    Fricked up a brake line and had to buy a "new" one from a junkyard

    Replaced old thermostat with a new one. Car boiled all the coolant out of the expansion tank cap during long road trip. Topped it off with a jug of water I add in the trunk. A couple of miles later it had boiled everything again. Thought I had some bad head gasket, or something along those lines, so got it towed to a shop. Got charged $300 for diagnosing the issue and replacing the new thermostat that was bad from factory. Cherry is, the old thermostat apparently worked fine, it was just caked in rust/calcium deposits, replacing it was easier than cleaning it, or so I thought. Always test new parts if you can, part manufacturers don't give a frick.

      literally none of these things are necessary, I just hand tighten oil filters so they're easy to take off. Same with drain plug, especially that.

      My real oh shit moment was stripping the drain plug on my used 2004 TL 6MT. The car runs beautifully, but whoever did the last few oil changes was a knucklehead. On my fourth oil change, it just stripped completely, no way to avoid it. Thus began a 23 hour journey to replace the drain pan, which involved dropping the exhaust and front subframe; complete nightmare. I did change my clutch, front suspension bushings and shocks, and engine/transmission mounts at the same time though, made a massive difference to the ride at over 200,000 mi. Maybe they didn't need to be replaced, but the OEM parts were cheap(-ish, except mounts and shocks).

      That said, I will never trust even a dealer monkey going forward, as this car was dealer maintained all its life.

        For next time anon, they make a kit that lets you tap it up to the next odd size, so you tap an M14 drain plug to M15 for example.

          let me rephrase: the pickup tube on this (as you may be able to see) is very close to the drain. That makes it super easy to get metal into the strainer on the tube. Best case, slight drop in oil pressure in an engine that uses a suspiciously small amount of oil for its size (4.6qts including the filter, for a 3.2L V6); worst case: scored cylinders. Also, it gave me an excuse to change many other functional but worn out components.
          It's also the opposite of a shit box, being so effortlessly performant, luxurious, and sophisticated, so it's worth it to maintain well. Not to mention the outrageously good reliability. Most OEM parts are cheap anyway.

    I put a master cylinder on a car that locked the brakes up after 3-4 stops. This was estirely unnecessary and in the spirits of 'the entire car is new so it will be a long time before i have to fix anything'

    Yes i bench bled it and its 8 replacements. No i was not converting the car to metric fittings to use a better unit. Yes i learned my lesson.

    Ive started cars in subzero to warm oil up enough to do an oil change knowing full and well i was doing more damage than a thousand dry starts.

      assuming you use a high moly oil, which is almost all of the full synthetic ones, the coating on the piston skirts and cylinder walls should protect your dry engine for a few hundred revs, even in subzero starts. You should be OK, materials science even in the early 90s was pretty damn advanced. Combine that with modern oil, it's no issue at all.

    front end is making a clunk noise, diagnose as bad struts
    this was on a 2012 ford fusion and i was following a youtube video
    did everything to a T and get to tighten the strut to the strut mount under the hood, literally the last thing, i had put the tires back on and lowered it and everything
    video says 75 ft lbs (or something ridiculous) i was in robot mode and fricking sent it, breaking off one stud from a brand new strut
    the real torque was somewhere down around 25 ft lbs
    every comment on the video is boomers yelling “do NOT TORK TO 75 FT LBS !!!111” i was just moronic and assumed that this video that’s been perfect so far would continue to be perfect
    so thats how i wasted $125 on a quick strut
    aside: it ended up being the ball joint as the source of the clunk, so i replaced the struts for no reason (they were still old tho)

    Left a rag inside the intake manifold then started the engine.

    I rebuilt the carb on my old shitbox first car one weekend. Was so proud of myself and found it much easier that I thought it was going to be. Think I was test-fitting it for some fricking reason so didn't take the rag out that was blocking the intake. Then bolted it down for real and started the engine.

    The noise was pretty bad, was pulling bits of shredded rag out through the spark plug hole for hours but the knocking didn't go away. Endeed up rebuilding the engine myself next and fricked that up too. Somehow I didn't neck myself after that saga and still have the car to this day now fully restored (by mysefl)

    Recently I was changing front main seal. Didn't want to scratch the surface. Saw some drill a hole in the seal and then pull it out. Well, the still went too far and I must have drilled out a small speck of crank material.
    I'm hoping since the amount removed was so tiny and it's very close to the center of the crank that it won't frick up the balance. I really hope not. I couldn't measure how much I knocked off. A couple sand grains amount ? Who knows. But yea, it feels bad. I hate pulling seals man.

        didn't look it up, but presumably brake fluid is designed to have specific compressibility and viscosity characteristics to prevent boiling. P/S fluid is not nearly as resilient to pressure. This will cause problems, also because the two fluids are immiscible.

