GM screwed AMC over big time twice. Once with the Wankel engine that they pulled out of the deal for the Pacer. Then that oil leaking POS V6 in the Jeep. AMC tried to sue them over it but who can sue GM and and win? Good luck with that. The Jeep engine deal killed them.
I was not aware of that the but the Jeep inline 6 and their own 304/360 V8's were good engines. Some of them befell the smog regulations of the day IE leaned way out, broke/ cracked manifolds, etc, but I can't blame the engine design for that
