I once overfilled the oil on my DRZ to the point it came out of the fill hole. Despite having changed the oil at least twice previously, I forgot it has not one, but two drain plugs. Failure to pull the other drain plug means it didnt drain even half of its oil.

Yep, I did this one once. Dumped about a quart of oil on the driveway as soon as I started up the engine.

Also I once ran a fly cutter backwards across the entire surface of a part at 3000rpm and for like half an hour afterwards couldn't figure out why it was leaving such a lovely finish. :saddowns:

Yep, did that. Had a friend forget to put the cap back on the oil filler hole. Drove to my house and had lost almost all of it in the roughly 2 minutes the engine was running.

Edit: Same friend somehow hosed up installing wiper blades on that car, too. They do fly off like in the movies!

I did that on a tractor a few years ago and it was double dumb because you can see everything you're doing on the tractor, large and in the open.

The surprise for me was, after getting a new ACVW engine (type 4 engine for my 73 bus), it had a lackluster PCV system due to the design and would spew oil out of the filler hole.

I 3D printed (!) a protype PCV and drain valve system, using an off-the-shelf valve. It worked, and a few oil changes later I accidentally forgot to put the oil cap back on before driving myself and three mates two hours south for a picnic.

Got there, checked the oil as normal (as I do after every long trip), and noticed the oil fill cap sitting next to the engine shroud. Oh no! Though I'd run my new engine dry. No mess, though, and actually mild suction down the oil fill port when the engine was running. Super happy with that.

Here's my designed oil separator/pcv system:

Worked so well as a prototype printed in nylon (would have had a few made in aluminum to sell if it worked well and I got myself a mini-CNC) that I just left it in there. A year later I sold the bus - it's still there.

WITNESS ME!



Speaking of type 4 VW engines. I had installed dual weber 40 IDFs and a mallory unilite ignition system on my 914. I couldn't for the life of me get the fucker to start. I kept turning the distributor this way and that, thinking I'd not set enough advance. Oh it had about 180° of advance because I'd swapped the order of plugs and it backfired out the carb and caught one on fire.

After I'd rectified my mistake, I still couldn't get it to start. Not for the life of me would it get going.

Turns out I had left it in gear on the stands and never noticed the starter was spinning the engine with the entire drivetrain engaged in gear. :ughh:

After that is when I found out I'd wrapped the clutch and throttle cables around each other. Every time I pushed the clutch pedal in, the revs would shoot right up. That piece of poo poo taught me so much about working on cars. Like to not leave a brake system open for a month. The 914 has a proportioning valve that must be bench bled and if air enters it, it will not leave. Man, I think I made everything I touched worse for a while there.

The PO of my present project car is the guy that bought the car and his first toolbox on the same day. That toolbox was a leatherman and a roll of electrical tape.

Luckily, I CAN go fuck myself!
At a Firestone I worked at they gave the FNG an oil change and told him to use the bulk oil dispenser to fill it with. When he was done he couldn't get the car to start because he'd let the dispenser indicator go around 5 times instead of 5 digits, so the engine had several gallons of oil instead of a little more than one.

Yes. Bonus points if this happens on your driveway and the clouds unleash a monsoon of rain after it dumped out a few quarts of oil at 10-20 PSI or whatever in a few seconds. Took 100 pounds of cat litter to clean that mess up.

I've owned mostly stick shifts. On more than one automatic, I've hosed with battery connections and fuses for 5 minutes before realizing I was trying to start it with the gear selector in D or R.

In my Jiffy Lube days, I double-gasketed an OF on a Jeep 4.0L. We did those filters from the top side and I was the hood tech. The pit guy was a dumbass, too - for the pressure check he decided to roll the sump out of the way and stand directly under the filter. I can still hear him screaming "SHUTITOFFSHUTITOFFSHUTITOFFFFFF!!!!!"

The number of times I've sold someone a low beam headlight that they said they were going to install only to have them come back confused because the light they pulled out isn't the same one is unreal. Then I walk out, pull out the lowbeam that is always tucked back in some corner and they spend the next 5 minutes watching angrily while I do it for them. :v:

Then I usually tell them about the time I spent 30 minutes trying to figure out why my headlights didn't work after changing them. I had unhooked the battery. :v:

I did something like that recently, I was starting it up to circulate the new oil but left the filler cap off and the funnel still in. The spinning clutch shot the funnel out and then misted my workbench with oil. :thumbsup:

Spent four months putting together my first motorcycle (bought as a non-runner from a barn). Got it fully repaired and running smoothly. Took it down to the mechanic to have it inspected to get a license plate. Passed the inspection. Confidently strode out to the bike, hopped on, and powerfully stomped the kick starter. Had left the bike in first gear so it jerked forwards two feet and fell over in full sight of all the mechanics.

My 99 Acura will gladly let you do whatever with the key in or out, apparently. I've started it multiple times in neutral and tried to in multiple gears.

Granted this whole car is a mechanical failure.

Hell my Dad's 96 explorer doesn't need anything at all. Just turn the ignition. It always thinks the key is in 😀

Though the steering column may randomly lock if the key is not in, fun times.

This one stumped me, my dad, and a couple friends he had brought over for their opinions as well. He had the original quadrajet on my C10 rebuilt but was never happy with it. So not long after we got it on the road, we bought the then-brand-new Edelbrock Quadrajet to replace it.

It ran even worse. It would run okay with no air cleaner whatsoever, but once you put the riser on it, it would start running like poo poo. Nobody could figure out why, so we decided to return the carb because it must be defective.

While in the car on the way to the store... I noticed a large vacuum port on the back of the carb baseplate. Nobody had checked it because the factory carb had a molded in block off, but the Edelbrock had it as a threaded open hole. Thus, a massive vacuum leak.

We still exchanged the carb.

I would later discover that the reason the old carb "never ran right" was the baseplate gasket. The Edelbrock came with a normal gasket that only exposed the venturis. The old one had a gasket that also exposed some small channels in the base plate between the secondaries.

Yeah I had a 96 Cherokee where the ignition tumblers were so worn, it would start with anything that you could fit into the keyhole. It would also let you take the key out with the car running.

I've had more than one car where the key/cylinder was so worn that I could pull it out in any position.

But thinking back on it, I know at least one of those times I was working on something on the console or dashboard and had to move the shift lever out of the way. Then I go to try to start it without putting it back into park or neutral.

e: I definitely could pull the key out anytime on my '98 Villager. More than once, I left it in reverse instead of park overnight. I use my parking brake religiously, and I did turn the ignition and lights off. I was just so dog-rear end tired getting home from work that I failed to notice that I hadn't put the column shifter all the way up.
