10. We removed the EGR valve and modulator. Pretty easy operation.
I've never pulled one of these before so I don't know what I'm looking at but I'm guessing it isn't good...intake on the valve where it bolts up to the intake manifold was plugged with carbon buildup.
11. Removed the throttle body. Pretty easy also and found more carbon buildup on the backside of the butterfly. Any thoughts what is causing this? I'm surprised to see this on the fuel delivery side...
12. The instructions from the Toyota shop manual (btw, big thanks to Sean from TN for providing a copy for us!) show removing the intake manifold next however we decided to remove the delivery pipe, injectors and move the wiring harness out of the way. Even so, it was a bit of a Houdini act to snake the tools in there to remove it...
We left the delivery pipe attached to the fuel line and pushed it up out of the way. It's the one lying vertically in the pic. Then pushed the wiring harness up over the intake to give us a clean shot at the manifold bolts.
On our third set of gloves at this point...did I say the engine was a greasy mess? Still kicking myself for not cleaning it before we tore into the project...
13. Removed the intake manifold.
Now have a clear view of the back side of the motor and a full shot of the slime pit. Called it a day.
