Ever used this for oil change?

Ours has one of those too....
But it’s a 5 min drive away.... and in this weather....

I've never serviced the 330d, so not sure if the plug is magnetic. I wouldn't have thought that it would be - it's normally just a plain sump plug that is replaced each service on most cars. I used to bye a few for my Golf.

There should be very little sludge with modern synthetics - it's normally like water and drains very quickly. As others have said, always take the car out for a 20 min drive to get the oil up to temperature, and then drop the oil soon after getting back to the workshop while all the contaminants are still in suspension. I normally allow the engine to drain for at least 10 mins to get every drop of the old oil out, before replacing the sump plug. I'm fortunate to have a workshop c/w full length pit, which makes the job easy.

 

x5, Gt, E60’s- non magnetic
OEM filter is supplied with filter o ring and brass ring for sump plug -advisable to change the brass ring (if removed)

 

Jealous? Moi??.......

 

Done the old fashion way including hot oil up the sleeve Had to use a wreaking bar to undo the filter top...25nm my arse, however sump plug was ok

 

Sounds like some 'ham fisted' bugger has overtightened it, although it will always require more effort to undo it. You're very lucky if there is no damage. Use a torque wrench to retighten to specified value.

It may of been where the plastic housing had just glued together a little as I did it hot. Cap is marked with 25NM but thanks for the info

 

In the 'real' world does anyone, especially us D-I-Yers, actually apply the torque settings for things like these? In fact, how many even own a torque wrench? I've worked on my cars over the last 50+ years and have managed fine.

Wheel bolts I can see the sense in, but other fixings etc.......?

 

I have 2 torque wrenches having been known to over tighten in the past.

 

The oil filter cap I don't use a torque wrench, if it's cracked to buggery then I know I've tightened it too much

Joking aside a torque wrench is essential for suspension components, last thing you want is a torsion rod or control arm bolt coming loose!

I always understood that torque wrenches don't work at their best at the extreme ends of the torque range. Not sure what the minimum setting is of my wrench but I'm pretty sure it wouldn't be able to give a true 25NM figure.

 

In my tool kit I have 3 different Britool torque wrenches to cover a range of 8 - 300 Nm.

I don't torque many nuts and bolts - just the crucial ones that can result in stripped treads or damage.
An example is the oil filter canister on BMW motorcycles which requires 11 Nm. If overtightened it shears the threaded attachment, making it impossible to install the filter. I've read numerous accounts of this happening on motorcycle forums.
