The 4.0L SOHC engine for Ford Explorer 4x4 Mod 98 is 6 cylinders in V, I need help to put the engine in Synchrony, since the gears do not have marks to put it on time, since when the fault was detected, some chains were broken and the tensioners. So now you have all the pieces for their assembly, although from the beginning when we disassemble the distribution, we notice that the gears do not have a specific mark to put it on time, so I request help if anyone knows or has a diagram, or has photos that show the time put in time of said engine. I have found some diagrams but they show that the gears have marks but those I have do not bring it.
