283,000 miles timing belt broke while driving. Replaced no compression on cylinder 1 and 3. I'm assuming it now needs valve job. Motor turns freely no unusual noises. Took valve cover off and everything moving properly. If I change valves will it fix problem?
08 kia sportage 2.0 no compression in 1& 3 after timing belt broke

Time to pull the head and see how much damage there is.
If you do it, please post pics. We’d like to see the results.
You sure you put the timing belt on correctly? If it was put on 180 degrees off wouldn't some of the valves be open on the compression stroke? Assuming it's non-interference engine.
Rats! Original belt?
I'm not sure if the engines are the same in a 2000-2008 Sportage, but my wife's car blew a belt on her 2000, and it ran fine after they replaced the belt. Apparently is wasn't a interference engine.,,
All 2004-on theta engines are interference type.
Bent valves, Is it really worth all the work AND money for a HYUNDAI with almost 300,000 miles on it? I would say she gave up the ghost on that one.
How many miles were on that belt. Surely it couldn't have lasted 283k.
But nonetheless she's mashed potatoes now.
It's not worth the time to take the heads off, simply removing the spark plugs to check with a snake camera to see cylinder damage on all of them should be enough. If that steak looks well done inside just chuck it and get another.

$75 for a junk yard head. Is the transmission and body still nice?
It’s an interference engine so……I’m sure you have a few bent valves. Pull the head and do all the work or buy a used engine with fewer mile.

That year Sportage was still using the 2.0L Beta II in the 4 cyl models. It’s worth saving if the rest of the car and transmission is in good shape. That’s a solid engine.
With that many miles putting a good head on it is a gamble. It's likely to lose the bottom end a few weeks after.
General but related question:
I know there are quite a few non-interference SOHC engines.
Are there any non-interference DOHC engines?

The DOHC 1MZ-FE on my old Sienna is non-interference but the SOHC F22B2 in the Accord is not.
Good to know, thanks!
