I strongly agree with you: if your argument was based on emotion/ethnic pride/prejudice, you wouldn't be opting for Japanese made gaskets: you would be a "US ONLY" guy.I ordered them on Rock Auto, but the problems aren't Rock Auto's fault. The order came from Factory Motor Parts in Concord, NC.
The Mahle valve cover gaskets for the EJ25D are now made in China instead of Japan. I feel cheated because I only paid the higher price because they still came from Japan. The job is VERY difficult on the DOHC motors, as they are wider than the SOHC versions.
It still says Japan in Mahle's catalog
Fel-Pro is Chinese now, but at least they're cheaper! Apex is even cheaper, half the price of Fel-Pro and Mahle, and they even come in a snazzy blue color, so at least they look cool
The Denso TT spark plugs were made in the US instead of Japan, but they are probably OE on some US-made Toyotas or other Japanese cars.
The NGK wires are still made in Japan
The Wagner drums aren't coated on the inside like they were supposed to be. I have a separate thread about those in the brakes section.
Sorry/not sorry: I see overseas quality control as being inconsistent. I am not going to do a job for myself, and put in all of the labor that comes with it, to have a part fail. Nor will I do a job for someone else, have a part fail prematurely, and look like an idiot.
Last year I purchased a Gates water pump, after being assured that Gates has strict quality control measures in place at their Chinese plant, only to have it fail at 30k. A buddy of mine had one blow up on him in the middle of nowhere, after a short time as well: totally different pump/engine than mine.
I see Chinese quality control as being inconsistent: there was a time that junk came out of Taiwan, but they've stepped up their game, and now that isn't the case. I'm sure China will get there at some point too.
Right now, I see them as more of a roll of the dice: more often than not you'll get quality, but sometimes not.
