On. An Indica petroll or diesel there aren't aany timing marks as to say, firstly remove cylinder head, then attach a power bar or ratchet with socket to to bolt on crank shaft pulley. Rotate the engine anti-clockwise until piston one is at TDC (highest point it can go). Then at Te front of engine halfway down the block where engine meets bell housing there is a hole to. Insert a 8mm long bolt, this will lock the crankshaft. On the head on the cam shaft end cap is a hole, insert a screwdriver to fit and rotate cam with. A ratchet until the screwdriver slots in place and the cam cannot move. Replace the head, torque the bolts, fit the timing belt and tension it. Once this is done remove the locking bolt and screwdriver, Replace the cam-tappet. Cover and start the engine

Just remove and clean the IAC valve and replace if necessary...
