alot of mechanics that I know are really just not on par. they have the technical details-(secure all hoses and make sure everything is tight) aspect, but they lack true understanding of what is happening.

i got to disagree with you. most decent technicians have a much stronger understanding of how a system works, simply because they are always having to figure out why it failed. For example, if you have a transmission that is slipping, it is not enough to be able to point to the clutch or band that is smoked, as they are only the symptom of the real problem. you have to figure out what caused the failure in the first place. in order to do so, you must have a solid understanding on how and WHY the systems work the way they do. as well as having to understand how they interact with other systems within the vehicle. a heavyline technician HAS to know drivability and drivetrain, in order to understand the affects each system is having on each other, in order to correctly pinpoint the cause of an issue to the correct system.
Most auto forum members understand the basic theory behind a system, as you say the difference between OHV and OHC designs, but how many can tell you how its implemnted in the real world and why it behaves the way it does? understanding the principle theory behind a system and fully understanding the system are not the same.
