Ummm, I am scared to post anything.
I am probably the source of most of these stories. I had no gearhead mentors growing up, my parents would not open the hood of a car. So I had to figure out a lot of easy things the very stupid way. I'm no better now, but the stuff I have to rely on goes to a real mechanic.
I had a Porcshe 924 in Germany, and the main harness was developing a short. First the headlights went, the the motors to raise them, then the ignition. Being mostly volkswagen, the fuel pump relay had already gone. Then they really bitchin steering hwwel I pulled out of a junkyard car that didn't clear the turn signal switch, so I notched the stalk, which was great until it broke, the next day.
My solution to each of these problems was stereo wire and a $.50 rocker switch. By the time I passed it on to the next guy, starting the car required the activation of three seperate swtiches along with the key, as well as another 2 to operate the lights, and another 2 you had to turn on and off to make the signals flash. There was no ryhme or reason to where they went, I just cut a hole in the dash, or the console and mounted them without a label.
81 Scirocco, water pump went bad. Cut the timing belt cover off with a dremel tool, cut the timing belt off. Realized I couldn't pull the water pump without pulling the crank pulley, took it to a mechanic. He tried to tell me in broken english (It was also in Germany) as politely as he could something along the lines of the hood lock lesson mentioned earlier.
Same car, caliper freezes up, I sucess fully remove and rebuild the caliper, put back on, back out of driveway when I realized why I would need to bleed the brakes. Luckily hit nothing. Resolve that with the car in the street, pull forward car locks up, forgot to put in the top caliper bolt. The caliper has tilted forward and jammed against the inside of the wheel. reverse back into the garage, fix that. Back out for a test drive, find the largest hill I have, scream down it at 90, jam the brakes as hard as I can to "test" them....
..luckily I had actually fixed it.
1991 GTI, I was given a set of steelies with snow tires. They didn't fit over the center hubs, so I "forced" them on with an impact gun. Whel I pulled them off with a hammer in the spring, it was a month before I realized what the whumping sound was and why the wheel steering shook when I let off the throttle. I had stripped every lug hole on the car.
Same GTI, given a "Cold Air" intake. Looking to mount it, I disconnect the "emmisions crap" box between the airbox and intake. When the car wouldn't start I then diassembled my air flow meter still thinking it was emissions to make it fit on the filter. That was a pricey replacement.
Blew a rotar in my 2nd Gen RX7, became conviced the problem was the catalitic converter, hacked it off, hit it with a BFscrewdriver and mallet util I cleared it all out, welded back in place. Still no power....
Guilty of a lot of stereo and fog light installs all using the same speaker wire, as well as the "twist, tape, zip tie" method of wiring
