Typical Ken behavior.
Ask for help. Then bitch it doesnt' agree with what he thought. To top off, there isn't a single shop in the USA that is able to perform the work to his satisfaction. Yet, Ken is unable to do the work himself.
Its all about drama, "poor me", mentality.
I've given up hope this individual actually wants help. I believe he mostly wants sympathy and agreement. Doesn't really want help.
FWIW, I seriously doubt the instructors are teaching poor habits. The mechanics are learning shortcuts because of employer pressure to turn vehicles and to push more work per hour for pay incentives.
Believe as you want.
