Trustees: Turns out that I need to pull the newly installed 2.0 and get it back to the builder. A poor oil pump install has it pumping oil in the wrong direction. Since the BB still has FI, it has hundreds of vacuum lines, fuel line, and electrical connections I really would like to avoid disturbing.
My question of the day is: is it reasonable to assume that I can remove the intake runners, and the plenum, with the injectors and injector boots still attached, as a unit ? The new injector boots from JB were an absolute B to install without ripping them. This was with the engine on the cart! As it ended up, I needed to install them AFTER the engine was in place due to clearance issues lifting the engine into the bay. I would like to avoid that exercise. To drop the engine I removed the fuel lines from the injectors. That left plenty of clearance. Ideally, I would like to remove the intake runners with the plenum and injectors in place, and reinstall with only new intake gaskets. Am I dreaming? Or is this possible? Cheers! Robbo |

The engine can be removed by just removing the air filter box. Everything else topside can remain in place.

I have the engine out and on the cart. I would like to remove the intake runners, with the plenum and injectors still attached. Glad you posted, I was just going to send you a note on the backup light wiring. There is no continuity to the #4 pin on the 12 pin connector. I'll send the harness your way on Monday. In the interest of a more elegant installation for a starter relay. I'll reach out to you via email with some thoughts. Once I have them organized. robbo |

(IMG:style_emoticons/default/huh.gif) Im a little confused as to how that would even be possible, unless you are just talking about excessive clearances pumping it back into the sump? It only pumps one way, install it wrong and its not pumping anything at all. |

It all comes apart super easy. Just get some painters tape and a sharpie mark the wires and vacuum lines. It feels like a lot of hoses at first but really there are not that many and they all do important things so it's not like an 80s smogger or something.
