Does anybody have the oil drain bolt torque conversion for 11 13 1AZ? this is for an N52 engine (06' 530). That code came from the BMW tech data cd, but I did not get the conversion. I believe it is somewhere around 25nm but I'm not sure.

25 N-m is the correct torque value.

Seems so low, that's like 18.5lb/ft? I know the oil filter cap is 25nm too...

this is silly. just put it on tight enough that it wont fall out. every bolt of course has torque specs, but debate over torque specs are better saved for things seperated by gaskets. i.e. the torque specs of the head are very important.
if you actually get under there with a torque wrench to tighten that bolt to spec, you might be the first.

Actually I was really just curious. Admittedly, I do have a tendancy to overtighten nuts and bolts from time to time, so I thought it would be nice to know what the book calls for at least until I've done this on this car a couple of times.
you'll be fine!

it is common to overtighten nuts trying to be overly cautious. get under there and just make it tight. for stuff like this i like to tighten it to a point where i am just using my wrist. dont use "elbow grease"

The spec's there for a reason - put your torque wrench on there and follow the spec. That's what any good tech will do.
Overtightening or dumping a load of oil when the bolt backs out is not my idea of fun.
