ABSTRACT:
A number of embodiments of internal combustion engine constructions having intake manifold passages that extend from the intake ports back over the top of the engine and above the cylinder head assembly to provide a long intake passage for good low speed running. In all embodiments, an oil separator is formed in the cam cover and the engine is inclined from the vertical so as to permit clearance for the oil separator beneath the intake manifold without increasing the overall height of the engine.
