Where is the timing chain located in an overhead cam engine?
In overhead cam (OHC) engines, the camshaft is located high in the cylinder head far from the crankshaft. This requires a much longer chain or a rubber belt to drive the camshaft. In some engines, such as a Chevy 3.4L DOHC V6, a timing chain is used to drive an intermediate sprocket that drives two belts (one for each cam).
Where does the timing chain go on a pushrod engine?
As a rule, most pushrod engines use a timing chain to drive the camshaft, though some older four and six cylinder engines use a gear set. A short chain or gear set works well in this kind of application because the camshaft is located in the block just above the crankshaft.
