Since its a double over head cam then yes you need to take it off and also need to take the air filter and possibly take of the right front wheel.

Kia optimus recall list

A history of head work will have to be known to explain this fault If the head has been removed and milled flat ( warped head form over heat or other problems) and the cam bearings are not tunnel bored to put them back in line then the cam shaft will break very quickly. To show why take a piece of soft substance between your fingers ,bend it in an arc and turn it in that arc and you will see that it will fatigue at the centre of the arc and break. With the cam bearings making the shaft fit that arc and the shaft is turning then it will break.. Mazda had adjustable cam bearing posts and both sides of the head had to be machined or the posts had to be shimmed to allow the shaft to run straight. Remember there is very little load on a cam shaft that would cause it to snap so thoroughly investigate the alignment of the cam bearings.

Cam bearings

Remove the rocker cover to ascertain the damage done . It may not be bearings but seized valve in the head. To fix cam bearings properly it may necessitate the head removal and machining both the head surface and then the bearings should be line bored to realign the cam shaft correctly. Some Nissan products have the cam bearing housings adjustable with shims to align the holes correctly and if not done will break the cam shaft. IT may be the cam shaft is broken and jammed . What ever it will not be just a case of putting in new bearings until you have the head and bearing alignment checked out by an engineering shop.

The cam shaft journals are not receiving oil on my 1983 suzuki samurai 1.3 after there was a head job done, do you know what might be the reason?

Not without taking the head back off. Could be a problem with the head gasket blocking one of the oil passages, or foreign matter in the passage, or in the oil holes in the head for the cam bearings.

Have cams out of head. need to know chain timeing marks for variable timing. thanks 2005 kia spectra 2.0

get a chilton or hays manual from a auto parts store it will show you the diagram.

listen to me carefully. find out where is piston #1 pull the spark plug out and stick a long flat head screew driver in the hole where was the spark plug for piston #1 and turn the crank-shaft untill the screew driver hits the highest point.
what this means, the pistons go up and down,ok.
now, the screew driver has to come up if it go back down just a little your fucked.

leave the crank-shaft for now. the cam-shaft needs to be properly aligned if not you can damage the valves.

Good luck with that, it's a big job. There are no external timing marks on the crankshaft pulley, if fact the pulley is not even keyed to the crank. The best way is to remove the timing cover to gain access to the chain tensioner, crankshaft mark and balance shaft mark, you'll need a good three jaw puller to get the pulley off it's a tight press fit. There are darken links on the timing chain that have to all line up with the marks on the cam sprockets, crankshaft and balance shaft. If you try to do it without pulling the timing cover and you let any slack in the timing chain the balance shaft will most likely be out of time. I have the engine out of the car and it's still a big job, I don't know if it's even possible to do with engine in the car. There are 3 small bolts down in the area where the timing chain is, don't forget to take those out. You don't need to remove the cams to get the head bolts out. They tell you to use special tools to keep the cams from turning once chains are removed, a piece of 3/8" flat steel or aluminum plate works. On the back end of the cams there is a flat machined on all the cams when the timing marks are lined up those flats are all in a line. You slip the flat plate under the cams, you may want drill a hole in the plate and bolt it down with the valve cover bolt at the end of the head. I bought a Haynes Manual for that car, it's not the best, but it gives you most of the information you need. Make sure you get all the gook out of the bolt holes use blow gun with a long line on it, like a piece brake line. Spray some brake parts cleaner or carb cleaner in the hole then blow them dry. Oil the threads and the washers or use anti-sieze. When you torque the head bolts it say's to torque them to 22 ft.lbs. and then turn the bolts another 60+60+60 degrees totaling 180 degrees or a half turn. Good luck!

I can't find the timing marks on the pulleys, the cilinder heads and the cilinder block.

it doesn't have any. there are no keyways to line up. you need a speacial plug that the crank shaft rests against and ther is a flat tool that fits into slots on the back side of the cams (you have to take the high pressure fuel pump off). if you loosen any of the cam bolts or crank bolt without them everything is out of time. why do you need timming marks, you don't have to change the chain. are you installing a new vct gear?

Still need advice

Turn crank so that timing mark on front pulley is at 0 degrees.
Remove the timing cover and you should see a mark for the cam to line up with.
You want the cam lobes on No.1 cylinder to be pointing away from the followers wether they be rockers above cam or buckets below. This will be the compression stroke.
Once the cam timing is set you can recheck the distributor. It should point to No.1.
