for Toyota cars, if timing belt putus for 16 valve and 8 valve engines normally everything would be ok. just change the belt and off we go. if we drive the 12 valves 4 cylinder engines, our luck would be different. now things had changed for the better. all Toyota passenger cars now using timing chain.
for proton aka mitsubishis.... haiya..sadly still using t/belt. if snapped - damage will sure occur. the campro engines should have use timing chain. more reliable, lower maintenance and the 'in' trend now..
