I'm in Sierra Leone where mechanics have an impressive flair for improvising with limited resources, but a lack of formal training and a cavalier attitude to long term safety.
I've had a transmission fluid leak from my gasket for a while, and have reason to believe the garage I was trying to fix it with were deliberately applying temporary fixes to give me a reason to keep coming back (a common trick here).
I've got another mechanic to look at it, who isolated the cause to a screw with worn-down threads and a worn gap, that can't make a seal and can't be replaced without cutting then welding the metal. His proposed solution was to seal it with an epoxy glue, reasoning that I'd need to cut it out if it needed removing anyway, and this way at least it's sealed.
He was insistent that this is safe and that they've done this many times before, but that doesn't necessarily mean it's safe... So I insisted on testing the (dried) glue with transmission fluid anyway. There didn't seem to be any reaction (the glue is "Teson Quick Steel", two-part, no clues as to ingredients on the packaging).
I'm sure this isn't the best solution, but is it safe, or might there be something like a slow reaction that's not immediately visible?
