Its not true that SOHC cam need twice as much servicing as DOHC.
That's nonsense.
I know what's its for but can't really use the correct words. Can
someone pls help.
DOHC means two Cam, one for intake and one for exhaust valve, while
SOHC uses one cam for both intake and exhaust valve, thus generally
slower in nature.
But then, not all DOHC engines are better than SOHC one as there
are some not so good one as well.
