My camshaft sprocket does not have the notch in order to align it with the TDC mark on the head.
I'm stuck since i also took out the crankshaft pulley and the lower timing belt cover so i cannot locate the TDC.
Should i just reinstalled everything and then try to find the TDC for the crankshaft and camshaft.
I also forgot to mention that i have not taken the sparkplugs out; therefore cannot turn the camshaft sprocket or crankshaft
Here it is the camshaft sprocket and camshaft area.
