Whats the difference between SOHC versus DOHC?
S ingle O ver H ead C amshaft D ual O ver H ead C amshaft SOHC has one cam above the cylinders controlling both sets of intake and exhaust valves. While DOHC has one camshaft for intake valves and one for exhaust valves. As you can imagine it’s harder mechanically to use one camshafts to control all valves precisely.
