Hi guys,
I just bought a 05 4.0 sohc explorer and i have some questions. First off I bought the truck assuming that the timing guides were bad (common problem). First question what is the best way to tell the timing guides are bad? The truck ticks when the engine is cold, its 20 outside this morning and it ticked for probably 5 min till it warmed most the way up. But once it gets almost to operating temp the ticking goes away were you can't hear it even if your looking for it. I used a stethoscope and found the tick on the driver side valve cover on a little nob looking thing that sticks off the valve cover. By my guess is that the nob would be above the first valve on the driver side. From what i have read is that these fords have hydraulic valve lifters that can loose their pressure and they pump up with oil when they go bad, and that they cause no harm to the engine while they pump up. My original plan was to pull the valve covers and inspect the valves to see what was going on but the bolts for the intake are rusted out and i stripped 3 just trying to get them out, so i will have to tap those out if I want to get further into this. The truck runs very smooth and i cant hear anything when the truck is warm which makes me almost doubt the guides are bad because i should hear something even when the truck is warm right?
