An engine block can twist when overheated. Combine that with torque and you can easily bend an engine block.

I always hated it when a driver would leave his pins down and dump a fully loaded AMJ into the street across from my input line. Also, pulling a full string of AMJ's through the snow never works.

My roommate saw a guy make the tiniest little aircraft strike with a belt loader. Everything had to come off the plane. ugh.

Pretty crazy considering those things fuselages are basically held together by speedtape.

The list of instantly fire-able offences at the hub are:
1.Stepping across the red line
2.Aircraft Strikes
3.Dropping a can
4.Fistfights
5.Theft

21/3/2011 - We finally did it! on the 12th of March 2011 on the 2nd qualifier for Outlaw Radial, OKE020 went 7.977 @ 178.12mph! The 60' was only 1.406 so we were pumped for maybe even a more impressive ET to follow. On the 3rd round I decided to try and run a light on a pro tree, the launch rpm was to low but the car ran an 8.20 @ 179.5mph!.

First round of racing i checked the 179.5mph data and found the engine was still in the 10.9-11.0 AFR region at the end of the pass, i pulled the tiniest bit of fuel out to play it safe, topped the fuel up and changed out the n20 bottle for a fresh one.

The car absolutely motored to half track, i am guessing maybe 2-3 mph up on ever before, about 1000ft i felt a vibration lifted slightly then put my foot down again. The stock main caps let go and the crank broke in half at over 8000rpm. I was lucky to keep the car straight and bring it to a stop. Still ran 8.30 @ 140mph The damage was pretty impressive, not much of the block survived, the rods that were attached to the front crank section were bent as it tried to leave the engine.

The engine failure can be put down to exceeding the limits of factory cast main caps. When i pulled the plugs they showed signs of detonation, not much but enough to push the already strained caps over the edge.

Still finished the day on a high. Got to thank all my family and friends for all the help over the years, we finally did it!

My job before going to work for the railroad in 1998 was rebuilding transmissions. Before I was allowed to rebuild them I did just the pulling installing part for a few years.

I did so many that I could pull or install an AXOD/AXODE in only 30 minutes. We once on a dare played a game called "name that bolt". With a blindfold on, you could hand me any bolt from the R&R out of the box and I could identify it by feel and either put it right into the car or tell you were it goes.

When I moved on to the building room I would build 2 or 3 AXOD or 4L60 trans a day. I became as intimate with their guts as I had with the pulling. I hundreds or maybe a thousand over a few years.

Inside the AXOD there are lots of ways that they can fail on their own. There is something in an AXOD AXODE and a couple other FWD ford trans called the "front planet".


That little tube bit up the center is the center shaft. It is a solid part of the planetary assembly. The sun gear when inserted down into it has a bushing that rides on the outside of it. The end of that sun gear will also ride on a thrust bearing that is down inside of that assembly which is hard to see in this picture.

The majority of AXOD variant failures are because of lube/pump, converter, clutch, or sprag failures. This usually result in the gearset needing to be replaced as they are usually destroyed. This wasn't good enough for ford. They started making a extra cut which was cleverly hidden under that thrust bearing. Just a tiny sharp cut around the radius of the base of that shaft to thin the metal to work as a breakaway perforation.

This cut is not large enough to reduce mass in any way that could be useful in fuel economy, was missing from the original front planets, and also missing from the replacement sets they sold. The break would quickly render the transmission useless and include damage to other internals.

When I first found it, I showed it to a few customers. They became so angry that I decided not to show it to anymore.

These cars with the AXOD or AXODE I was working on were rarely SHO's. They were mostly regular models with either the 3.0 or 3.8 liter V6. Those engines in the various Ford vehicles had massive head gasket issues. Some seemed to be purposefully mis-machined deck surfaces. The RMS finish of the deck surface was not just coarse, it was rippled. Looking like too fast of a pass on the machine, or a bad, dull, broken, clogged, or dirty milling tool head.

A couple times in my wheeling and dealing cars I passed on free Tauri with bad trans or head gaskets because I had such disdain for them.

That car had over 200k miles on it when we sold it, and probably lives in the woods somewhere like the Anglia in Harry Potter.

1) You're an idiot if you get under a car that is missing any parts without a jackstand. I admit, I'll crawl under from the side with just a floor jack (not the factory bullshit, see below), but as soon as there's a wheel off or other component that will allow the car to go ALL the way down? There's a jackstand under that bitch.

2) Some OEM jacks are exercises in the absurd. We dropped a brand new, $40k Mercedes in ~1987, when $40k cars were expensive. Using the factory jack on a flat, concrete garage floor.

