Do some models of Suzuki are not affected when timing chain/belt break?

Question

I've heard that some models of Suzuki trucks/car are immune to timing chain/belt break. Has anyone know if this is actually the case?

Answer 1

I don't think any engines by any manufacturer are immune to timing belt / chain breakage. What you have heard is probably that if the belt does break it will not cause damage to the cylinder head, pistons and valves.
On many engines, there is little clearance between the piston top and valves when the piston is at the top of its stroke. If the cam-drive breaks, then the valves are left open as the piston comes up and CRUNCH! It squishes them back up into the head and causes damage. The Suzuki engines may not be affected by this due to the valves not penetrating far into the combustion chamber.

My ford Zetec engine was quite happy with me turning the crank by hand with the cams locked so I could set up the timing belt properly.
