I have the Kia manual for the 2008 Sorento.Although this could be done, its not industry standard.
What is important is the teeth on each cam sprocket and their relationship to each other and the crank shaft sprocket.
Cam timing is very important. Be sure you get it correct.
Get ahold of a good repair manual and read up on cam timing.
Don't loosen the cam caps. Not necessary. You can rotate the cams via the shaft itself. Look for a set of flats somewhere on the cam shaft that will allow you to put a wrench on to rotate it. Both the intake and exhaust cams should have these flats. You need to overcome the valve spring force, but that should not take too much effort. You need to know where the 'dots' need to be in relationship to the crank at TDC. Hope this helps!I have the Kia manual for the 2008 Sorento.
This issue Im having is resetting the timing. The Timing Marks are off on the Sprockets so the Intake and the Exhausts do not line up. I currently have the crankshaft set at 0 and Cylinder #1 is a Top Dead Center. Questions is do I need to loosen the camshafts bearing caps and manually turn the sprockets (with the chain off) to set them to the right marks?
I can move the cams via the 14mm bot in the front of each. AT TDC, The whole intake cam on the left side (Cyclinder #1 ) moves and I can put it at the right spot for the marks. The exhaust cam freely spins by hand because only the front rocker is moving. On the right side, I going to assume I'm going to have to move cylinder #4 (intake) to TDC to align that side.....correct?Don't loosen the cam caps. Not necessary.

#1 How do I get the right side aligned if they are stuck (hitting the pistons)? Do I go back 45 degrees (counterclockwise) then move forward?Don't move the crank. Both banks of cams need to be in synchronous relationship with the crankshaft or the engine may not run smoothly, or not at all. Rotate the cams only. Because these engines are 'interference' designed, very low squish area (aka valves can hit pistons) use due care when spinning the crank or cams. A piston at TDC (either intake or exhaust) can contact the valves if your not careful.
Valve stems can bend easily. Don't force things into place! Good luck. You can do this!
In this case yes, move the crank and then move it back. Other ways which work are to align the cams with the heads off the block. Or you can loosen the cam caps to prevent the cam from opening the valve all the way. Normally 10mm will suffice, but all OHC engines are different. Your second question, depends on the firing order and how the cylinders are numbered....
I prefer to align the cams with the heads off the block. But, not always possible.
ps....do this without the timing belt installed or you will never get the proper time.
Snapped under the first bearing cap. The only damage I see is in the cavity were the cam shaft sits.Crap! That is not a good sign....broken camshaft.
BTW, no issue with any special sequence to remove the cam caps. Just make sure you put them back in the exact same position and same journal. The caps should already be marked with a number (1E, 2E, etc.) and an arrow pointing to the front of the engine from the factory. If not, clean the top of the cap and mark with a magic marker as described. When re-torquing start in the middle and work your way out to the ends with three seperate and progressive torque levels, finishing to PP specifications. Double check your torque reading.
Be sure to lube the lower cam half round and cap with good quality synthetic motor oil prior to installing a new (used) camshaft.
Now, a broken cam is not very common. Pieces of the cam may have found their way into other rotating and reciprocating engine components. Other parts close by may have been damaged by the initial event. Look all the parts over very carefully!
Once you get the broken cam out look closely for any missing pieces. If you can't come up with all the parts and pieces that spells trouble, and a whole new set of procedures you will need to follow.....
