SOURCE: Timing Chain and Valves

I think it's an interference engine but you can check quite easily at this point if the valves are bent. Pull all the spark plugs out, turn the crank so that all the pistons are 1/2 way down their bore, get a piece of fuel line that is just the right size to thread into the plug holes or a special fitting for this purpose, and blow into each cylinder after you have turned the cams in succession so that the valves should be closed at the hole you are blowing into. If a valve is bent, you won't have any trouble blowing into the cylinder. If it's good, you won't be able to blow very well at all.

Are most gasoline engines none interference?? Mr technical guy??

SOURCE: 03 kia rio-24000 km.will valves hit piston if belt breaks?

yep valves will hit piston if timing belt brake.timing belt keep your valves and piston timed.when intake valves and exhaust valve open.piston is on down stroke.the timing belt keep pistons and valves from colliding.your timing belt change is due at 60000 miles.but in some cases belt need to be inspect at 30000 miles.to be on the safe side.

SOURCE: Are the V6 engines Free spinning?

Hi Lukegerny,
No,the V6 engine is not free spinning. If the timing chain breaks, leaving the valves open as the piston moves through its travel,there will be damage to the valves.How much damage will depend on speed of engine and length of time it ran. You can perform a leak down test to check the condition of the pistons and valves. It will tell you if the valves are not sealing,without having to take it apart. Thanks,Chuck.

if its a 2.2ltr its a timeing chain and the r known for failing they have a cheap plastic slide that wears out prematurely causing the chain to jump or sometimes break. ive fixed a lot of them so i dont think its an interferince fit engine if its v6 4.3ltr u hardly ever have a problem with the timeing chain. its usually the gear at the bottom of the distributer wears out
