U' m repairing the head on 05 kia rio timing belt slipped and juped time bending all the valves Now putting the head back on I need to know if the head bolts neeed to be replaced and how to torq

your car has an interference engine. that means if the timing belt breaks, the pistons and valves collide. best case you can have new valves put in the head and it will be okay. worst case

Yes.
You can research the procedure online or get a repair book for replacing the timing belt which you should have already.
You would also need the torque specs for the head bolts.
There is a mark on each cam gear you have to line up when putting the belt on.

the timing belt is not something easy to do if its your first time because If the timing belt broke that means the Valves are bent by the pistons going up and you will need to check the Valves on the head before you put in any new belt, If not then that car will never run. And I think you will need some help with that kind of job and right tools. Good luck bro

Did you recheck the engine valve timing (Timing Belt) after you finished? If so check it again. Timing has to be set on #1 top dead center. You probably know this if you did the head gasket.

Sadly the Kia Rio is an interference engine, this means probably at the very least you have suffered some valve damage. You may have also damaged the camsaft, pistons, and head. You won't really know until its taken apart.

The timing is electronic and non adjustable. If you change the belt and don't have it set up (positioned) exactly right , you will cause major engine damage.
Pistons will hit valves and bend them. Don't do your timing belt unless you are experienced at doing that job.

not always but to be on the safe side take the head off and check if you dont know how to check take the head to a shop get them to look at it.they shouldnt cost you anything if its good buy a cylinder head gasket and put it back on. if they are bad.its cheaper to buy a new head for the car assembled

WOW - DID THE BELT BREAK WHILE IT WAS RUNNING IF SO THE VALVES ARE BEND THATS WHY YOU HAVE NO COMPRESSION.
IF YOU HAD THE BELT REPLACED AND THEY DON'T HAVE THE TIMING MARKS RIGHT YOU CAN STILL BEND THE VALVES.
9 TIMES OUT OF 10 THE DAMAGE IS JUST TO THE VALVES AND NOT THE HEAD OR ENGINE. BUT IF YOU HAVE TO PULL THE HEAD MY ADVISE IS TO HAVE THE HEAD CHECKED FOR CNY CRACKS

yes, this is VERY IMPORTANT, this is an interference engine, meaning the valves and the piston cannot be in the same place at the same time,or it will bend the valves.then you are looking at a major repair job,think or it as insurance on your engine. please rate my fix as i strive to be the best,questions,get back to me

Hello Kia Owner,
Regarding the shut down, when was the last time you changed the timing belt?? Did you know that the twin cam 1.5 lirte motor needs a new belt every 50,000 miles or 80,000 kms.
If the belt has failed it may still be in tact but with the cogs ripped off.
Your valves have collided with at least one piston but it is good you were only idling at the time.
The motor may be worth fixing. I just fixed mine myself. I had to lift the engine after removing the axles. I removed the old timing belt and removed and rebuilt the cylinder head(big job). Two exhaust valves were boken right off and lying inside one cylinder.
Most likely your timing belt failed as well.
