I’ve never used one. I just get the Milwaukee big boy out when I want to snap the head off thingsNot sure about wappy one but I am about to do the same job if it is that tight I will be using my trustee torqu multiplier to get it out as long as I can find somewhere to lock the anchor to.
I’ve always wondered why/how someone can get a sump plug so tight, it can’t be loosened off again
I think it's called "lack of torque wrench" or knowledge of how to use one !I’ve always wondered why/how someone can get a sump plug so tight, it can’t be loosened off again

Couldn’t agree more. I very rarely use a torque wrench, but maybe being an engineer and 40 odd years of loosening and tightening nuts and bolts gives me an advantage. Folks need to learn and understand that not everything with a thread needs to have the weight of the world on it. Especially if they are going into softer alloys etc !!!Just a lack of engineering knowledge/skills
I do up a sump drain plug finger tight and with a ring spanner just ‘nip up’ to a new copper washer. Job done.
Diff drain plugs are a bit different but the skill to know when enough is enough when tightening.
Much the same when I have changed spark plugs, there is a torque setting but I never use either of my torque wrenches.
Absolutely, some of the young uns at work are terrible, a guy in a 1 year old transit, which was spewing oil from the crank."Mechanical sympathy", you can't teach it ...
I have similar sockets but the problem is that the bolt is so flat that there isn't as much "meat" as would be necessary for it to bite properly.Well now I've got to the end, may as well put my four penneth worth in.
Similar problem with my Disco'. Local garage used a socket which cuts into the bolt to hold it then a ratchet gun.
Followed by a new sump plug.
Expensive garage decoration then?!I never use either of my torque wrenches.
It could be a form of “Galling”, where surfaces bind to each other. This is more common with stainless steel fasteners though.I have similar sockets but the problem is that the bolt is so flat that there isn't as much "meat" as would be necessary for it to bite properly.
What mystifies me is that it is me who has serviced this vehicle ever since I got it in 2014 and for years this wasn't a problem, I always use a torque wrench so I have no idea why suddenly it became so impossible to undo and has led to my having to pump or syphon the oil out of the dipstick tube.
Umm, okay halfway right.Expensive garage decoration then?!
People with nothing much better to do, probably students(!) have done research on this and found out that if a torque wrench is not used people tend to overtorque small nuts and undertorque big ones, which kind of fits in with using not much different strength on the spanner or breaker bar.Umm, okay halfway right.
The 18in x 1/2in wrench was purchased way back in 1988 for when I had to refit a cylinder head following the replacement of its camshaft, since then its just used on wheel nuts, so thats just once a year with the disco… and then put back on the garage wall.
The small 3/8th wrench purchased as the disco required a full set of steering ball joints so need to torque up the taper nuts, and again when fitting a replacement water pump… in my opinion both safety critical items.
Nothing else has gone wrong so the small wrench is safe in its blue case and in a toolbox.
