How about this then... do DCT engines suffer thrust bearing issues, or have different thrust bearings? On my car, one clutch is pushed to open like any other clutch, the other is pushed to close.
Hyundai uses 2 open clutches that are pushed closed electrically. The engine is constantly experiencing thrust when driving.
Seems that 1 second of not receiving oil during cranking isn't that big of a deal
Been years since I've seen thrust bearings worn to the point of causing issues. I have no idea what caused their demise but a betting man would put his money on skipped oil changes...
