On repairs.....visual appearance is a big part of it. You just slap new parts on, looks bad, customer doesn't trust the work.
Worked the line at a dealership for six months once.
Timing chain? Clean and paint the timing cover.
Water pump? Paint to match. Valve cover gaskets? Same.
One of the staunch Union pukes in the shop decided I was making them look bad, so while valve covers were drying on the back of my workbench (and I was over drawing new gaskets), he shook floor sweep all over the wet paint.
On the video.....seen that stuff before, but look close.
The two former employees had a beef over wages with the owner, and admitted to doing just what they were reporting.
Takes the focus away from the owner somewhat when employees did it, admitted it, then narc'd out the shop.
Stuff like that other shops should remember...figure out who the numbskulls were, and never hire them.
Then there are the clueless. Talk a good talk, seem to be able to perform the tasks required in the work order....but really have issues.
Worked with a guy once who could never get timing gears, chains, or belts right first time. Sometimes second.
Another who professed high skill levels in GM Auto Trans....did some kind of valve body performance kit from underneath...somehow got the check balls on the wrong side and broke the case.
The Mercedes, though.....front brakes. Turn the rotors, new pads, repack the bearings...and somehow one of the big metric bolts holding the caliper bracket to the spindle he lost.
Didn't say anything, nobody knew...stuck and SAE bolt in the hole....threads didn't even touch.
Came back on a hook with one wheel locked, caliper kicked out against the wheel.
Or the 195o Mercury Pickup for a clutch. Moron worker put the throwout bearing and hub in backwards. First I knew, he called me over because he couldn't adjust the clutch.
Showed him the error of his ways, he pulled the trans, put it back, still a problem...and he put it in backwards the second time.
Good thing he never tried to start it.
You can't watch them on every function.
Boy, I'm glad I am out of that.
