Heads and pistons from my collection. The thing to note on the bottom head is the shim sitting on it. See the hole burnt throught it? Yeah. Did that in less than an hour, on more than one cylinder. Due to the domed piston pictured next to it.

The top one, dropped intake valve seat, ate a piston.



That looks like a VW motor, but I can't quite tell with all the fail.. How does one destroy a motor like that?

I know I an a little late to this party, but as a driveway mechanic let me say gently caress drum brakes.. I can do disks is 1/2 - 1/4th the time, the only saving grace is that they don't need to be done as often because they are in the back.

Speaking as someone from the land of salt and rust, I can say that I don't think I've ever had drums that I have bled without some rust related issue (broken valves, stuck valves, rounded / mis-sized valves from rusty buildup or wearing away, for done reason I've never had bleeder issues with rear or front disks.

I have announced to all my friends that I will only do disks as favors/ because I like them

Mechanical failure in progress at the shop. Somehow someone grounded the battery to short on the brake hardline and the master cylinder is boiling over and the lines are glowing red. On standby with the extinguishers.

How does one do that, did they try to really gently caress poo poo up?

some texas redneck posted:

That's what I was thinking. The calipers are likely fine, but the lines are already rusting, and the master cylinder and ABS pump aren't designed for that kind of heat. No telling what kind of damage was done to the electrical system, particularly with that loom that runs next to one of the lines.

Unfortunately the shop's insurance will likely take the hit, even though all they did was remove a caliper. Gonna be ugly no matter what.

edit: I sent 14" a text asking about it, apparently the car was in there for "boiling brake fluid" anyway, and followed it up with: "Haha dudes drivin it into the ground and scrapping it soon, he didn't care at all. Replaced what was necessary and he picked it up".

Then id put it on the owner.. Tell them that the system was shot and that it caused it.
Honestly I'm surprised that the abs system had that kind of power flowing through it.

Too bad the kind of catastrophic failure in that picture can't happen to them while they're blasting down the left shoulder at 130 MPH

This just happened in my area, 5 guys doing 90 past a cop nailed it to 100+ to run and 1-2 miles down the road, one broke, bounced in front of a semi, and his friend got shaken and bounced off a guardrail

How the gently caress does one let their brakes get like this? I mean on the 2nd brake job wont the shop say "time to replace rotors"?
Its obvious they dont do their own work.

Budget Monty posted:

We had a dodge minivan come into our shop that was in there only because the "Brake" light came on. It was on because of low brake fluid (Because it was all in the calipers!). Upon inspection, the rotors looked just like that, but oddly enough, the brakes seamed fine on a test drive, not so much as a pull! The metal backing plate was all that remained of the brake pad on that side, and was bent like a banana from heat. Shocking to see something that bad after virtually no noticeable drive-ability issue.

See honey I told you that if we wait long enough that noise would stop. Brake jobs are a conspiracy, I mean the parts are made of metal so there's no way that they would wear out.

jack / jackstand talk

I have had to use a scissor jack for real car work before in a pinch because my floor jack decided that it wanted to start to leak when I was working on a car and most store were closed / I didn't want to make a trip....

BUT.. it was NEVER used for support, the car went up, got dropped on jack stands (I always use 2 on the side I'm working on). I also try to put the tires under the frame of the car for just 1 more point of protection.

I've seen some terrible mechanical failures of jacks / scissor jacks.. and people who think jack stands are for pussies must think that wheelchairs or missing / prosthetic arms are super cool.

Until the rotor manufacturer states that these were not for racing applications and were not designed to take the heat / stresses of repeated high speed breaking (lame rear end Pun intended )

In good news:
At least it didn't split in 1/2 and turn into a high speed projectile

My sister had the car for a few weeks at school and mentioned some grinding from the brakes. She drove nearly 200 miles before getting home. When I got the caliper off I was rewarded with this lovely sight.

How the gently caress does a rotor get like this? Warping is usually minute, not inches of deflection. Did you cause this by laying this on a fire first?

tbf I've seen plenty of this from every age group. The problem is that 99% of American drivers are fuckwits and invent new ways of being bigger fuckwits every day.

Which is why my next new car is going to need a backup camera. Because fuckwits can't be bothered to use their mirror or crane their neck to check behind them.

Quick put It back on the car and take it to the dealer, there's a recall on that and you'll get 2 new springs, and actually I think they probably replace the whole thing because it's faster

Mine went out at 50mph almost scared my shorts brown.

I know it says pictures.. but all this easy out talk is getting me nostalgic for my most tragic "mechanic" failure

My buddy and I were doing the suspension on his car..
We ran into a stubborn bolt after completing 3 of the 4 corners in record time (probably 1.5-2hrs max) and I accidentally left him alone with tools... while I went to go get some spray and a torch (This was my bad)

He puts the socket and ratchet on it and starts trying to get the bolt out.. (even though I have a perfectly good impact wrench that we were using)
As I"m walking back next thing I hear is the loud clang of a wrench bouncing off of parts of the car (I figure he broke the bolt after the sound)..
Sure enough he says.. "I got it".. and starts turning and pulls out a little nub.

Go to sears grab some carbide bits and easy outs (Becuase I knwo that the suspension bolts on a Honda are very hard.).. I think I went through 2-3 easy outs after giving up

Because drilling out bolts is about as fun as having sex with your own grandpa while he tells you stories about how he saved .35 at the grocery store by buying dented cans, I tell my friend that it's his job to drill out the bolts (My fault again).. So he manages to not keep the drill straight.. I know this becuase after 5 min of drilling he says.. "I'm done" I put the drill through the hole and he drilled sideways through the suspension bracket...

I hate broken bolts.. and I hate easy outs.

It sounds like you should hate doing mechanical work with mechanically unskilled people, actually. Yikes.

That was part of it.. I now have a strict NO HANDS ON TOOLS policy with any of my friends that I deem mentally unfit to understand how to work on things. I've had other experiences with easy outs not working but this memory is always a PTSD onset when easy outs are mentioned.
