I have done my share of stupid things, I have wrecked alot of good stuff in the pursuit of repairing things over the years but thankfully I am not this dumb. I think this takes the cake.
You may remember a couple months back a Orange 71 Cutlass convertable in Minnesota. Well after probing around the engine wondering why different things didn't work I noticed the guy had hooked up an oil pressure line to the oil fill tube and abandoned it after he had no oil pressure. I had to share a pic of this.

 

Even more impressive is the amount of work he went through to get a pipe thread fitting in the oil fill tube in the first place.

 

This falls under the can't fix stupid catagory

 

That is TRUELY amazing!

 

Maybe he was a control freak and wanted to monitor the oil fill rate?

That really does take the cake!

 

He also drilled several holes into the valve covers and installed screws. I wondered why a wire was burned off the horn relay and when reinstalled it looked like an arc welder. Until I found that he had removed the red plastic insulator from the postitive post on the alternator and had it shorted on the case.
I'm hoping he removed the oil tube before drilling it out for the oil pressure switch but I really doubt it.
