Before someone says it, yes I have done a search but wanted to make DOUBLE SURE.

Is the camshaft synchronizer problem also associated with the 4.0 SOHC?? Or just the 3.0 Vulcan and 4.0 OHV?? I was reading about a constant squeaking coming from the engine bay when other people had this problem, and lately my truck has had this very minor (almost un-hearable) squeaking when running/idling.

I think it's the idler puller on the engine actually, but thought I'd see what the experts here had to say first. So....???

You can tell if it is the camshaft synchronizer by touching the top of the sensor while the motor is running. That is what I did when mine squeaked.

 

I'm asking what engines are affected.

Well you will know then =)

 

Ok, you're not helping to answer the question I originally posted. So don't bother anymore please. I appreciate your enthusiasm but it's not answering what I was asking.

Maybe someone else has a better idea of what I'm asking...

The 4.0 SOHC has a Camshaft Position Sensor but it is a totally different part that bolts to the driver side cam cover and reads directly from a toothwheel on the camshaft. There is no Synchronizer in your engine. If you have a chirp noise, it might possibly be caused by something in the accessory drive - belt, pulley, tensioner.

 

the squeaking on moms 04 explorer was the harmarlic balancer might check yours

 

Thanks guys. That's the type of answers I was looking for. As I said, I think the squeak is actually an idler pulley. I'll have to investigate it further.. I just wanted to be sure, after reading about the camshaft synchro problems and getting paranoid.

Thanks again!
