#11 of 13 2005 Ranger 3.0L multiple codes by bigd2011

I came across a thread earlier today stating the same symptoms I have with my engine. It involves replacing the o-ring on the IMT valve. However, I simply cannot find a picture or a good enough description to show me where the IMT valve is. It is a 2005 Ford Ranger 3.0L v6. Can anyone post a pic with an arrow for me or describe it for me? Also I noticed a small amount of burnt oil drips on top of the driver side valve cover. Not enough to drip down to the exhaust but enough to notice. I pulled the wire harness off and ran my hand all underneath the upper intake and felt nothing but dry dusty metal. Clueless to where it could be coming from. Any thoughts?

I have an '01 Ranger w/4.0 v6 that developed an engine misfire. I have done the following: plugs, 3 sets of plug wires, intake gaskets, fuel filter, cleaned MAF, cleaned idle air control valve, checked air filter, cleaned EGR (but still get codes PO401 and PO402 - excessive and too little gas flow in EGR), new coil pack. Miss starts after engine warms up and it is on a pull. Has anyone seen similar problems? Can anyone help?
