Really? I'm a mechanic with over 40 years of experience. I can assure you that there are basically NO differences between modern domestic engine designs and new Japanese engine designs except for the defects in Japanese engines that are so clearly detailed in comment 12:30.
Here again, we have to look at new models, not dwell on a minor problem someone had with a 20-year-old domestic with 200,000 miles on it. All modern engine designs are very similar. Any mechanical engineer worth a nickel will agree. All modern engines are basically the same, except that in some cases domestics (such as the one I drive) have more expensive, sturdy chains (or gears in some cases) driving the overhead cams instead of flimsy rubber belts such as those used by Toyota that break every 50,000 miles and require expensive repairs.

OK, I guess I am not worth a nickel, because I do not agree with you.
And I thought not being "qualified" to make comments on this site was bad enough...
Again, you are just speculating, but providing no facts. If you have any knowledge of the subject, why don't YOU explain it instead of ASSUMING what others think?
For example, explain why so many Toyota engines are developing sludge and seizing due to improper thermodynamic design. Specifically, explain why measured data indicates temperature differentials between the head(s) and block in Toyota engines as high as 60-70, while the accepted industry design standard is between 10-15 degrees. It is known that high temperature differentials such as those in Toyota engines are known to cause sludge. If they followed proper design procedure, the problem could have been avoided.
Do you honestly still think all the accounts of Toyota engine failures on Consumer Affairs and the PARTIAL list of examples below on CarSurvey are made up?

I have just provided you with a specific design defect that has likely contributed to the many Toyota engine failures that have been occurring recently. I am still waiting for you to provide some specific facts on why Toyota engines are superior, not subjective media articles and pompous assertions that "everybody knows" (paraphrasing) your opinion is true.
I know all domestics are not perfect and I could cite you examples of domestic models with serious design flaws too. But, Toyota is no way the standard bearer for quality over domestics; they are quite the opposite in actuality. The percentage of Toyota's having SERIOUS problems (e.g., ENGINE FAILURES) far exceeds the percentage of domestics having similar problems. The only thing truly remarkable about Toyota, notwithstanding their major quality problems, is the cult following they have in light of these problems.
