Engine Question

I know some of you guys are the Daewoo engine goo-roos, which is why I need you help explaining something to me.

Okay I heard something about when your timing belt breaks your entire engine goes to sh*t. Can someone give me a detail reason to why this happens? Please do not be afraid to be technical.

the daewoo engines are called interferance (sp?) engine, which means that the valves if not opened and closed at the right time they could hit your piston and cause damage. to when the timing belt breaks the piston will still move from momentum while the cams stop. so your piston will most likely strike a valve. But if your lucky it may break when the valves are closed( very unlikely) a non-interferance engine has a saftey gap between the piston and valves so there is no chance of striking each other.

the "interferance" engines are the 16v models... the 8v are non-interferance...

Just a little correction here... not all 8 valves engines are non interferance, mine is 1.5 8 valves SOHC and it is an interference engine.

this may be because i got hight compression ratio on my Lanos (9.5:1) than other daewoo 8 valve engines in Racers or Cielos (8.5:1)... anyways my mechanic confirmed that a snapping timing belt on my engine will cause bent valves.
