Oil Change - Let down by mechanic!!

All I said was that I like youtube videos showing a job if one is available. You can get Haynes manuals with text and black and white photos, or electronic manuals with text and line drawings. If someone has done a youtube video of a procedure being done then they seem to be the best. That's all I have ever said.

I've seen some shocking how to YouTube videos.

Maybe African tools aren't too good.

Maybe but I don't work in Africa any more and the majority of tools that I use are either Snap-On or Facom, both of which are very good quality (although Snap-On are not as good as they were a few decades ago) but these still need regular maintenance and calibration.

Absolute rubbish.
All that's needed to go wrong is to set up the wrench incorrectly, misread the torque figure either on the wrench itself or in the manual or to have a faulty wrench.

Haynes Book of Lies is far from immune from errors, too. I know of one instance where the torque figure given for a banjo bolt for an oil pipe is so wrong that it's almost a guarantee of stripping the thread in the ally head.

Yes there are good and bad youtube videos.

Once any part of the tap goes beyond the end of the thread into the sump, it would be quite easy for a small bit of swarf to be left behind and with a modern close tolerance engine, a small bit of unwanted metal could do an awful lot of damage.

It won't. There's a magnet in the sump to capture ferrous particles, there's a filter on the oil pickup pipe to stop the larger stuff and there's the oil filter itself to stop the smaller stuff. You'd have to be damned unlucky for any meaningful sized damage causing bits of metal to be sucked up out of the oil in the sump and make it past the filter.

If the sump is aluminium alloy then a magnet won't be any use. I'm not saying that a small bit of swarf will cause damage, simply that it might and if taking the pan off and doing the job on a bench isn't too much of a job, It's something that I would certainly choose to do.

Just as there are good and bad mechanics and car repair places.

And good and bad forum replies.

You obviously have to use the tool correctly. You always approximate the sort of force needed before you do a job. If Haynes manual showed a figure that looked out of range you would check it elsewhere.
