M12x1.25 thread

[Trojaneagle]

My oil pan has a 12x1.24 plug on the side of it well above the oil line. Can I use this as a drain port? where can I find a fitting with a hose end for that size thread?

BB Turbo maybe but it's a bit small and low to be effective.

Do you think there is a problem of it backing up into the turbo?
It's not BB.

Non BB yes as they flow quite a bit of oil (BB has a pair of 1mm restrictors to limit flow)

yeah its too small for a turbo drain. i always run a -10 size drain. the fitting you are talking about is closer to a -6 size.

shame that the oil coolant return is below the oil line. That is a big 16mm sucker there!

-10 is considered to be the standard for the turbo drain. (at least on our cars, but i'm not sure why you'd go smaller on anything else either).

you could cut out the oilpan threads with a hole saw (of course, with the pan removed so you don't get all kinds of metal shavings in your pan), and weld on a -10 bung.

Think my GroupA Pan came with -12 fittings so that's what I used but usually I use around -8>-10 on BB turbos.
