a valley pan gasket replacement and haven't done it before, thanks.

There's going to be a bunch of dirt packed around where the injectors and spark plug go into the heads, so do yourself a huge favor and blast these out with compressed air prior to pulling either component.

Then spray the base of the injectors with some penetrant like PB Blaster so that they pop out of the o-rings in the head easier. They'll come up WITH the metal fuel rail, so use finesse and get them all freed up at their o-rings, and then start putting some lifting force on the fuel rail.

Thanks - they were moving quite a bit so I was hoping that was the answer

1) Auger out the EGR passage that runs under the intake manifold using a piece of steel cable....frey the end, and put it in your drill. (Not my invention, but works fantastic) Spray in the carb cleaner and roto-rooter that bad-boy out.

2) Remove the throttle body and take a dental pick to the EGR port that you'll see just inside the intake opening. Typically, it's crusted over completely, or almost. Make sure to get the corner down in where the EGR temp sensor lives so that it is exposed to the EGR gas heat and reads correctly.

3) Bentley says to tighten the head bolts a further half turn if the intake manifold is removed. So buy a set of valve cover gaskets so that you can do this. Since you'll have the valve cover's off, check that passenger side rear cam plug to see if it's leaking and replace it during this step.

4) Feeling brave? You can mod both the throttle body and the intake ports in the cylinder head if you've got a die-grinder, an aluminum grinding bit and some epoxy steel putty(for the throttle body where you'll break through...which is normal.)

But I'd spend some time with a bright flashlight and carb cleaner, in order to determine what's leaking.

Thanks for the additional info