    Wound up using a universal turbosmart external wastegate actuator. The original problem was the connecting rod from the actuator to the gate was slightly bent and was rubbing on the turbo stopping the wastegate from opening all the way. Have to use a boost controller now because the turbosmart operates at different vacuum than the factory actuator.

      Kek. Would have used the tiny torque wrench and it's probably the kind that bends instead of clicks. Would have moron strengthed right through it anyways.

          Probably something like this. The wrench itself flexes, while a second rod connected to the head end stays straight and points at the gauge near the handle to tell how much torque is being applied. I used one while assembling an AR-15 and it's pretty intuitive.

    I think I win,
    Intake manifold cracked on jelly bean Ford truck 2v 5.4 and it started spewing coolant everywhere. Mechanic wanted $1600 to do the intake manifold. I thought, I can do it myself. I've done oil changes and spark plugs before. A weekend of curses and swearing ensues. get the new intake manifold in there and start it up. Runs like shit. Starts blowing white smoke out the exhaust. Gonna run a compression test. Pull a spark plug and coolant starts flowing out. I found an engine on Craigslist for $800 called in my friends who knew more about cars than me and we threw in the new engine. Tore down the old one and some piece of metal that nobody has been able to identify punched a hole in the head and cracked the block. Probably my most expensive frick up to date

    about 5 or 6 years ago I replaced a VVT oil line that had a reputation for failing suddenly and killing the motor. it ran from the bottom of the motor all the way up to the rear bank. took about an hour and a half all told to get it in place, go to turn on my car and oil sprays everywhere making a huge mess.
    I prayed it wasn't the bottom bolt which was a pain to get to, and it actually was the top one. felt like a huge idiot but tightened it up and never had an issue.

    I was 18-19 years old living with my aunt and uncle in California working on my 07 Nissan Frontier replacing the water pump. I was being a lazy piece of shit and I wanted to go out with friends instead so I let my uncle finish working on the water pump. The next day I was driving my car and overheated so badly that I lost compression in the engine totalling the truck. Turned out my uncle never put the gasket in the water pump. Never ever let anyone "help" work on my vehicles without me there or it being in the shop again.

    While working on cars often runs in a family, individual execution styles can differ wildly. That was the case for my father and me. He was a "get it done" auto mechanic while I'm an engineer and tend to be more thoughtful and detail oriented.

    One day I was in the driveway changing the brakes on my car. The front rotors were, of course, seized to the hub, and I was working to get them off. After spending some time trying different things, I noticed that these particular rotors had threaded "jacking" holes that would accept a screw which could be used to separate the rotor from hub. So off I went in search of metric screws to fit the holes.

    In the meantime, Dad was sitting on the porch drinking his coffee and watching me struggle. After a bit he asks "Got new rotors?", to which I replied "Yes." A couple minutes later he gets up, goes to the basement and comes back with a sledgehammer. He walks up to the car, takes a single swing, and pops the rotor off. Without a word spoken, he returns the sledgehammer to the basement, then resumes drinking his coffee.

    I look at him, scrunch my face, and say "Yeah, I guess that works too!"

    To this day, every time I find myself struggling with a problem I think of him and smile!

    Many years ago, I had a VW Transporter van with a rear 1.6 liter inline-four, water cooled diesel engine. I took it on a long vacation to the mountains with a couple of my buddies. Going uphill on a long steep grade, it started overheating. After stopping, I noticed a coolant leak. It was coming from the hose clamp on one of the hoses spanning the length of the van, from the engine in the rear to the heater core in front. I fixed the leak, but realized I had no coolant available or place to buy it anywhere nearby. I decided to fill up with water from the mountain stream flowing through the rocks. I was amazed how much water this car needed. For such a small engine, it had a huge radiator and four large hoses going from back to front, providing heat to the cabin and running to the radiator. The rest of the trip was uneventful, but once home, I immediately replaced the water with fresh coolant.

    On my first drive afterwards, the van overheated. I figured that the stream water had destroyed the water pump impeller or plugged the radiator somehow. I checked the cooling system piece by piece. I could not find anything obviously wrong. I made sure that there was no air pocket trapped in the coolant. I checked belts, pump, thermostat...all looked OK. I was about to pull the radiator from the car when I realized my mistake.

