What are the disadvantages of a DOHC engine?
About the disadvantages: more wearing parts – more expensive maintenance and repair; the risk of phase out of sync due to relaxation of the timing chain or timing belt; sensitivity to oil quality and level.
When to remove timing chain on Ford Duratec?
Ford says that when the crankshaft keyway is positioned at roughly the 11 o’clock position, the number one cylinder should be at TDC. Before you can remove the timing chain, the front cover has to come off the engine.

How is the timing of the intake camshaft adjusted?
The variable timing of the intake camshaft is accomplished through the INA camshaft adjustment system (page 11). The cylinder head cover adds support by acting as a ladder frame and does not have to be disassembled to remove the cylinder head.

How does the 2.0 liter TSI engine work?
The 2.0L TSI engine uses a hydraulic vane cell adjuster on the intake camshaft to affect valve timing. Only the intake camshaft has variably adjusted timing on this engine. Oil pressure for this task is provided by the engine oil pump. The variable camshaft adjuster provides an adjustment range of 60° crank angle.
