Yeah, I can say the same - up to now. At least with larger engines. I've used aftermarket with all my motorcyles, tractors, small-block Chevys, etc. I've have seen lots of problems with aftermarket parts with small stuff, especially chain saws, lawn & garden, etc. We had a meeting with some reps. from Stihl chainsaw company back in the late 60s in regard to some piston failures. At the time, Stihl had been using Mahle pistons and cylinders, but tried using some Japanese pistons for awhile, and we starting having problems.
With tractors and such, 20-30 years ago we were buying M&W kits instead of OEM to rebuild engines. If anything, the parts seemed to be of better quality than OEM. Now, there are many companies offering engine parts. I've never encountered a quality problem previous to this - and with this particular case, I don't know if there IS a problem. But, for fairly new, unworn pistons, I've never seen them come apart like this. I'm not sure if I'm getting the truth from the owner about how much ether he used either. He ruined the engine the first time with ether, and I warned him about it. Said he was going to install a block heater, but he never did it.
More on the subject of Chinese parts. I've been searching for new or a good-used diesel injector tester. I ran my old OTC unit over with a crawler. I've been kind of shocked at what they're selling for either new, or used, especially on Ebay. They are fairly simple devices. Buda used to sell one made from a bottle-jack. Well, I just came across a place selling Chinese diesel injector testers for $99! Comes with adapters and is rated up to 6000 PSI. Compare that to an OTC for $700 - $1000. So, I ordered one. Seems too good to be true, but guess I find out when UPS brings it.
