I turn it again and when I go half way it stop and at top dead center it stops but marks are still on the cam and crank
I have work on cars for many years and have not seen this before
Hello,I am Scott and I will assist you with your vehicle concern.
I am sure having worked on on vehicles, you have the information from KIA or Motor/Alldata, ect: The one thing that is VERY important on this motor is the belt deflection and the cam marks.
IN THIS ORDER ONLY "Align the timing marks of each sprocket and install the timing belt in this order. Crankshaft sprocket → Idler pulley → Exhaust camshaft sprocket (LH) → Intake camshaft sprocket (LH) → Water pump pulley → Intake camshaft sprocket (RH) → Exhauft camshaft sprocket (RH) →Tensioner pulley"
Now if you are hearing a click, and have resistance, I would bit start the engine yet. I would do a cylinder leak down test first. I fear, that somewhere a valve kissed a piston.
The firewall cam shafts tend to have more spring tension and may spring back. I have had instances with clients having a cam spring back when removing the belt and actually, inadvertently bent a valve if returning it counter clockwise.
Play it safe, do the leak down test and if it passes, get a belt from KIA. It comes with the reference marks that carguy had mentioned, and takes the guess work out on the beck cam sprockets.
Now that is good, and odd. I am wondering if Hyundai is getting cheap on us.
If the marks are good and with the plugs out you have no resistance like you had before, start it. There is really nothing else left to do or check. The leak down test verified no leaks at the valves, which would have us assume that there is no damage. As far as the clicking, if a HLA has bled down, that could be the noise.
when I turn the engine one rotation back to TDC it stops
No scott when I turn one time no more noise but it stops at TDC then hard to turn one more rotation but timing still in
Actually, once you pass TDC and the exh valve opens, resistance should diminish. until the next cylinder loads up. It will be a repeat process as the crank turns. Resistance, ease, resistance, ease.
On another note and not the issue you have, there is a campaign on the crank bolt to not reuse it and to replace it. KIA #072
With my experience with interfernce engines if the valve ben the engine will not turn at all the belt on this car did not brake.I replaced belt,crank bolt.all pulleys,tenioner,water pump.
Scott one more thing it still fell like it's hard to turn at some point on a full turn
Have a good weekend
