I just read part of the original post and would like to point out that the EAO engine had nothing in common with the Lima engines. The EAO 2.0 was typical of German engineering- it still had solid lifters in the 70's when everything else used hydraulics and was prone to failures. The oil pump relief valves would stick and blow the head gasket under the carb area, so we had to pull the head, raise the engine, and replace the pump, all before replacing the head gasket. The cams were prone to failure, a cam change on a LIma 2.0, 2.3, 2.5 is a minor job because the cam slid out the front. Not so on the EAO 2.0, the cam came out the back so the head had to come off first. If Rube Goldberg designed the 4.0 SOHC cam drive, his father designed the EAO 2.0. Given a choice on a pre-Lima Pinto, I would opt for the oil leaking, underpowered Kent 1.6 over the EAO.