The right rear wheel had a flat and we were changing it. Used the factory jack in the factory location. For those cars, there were holes in the side that you put a rod from the jack into, then cranked the jack up. The problem was that the jack had a 4-loving-inch wide base, which was about as stable as a Kardashian marriage. We got the wheel off, only to watch the jack slowly pivot and dump the car onto the ground. Luckily no damange, but goddamn.

What does a "jack" like that look like? Gaze upon its majesty:

From a FB group I visit. Turbo 700 trans in a Holden Kingswood decided to let go at 140km/h . The fact that the driveline basically sheared itself free scares the poo poo out of me, and I am now going to make sure I check out the diff / trans clunk on the Valiant before pushing it too hard, since I'd prefer not to have to try and steer 2 tonnes of crazy out of a skid with no power steering.

My sister's '96 Corolla recently had an A/C belt shred itself off the pulleys, I took a look at it and saw that the alternator belt wasn't far behind. Since the timing belt hadn't been touched since '06 / 70k miles I figured I'd go in there and refresh everything all at once, and I'm glad I did..



Crank pulley, shot from the passenger wheel well. Looks like something from the wreckage of the Titanic, but it's pretty standard for something that has lived in Ohio for 16 winters. (you don't wanna know about the rear wheel wells)


Hey, the pulley comes off the crank pretty easily! Wait a tick, I haven't taken the crank bolt off yet...



I've never heard of a crank pulley failing this way... at least on the VW's I've worked on. You can see evidence of the pulley "hunting" back and forth; shiny scuff on the engine block and burnt plastic on the timing belt cover. More than likely it's the cause of the belts shredding off, I'm just glad I caught this in October rather than February.

CommieGIR posted:

Those belts look....okay.

quote:

Rather than placing conventional flat gaskets between the block and cylinder heads, VW engineers instead used rubber lip style gaskets to prevent leakage where the parts joined together. What’s more, the cast iron cylinder liners stuck out beyond the decks of the aluminum block; the protruding liners then slid into recesses in the heads, and the tops of the cylinders were then sealed off with compressible metal rings. The actual combustion chambers were bowls in the tops of the pistons instead of recesses in the cylinder head; these are known as Heron type combustion chambers. Finally, the casting around the cylinder liners was mostly empty space, creating a water jacket (or one big coolant passage) around them.

If you said having combustion chambers essentially surrounded by water with multiple potential failure points sounds like a recipe for trouble, give yourself a cookie, because that was precisely the case. Not only could coolant leak out through breaches in the unorthodox head gaskets and cause overheating, but it could also slip past the compression rings and into the combustion chamber. This second, more disastrous scenario would cause anything from corrosion and misfires resulting from a little coolant leaking in to hydrolock

The worst thing GM ever did was axe the 3800. Only v6 they made that was any fun or powerful. Defenitley worth staying up on the intake gaskets/coolant. most 3100 driven cars can go drive off a tall cliff.

Hey, I finally have something to contribute!


Too bad it's my wife's car. Transmission decided to poo poo the bed without any warning. I was on the phone with her last night as she was coming home, "Hey, the car's making a kind of funny noise?" "Well, bring it home and we'll look at it and see what's up." "....I'm in an intersection and it won't go." It wouldn't go into gear at all. Cut it off, cut it back on, and she managed to get it into gear and barely get it into a parking lot. Ended up getting it towed. Shifter cable and all that checked out. Fluid looked fine, as in it had fluid and as far as we could tell in the dark it was alright.

My awesome brothers-in-law popped the pan off while I was at work. They sent me this:



1/4" chunks of metal in the bottom of the pan. $2000 to fix - 800 for the transmission, 1200 in labor. Way more than the car, a 2001 Merc Sable (with a salvage title, no less), is worth.

Looks like we'll be trying to find us a new car soon... and of course these things always happen at the most convenient of times.

I can't say that I'm sad to see it go, though. I loving hated that car ever since my stepdad first got it; once we got it after my brother got into a minor wreck which somehow caused enough body damage to total it out it became nothing but a PITA to work on. DOHC engine in the world's tiniest engine bay. Took two people an entire afternoon to replace a belt tensioner. A/C went out and that's a whole bitch and a half to replace, so we hadn't done it yet and instead swapped a bypass pulley on it. Truly a majestic POS that, while it's pretty much the worst time for it to die, I can't really say I'm sad to see it go. Other than how difficult it's going to be to get a car.

I always thought the Vulcan was a case of never going to win an award for best-engineered or great performance, but much like the venerable Jeep 4.0 has roach-like "you can run it out of oil and it will just scrape asphalt off the road and use it as lubricant instead" ability to not die.
