Your biggest DIY screwups

Discovered a wrench in the cowl under a windshield wiper, must've been left there since I last used it on the car... which was about 6 months at that point. Surprisingly the wrench didnt look that weathered, I'm still not sure how it got there.

Pity too, part of wrenching yourself is learning from your mistakes...

I just installed a nismo exhaust on my base w/sport. Y pipe to H pipe and I am short 2 gaskets and 2 bolts. The install went well, but I gotta take the muffler section off again to fit the gaskets. More like a DIY fail.

I guess i'll start.

I had to install different springs in my BC coilovers because the original ones it came with were too short and i couldn't get enough preload on them. After finishing and installing everything, i forgot to take this vice grip off. It stayed there from november until march.

no harm done, since the suspension and wheel all move as one, but it was funny to see it there.

That is hilarious.

One of my first was when I was doing an oil change on my Roadster when I was about 18 or 19. I was filling up the engine and a buddy pointed out the giant puddle growing from under the car. I learned then that the drain plug needs to go in before the refill (and to not drink beers and change oil).

This almost sounds familiar, but I'd been drinking so my memory is a little fuzzy.

Friend and I decided to put an overdrive pulley on my super-charged Mercedes. Read all the DIYs on it and thought we knew exactly what we were doing. Turns out we didn't. Ran great (extra 3 lbs. of boost) for about 200 miles and then it happened. We had pushed the woodruff key out of the slot and the pulley spun, sheared the key and drove it into the timing chain. Pulley grenaded and took out a bunch of other stuff, too. $2600 fix.

When in college, I purchased a surplus Post Office delivery jeep. Since it wasn't cool, I cut off the roof and made it into a proper jeep. Being a Business, as opposed to Engineering, major, I didn't take into account the loss of rigidity in the unibody.

After about six months, it literally broke in two while driving one day and burned to the ground.

From there, it was on to my first new car, a 1977 Datsun B210, aka "the penalty box". Kinda wished that P.O.S. had burned to the ground. It was replaced by a 1980 VW Scirocco, one of the all-time favorite cars I ever owned.

About 4 years ago on my old 240sx, I noticed that the steering responsiveness of the car had gotten pretty sloppy in the front and there was increasing amounts of body roll. Upon inpsection my father and I discovered that a sway bar bracket had broken off. We never figured out why, and ended replacing it assuming the bolts had loosened after almost 20 years of life. Then, about 3 months later I noticed the car was acting up once again and found that the same bracket was missing. This time, it had sheered itself in half with part of the bracket still bolted to the car and the other part missing. Knowing that something was wrong with the suspension, but not having the time to tear the front end apart, we crafted up a heavy duty bracket which has held up nicely.

Then about a year and a half ago, I had to replace the steering rack and bushings. Amidst doing all the replacement, I finally discovered why the sway bar bracket had been coming off. Apparently, the front right tension rod, which is held in place by three or four bolts (can't remember), had lost all but one of those bolts. That meant whenever the weight would shift to that side of the car, instead of it being properly shared, it would all shift into that single bolt and the sway bar which is what caused the bracket to sheer off. I got everything fixed pretty easily, but I was super lucky the suspension never collapsed on me in a corner.

I have a picture of the single bolt that was holding the car together somewhere and will try to post later. It has almost been cut in half.

Gurney that's epic.
