And no, I'm not quite a newbie. Two clutches, three cylinder head rebuilds, drive shaft rebuild, countless brake pads, three exhaust systems, a starter and a fuel pump later I think my hands have earned the distinction of "Weekend Mechanic of Merit". The engine and drive system is easy 'cause like you said it's the same stuff in different shapes and sizes across all drive trains. My peeve is all the equipment attached to the fenderwalls and firewalls with wires and pneumatic tubing running every which way and absolutely no description of what it is or what function it's supposed to be performing. I mean I bought this baby new and it's got 405,000 miles on it. How much more time do I have to find out what everything does?
