Want this question answered?
The older ones, non ecotec are not overhead cam. they Use the cam in block with pushrods.
On top of the head on some cars. In the engine block on others.
No, the 4.7L is an overhead cam engine while the 5.7L is a cam in block engine.
It is an engine that has it's one and only cam shaft in the head above the valves. Instead of having it below in the block. A double overhead cam has two cams in each head.
single overhead cam Not true, it is cam in block design and over head valve (OHV).
No, this is not possible.
all the civcs have a single overhead cam motor(sohc) the civic si is the only one with a dual overhead cam motor
single ober head cam
If you change the whole engine.
SOHC--Single OverHead Cam DOHC -- Dual OverHead Cam
First of all if it is an sl1 it is not a Dual overhead cam It is a single overhead cam Either engine only has 1 t-stat
the advantage of OHC : - more accurate control of valve operation, especially at higher speeds. where as the OHV is more complicated due to the pushrod and rocker system that was added. hope this helps x
