the ZETEC engine used in the 1999 ZX2 is a non-interference engine. This means that the pistons will not contact the valves when the timing belt breaks. Because of this, the valves will not be bad if the timing belt breaks
No, all Ford Escorts whether lx or zx2 are non-interference engines. Meaning that the valves won't go through the pistons if the timing belt breaks.
A broken timing belt on a Ford ZX2 will not damage the engine. The 2.0 ZETEC engine used in the ZX2 is a non-interference engine which means the pistons will not come into contact with the valves should the belt break. Because of this the valves will not be damaged and no engine damage will occur.
Maybe Ive seen it go both ways
A 1998 Ford Escort ZX2 in North America has the 2.0 litre Dual Over Head Cam four cylinder engine ( which has 16 valves )
This is true, but the Zetec engine of the zx2 has 2 overhead camshafts and 4 valves per cylinder, whereas the 98 escort lx has 1 overhead camshaft and 2 valves per cylinder. Can't be swapped. They are 2 different engines.
It has a 2.0L dual overhead cam engine with 4 valves per cylinder called the Zetec.
The ZX2 engine does not use and EGR valve. Rather it uses variable exhaust cam timing. The exhaust cam turns due to oil pressure being sent to the CVT. The exhaust valves are held open while the intake valves are open which allows the exhaust gas recirculation.
3 valves
3 valves
2 a upstream and downstream
3 or 4 valves
