US Opel engines
For all the engine gurus out there, let me start this thread with a quick, general I-4 (straight-4) engine question: does anyone know of any other straight-4 crankshaft support configuration other than 3 mains, crank has paired mains for paired cylinders (M-1/2-M-3/4-M), or 5 mains, crank has paired mains for each cylinder (M-1-M-2-M-3-M-4-M)?
OK, trick question really. The Opel 1.5/1.7 OHV I-4 engine used in the Rekord PII has just 4 mains, M-1-M-2/3-M-4-M . . . like the 5 main engine except that it's missing the center main!
I don't mind admitting that this is a first for me. I didn't know this even existed until I bought my '61 Rekord PII, which happened to come with perhaps the ONLY known Rekord PII FSM existing in the US. The detail in it is astounding . . . much greater than in the later factory manuals. Engineering spec illustrations abound throughout. It's cool just owning that manual!
Another oddity is this engine's adjustable, shaft-mount rockers . . . and did anyone else know they even offered a Rekord PII Delivery Van?! Didn't know this either . . .
