If not, go back to previous steps and redo them. Clean out any dirt from the hole on the Cylinder Head where the tensioner takes its threads and place the tensioner back afterwards tightening it to 75 n.m (66 lb ft). Compress the Timing Chain Tensioner by 2 mm (0.079 in) using an appropriate tool with a rubber end, followed by the installation of the upper Timing Chain guide and bolts, as well as tightening them to 10 n.m (89 lb in).
