About to do the timing belt for the 2nd time on my J30A1 V6 engine at 240k miles & almost 18 years old. It was previously changed at 140k miles in 2010-May. Two pictures - one of the crankshaft white mark almost aligned (need slightly more clockwise rotation to be perfect) with the pointer & another picture of the rear camshaft pulley mark aligned (very well I think) with the rear upper cover mark. Am I good to proceed with removing the belt (and water pump, etc.)? In other words, which one rules? Is the crankshaft white mark to get you close & then the rear camshaft pulley mark the more precise locator, vice versa, or is something wrong?