    To remove all water from the system, I had disconnected the lower radiator hose and pulled it from its normal position to below the front frame rail, letting out the water into the drain pan. What I did not realize was that when reinstalling the hose, I had forgotten to place it above the frame rail. Reinstalling the spare tire in its place, behind the front bumper (underneath the van), had pinched the hose to the frame rail almost completely cutting the flow of coolant. Once I rerouted the hose like it should be, the VW ran with the coolant gauge needle sitting right in the middle; no more overheating.

    not really personally my maintenance frickup, but I was personally moronic about it.

    bought a brand new to me car from the dealer, good condition, ran great, excellent price. gtg. fast forward about a week I'm cruising down the freeway when suddenly I hear a noise. I can't really describe it, but it kind of sounded like a quick release of air like if you got a serious puncture on your tire, however it only lasted about a second and was just loud enough to hear, so I knew it wasn't that. a couple of seconds after the noise I get the charging light on my dash. I thought God damn it, did the alternator go out? thinking I was now running on battery alone I decided to keep driving to try to make it home before it went flat. soon after I noticed the temperature creep up and again I figured it was a symptom of the battery draining causing an electrical gremlin so I ignored it and kept driving. maybe about 3 minutes later the dash started dinging at me and the display was telling me the engine was overheating. i was off the freeway at this point so I said frick I should probably pull over and at least look. I did just that and lo and behold My serpentine belt had turned into spaghetti and wrapped itself around the crank pulley. well... that explains that. I let the engine sit for a while so the fans could cool off the radiator and eventually it was cool enough that I can make it the rest of the way home which luckily was only a few miles away. I took the other car to the parts store for a new belt, slapped it on and it's been running perfect ever since years later. got super lucky my dumbass didn't blow a head gasket or warp the block or anything from being stupid and not reading the symptoms correctly.

    and before someone says something about power steering, yes that absolutely would have been a dead giveaway... if the car didn't have EPS.

        Motivation is the hardest part to come by sometimes. I find it helps to just go out and do something in the shed, even if it's not related. Or even something related but very simple/menial. Are all those bolts/mounting hardware clean? Go wire brush all the threads or something. Build from that, snowballs until you're elbow deep in the engine bay with the engine swinging off the crane.

    Back in the mid-90s, when I was a full-time mechanic, I prided myself in troubleshooting driveability problems, check engine lights, emissions failures and such. That became my primary role in the shop. Instead of spending most of my day spinning wrenches, I was typically armed with an OBD scanner or DVOM. So when a customer came in with a sweet little 1966 Mustang (a recently purchased retirement gift to herself), complaining of poor gas mileage and lackluster performance, it seemed like a break from the doldrums of checking engine codes and a return to a time when things were simpler...or so I thought.

    She dropped the car off, and I took pleasure in driving it a number of times to replicate her issue, except that I could not; it always ran great. But when I pulled the spark plugs, they were pretty sooty, but would clear up after I drove it a few times. I hated to waste her money replacing parts, but every few weeks she would be back with the same complaint. I even drove the car home a few times and calculated the gas mileage, which at about 15 MPG, seemed reasonable for a V8 with a 4bbl and no overdrive. I ended up rebuilding the carburetor, adjusting valves, replacing points and condenser, etc... and the problem continued, except I had never experienced it.

    Finally, I asked her to take me for a ride so I could pinpoint the exact moment she experienced the issues. Well, it took less than a minute to realize the problem. When she got in the car, the first thing she did was pull out the handle for the manual choke and hang her purse on it. Then I understood why she said it ran fine at first, then worse the farther she drove. The word “choke” had worn off the handle over the years and she mistakenly thought it was the fresh air vent. At her request, I put a new choke cable on it, and we laughed about it whenever she came in for work on one of her other cars.

    While replacing the thermostat on my old 1991 Ford F150 Lariat, I got the cover housing all cleaned up and ready for the new gasket (which had some handy adhesive on one side, how convenient). Well, I set the gasket to the side, and seconds later, it was nowhere to be found. I tore that garage apart looking for that gasket.

    After hearing plenty of not so nice words coming from the garage, my wife asked me what was wrong. I told her about the gasket in a very heated way, with arms and hands flailing. She immediately started laughing like crazy, and boy was I mad! She kept pointing at my elbow but was laughing too hard to speak. The gasket was stuck to my left elbow! At least I found the dang thing.

      That’s the same dumbass who overfilled the oil on this old SL500 he got, decided he would try to loosen the drain plug in the street to let out a quart or two onto the asphalt, and all of it, which that V8 probably holds a lot of oil plus the quart or more extra, dumped into the street and ate away at the asphalt and left a pothole

    My first time doing real work on my own car I was doing my front brakes. The passenger side went well, and with more confidence in what I was doing, I moved on to the driver side.

          I’ve done it too. When those soft bleeders have been salted in there for 10 years, I don’t think there’s much of a chance. And you can’t really torch the frick out of calipers… or maybe you can but it was easier to spend $80 on a pair of rebuilt calipers
