  1. "Unbreakable" The model T was far from reliable, regularly snapping cranks and rods. It's simply easy to fix.

  2. This is going to require very tight clearances and very good maintenance to avoid dying.

  3.  @hairybass480  doghouse isn't just about power or engine size, it's about making sure cylinder 3 gets the same temp air as the other cylinders.

  4.  @hairybass480  fair enough, but if it's had 5 different engines there's a very real possibility that at some point in the line they went to the later style engines and their coolers.

  5. Did you at least switch it to the later style doghouse cooler?

  6.  @TheAzureNightmare  yes for the rods, but the design was fundamentally for the wrong for crank, and better rods would be heavier, exacerbating the issue. Thin, long bearings prone to oil starvation, twisting, and shearing under load. The engine used in the model a was very similar, and there's a guy who documented the process of re-engineering that one.

  7.  @TheAzureNightmare  If you look up model a engine re engineered you should be able to find the website pretty easily.

  8.  @themucleman  they're not reliable, just fixable. These things were not meant to last a long time, they're just rust resistant and repairable enough to survive as happenstance.

  9.  @themucleman  there's a balance in there, where complexity and technological advancement get very close. Technological advancement to let them make better parts more often, but insufficient complexity to make it prone to failure. In my opinion, that balance point was achieved in the late 80's to mid 90's, just before cars started to get bloated. I say this as an owner of a 1986 Volvo 240, which was almost on the edge of sufficient mechanical advancement to last a while, but was designed just a bit too early and has wonky electronic design.

  10.  @Bialy_1  To best epitomise the difference between "Reliable" and "fixable", let's look at the 90's toyota. How often does stuff break? Rarely, if ever. If it does? Well, on the side of the road you could probably do everything short of a head gasket of an engine/transmission rebuild as long as you have the right 3 sockets and a wrench. The Model T was built to be cheap, except for the choice in steel, reduce price as much as possible. "The car was known to drive and serve for many decades" yes, so is the VW beetle, there are millions of those around, but most examples have gone through at least 2 engine and a transaxle rebuild by now. Are they reliable? Hell no, but if your throttle cable snaps you can hook up a string to the carb and actuate it with your hand out the window. When I say fix, I mean fix. The trembler coils which drove the ignition were accessible by undoing a single strap, the spark plugs were massive units where you could pull out the electrode, polish it up, then shove it back in there and keep driving. A downdraught carburetor was used because it was easier than using a good carburetor gasket. Before driving you always had to pull the oil drain plug to make sure there was enough in there to keep the transmission lubricated. People had to drive backwards for enough fuel pressure to get over hills and if there was any kind of collision your seat was the gas tank and you should consider yourself Johnny Storm, because you're gonna be on fire. I won't disagree that the Model T was well designed, it absolutely was, it achieved its goals well, but well designed to meet its specific purpose doesn't mean it's reliable. It's not reliable, it wasn't built to be. Cars of that era were expensive not only because of the work that went into building it, but also the endless maintenance that had to go into making sure every day that you were in good shape to go for a drive, lubricating every joint on the car, checking the magnetos, oiling the dampers, etc. The Model T did away with that by making the car cheap enough to be disposable, and if it wasn't disposed of because it was so cheap it was cheap to buy more parts to replace where it failed.

  11.  @esra9426  by semi-modern, you mean 90's car. Thanks to finite element analysis, modern cars are safely built to fail by 100k miles in some way or another. Also, that's exactly what I said. Not reliable, just fixable.

  12.  @esra9426  Great, so there are some standouts. Generally, the cars known for lasting several hundred thousand miles were built in the 90's, such as old dodge trucks, all toyotas and hondas of the era, ford sedans, etc etc. Now a large amount of them burn oil, fry coils, have head gasket and overheating issues, transmission problems, have failed tensioners, etc etc, at a significantly higher rate than back then, amongst the noted marques.

  13.  @Null-o7j  there's a massive difference between needing 1-2 thousandth of an inch and a near perfectly smooth mirror polish with zero room for being out of round. Having some kind of moving seal to hold the pressure is very important.

  14. It looks like machining the pistons reliably would be torturous.
