No, not entirely, at least not in my experience. I’ve replaced three engines in the past ~15 years. The first was caused by a head bolt over-torqued from the factory, which led to a non-visible gasket failure and ultimately coolant making its way into the cylinders and destroying the block. The second was a failed pistol skirt. The third seized due to a manufacturing defect in a cam bearing. All of those problems would have been cheaper and easier to fix in a 1980s-era vehicle. The oldest of these was a 2000, though, and it was cheaper to replace the entire engine than it would have been to buy the parts to repair them. That doesn’t even include labor - and the labor required for many things these days is much higher than it once was.
