    Probably so and the fact that it used about a half quart of oil on a trip from Chesapeake to Charlotte and back.

        Hopefully my picture isn't getting confused with the OP's pictures. You could list every possible cause in my case and they would probably all apply.

          How many miles? Does it burn oil? Could be it needs valve stem seals, these lopos tend to foul out the cylinders closest to the firewall. Ashley's old '89 fouled out the driver's side plug and produced the exact same symptoms you described.

          two rear plugs oil fouling is common on engines with wear. Not sure if it comes through the valve seals because of the tilt of the engine, or through the PCV system because of blowby but either way thats where you see it. Is the screen in place under the PCV valve? You'll get a lot of extra oil through there if the screen is missing.

          Had to re-size the pics to get them to post.

          This is a new remanufactured engine. I'm assuming the PCV mesh screen is in place, it's nearly impossible to get back there to confirm w/o taking off the upper intake. What do you think of the pics? The first two are the "good" ones and the last two are plugs 4 and 8 with #8 being on the right and the worst of all of them.

          I believe I was first to the punch with the worn out valve seal thing

            You were. Car is at the shop that installed the engine, dropped it off yesterday. The heads were also Jasper so we'll see what they determine. I'll update once I hear something.

              VCV,
              Ashley's was so bad on #8 we weren't even getting 800 miles between plug cleanings.

                *Update*

                So Jasper has advised my shop to make some changes to the PCV system and relocate the PCV valve. Apparently this was either a running change or a TSB not sure which that Ford instituted at some point. I have never heard of this but here is a link after doing some quick Googleing.

                http://www.fordtruckclub.net/forum/s...ead.php?t=6049

                Have any of you heard of or done this modification? I gave my shop the ok to do it.

                  That is a GREAT idea. Wow. That is a downfall of the 5.0. I really do like this idea - nice info.

                    Lot of the mod-motor guys run oil separators. Accomplishes the same goal I reckon.

                          I would not use Platnum tipped spark plugs due to the need to use a "hot" ignition system as in a race car not a street car with a "street" ignition, I speak from experience as I pulled out many platnum tipped spark plugs when customers complained of rough idle. Some cars do require the platnum tipped spark plugs to run properly.

                            Here is the document that Jasper provided regarding the PCV vacuum supply reroute. Makes sense that how it was routed before would have cause issues on the #8 cylinder. Hopefully this new routing will eliminate future problems.
