?
