They are non-interference engines. Though I have known people with the 1.8 lumps to have bent valves when the timing belt / tensioners gave way. Mind you, the 2.0 has a lower compression ratio, so the valves sit further away.

Are Ford Zetec engines interference?
The Zetec IS an interference engine, give that regular pistons will hit the valves. However, the Zetec ACTS as a freewheeling engine, given that Ford put recessed pistons in the engine to give the valves clearance to be fully extended and the crank can turn without the cams without damage to the pistons or valves.
How do I know if my engine is interference or non-interference?
The difference between an interference and non-interference engine is whether there is a gap between the valve that is fully open and the piston that is in the top position. If there is a gap, the engine is called a non-interference engine. If there is no gap, it is an interference engine.
Is Ford 4.0 an interference engine?
Fortunately, the 4.0L SOHC is not an interference engine so a timing chain failure won’t bend the valves. … This timing chain cassette can be replaced without having to pull the engine out of the vehicle.
Is a 2008 Ford Focus a interference engine?
yes your engine is non interference but if your timing belt breaks it will still bend your valves because the valves will hit each other.
Are Zetec engines good?
The Zetec engine is very reliable; with normal care, it will probably take you to 200K miles and beyond.
Does a 2003 Ford Focus have a timing belt or chain?
If You’re wondering whether the 2003 Ford Focus has a timing belt or a timing chain, You’ve arrived at Your destination. The Ford Focus for this year comes equipped with a timing belt.
What makes an engine non-interference?
Put simply, in a non-interference engine, when the piston is at top dead center (TDC), it will never go higher than a fully open valve; that is, the piston can never “interfere” with the valves. Conversely, in an interference engine, the piston could occupy the same space as an open valve.
Is the Ford 1.6 EcoBoost an interference engine?
1) Ford 1.6 EcoBoost Timing Belt
Timing belts on the 1.6 inline-4 turbo engine don’t really seem like an issue at all. However, the Ford EcoBoost is an interference engine. This means there is some overlap in the area the pistons and valves travel.
Is the Ford 3.5 EcoBoost an interference engine?
It’s an interference engine. Usually a good tech will use a borescope to look in the cylinders to see if there are any signs of if valve contact on the pistons. If no signs of contact a compression test can then be done.
Is a Ford Ranger an interference engine?
2019 Ford Ranger – Timing Belt Or Chain
All 2019 Ford Ranger engines have a timing chain and are interference.
Are all Ford 4.0 engines the same?
Tech By Trade said: Any 4.0l SOHC will fit, you just need to strip it to a long block, and swap all the components over to the replacement 4.0L SOHC. The Block heads, and pans are all the same, just the window dressing is different.
What is an interference fit engine?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
