Stripped Engine Block

This is the internal combustion engine block stripped to the casting, crank, rods and pistons. The short block is all aluminum with steel cylinder sleeves. The timing chain guides are made from plastic with a robust aluminum backing. Looks like Honda will avoid all the timing chain troubles motors that the Toyota 22RE encountered. The reluctor for the crankshaft position sensor is mounted behind the lower timing chain sprocket, and the sensor is mounted in the side of the oil pan. The main bearing caps are webbed together for added rigidity. The casting quality is excellent. It’s very smooth, even in inaccessible areas, and there is no porosity evident. Honda did have some trouble with porosity on the J35A V6 motor, but I doubt this casting will ever have trouble. The quality really is very impressive.
