I always learn something when I see other people's engine bay pics, so I thought I'd start a topic where we can post pics and have others comment on what they see. I'll start by posting my pics with a few comments.

Passenger side, looking across.
* You can see I don't have a branch tee fitting on the plenum, I've used a short length of hose with a plastic tee fitting to substitute. Finally fixing this next week. * Big washer under the coil strap - that's a fix for a flaw in the attachment to the sheet metal. Ugly but works. * Shorty transistorized Bosch voltage regulator * Bowlsby FI wiring harness * Non-OEM hoses for the fuel evaporation fresh air supply and return Attached thumbnail(s) |

Passenger side, looking down
* Yes, those are the 50 year-old plastic fuel lines. Hopefully, to be replaced later this year. * The red/black wires at the bottom are a permanent connection for my trickle charger * Battery cover and acid mat * Decel valve (vacuum limiter) in place and correctly plumbed. While this device is often though of as being solely for reduced emissions, it has a second purpose. When the throttle is closed while engine braking, vacuum in the intake manifold can approach 25 inHg, as compared to 10 to 15 inHg at idle. This vacuum is applied to the MPS, which means the full-load diaphragm in the MPS (the thing that cracks due to fatigue stress, and makes your MPS leaky) receives additional stress, leading to early failure. The decel valve limits manifold vacuum to 18 inHg, significantly reducing stress on the full-load diaphragm. A lot of people with D-Jetronic remove the decel valve - I do not recommend it. The MPS is critical to the operation of your FI system, and a rebuilt unit is expensive. Attached thumbnail(s) |

Driver's side, looking across.
* Trickle charger cable again visible. * Note the second cable attached to the battery ground point. This is a cable connected directly to the starter body to eliminate any ground drops. Attached thumbnail(s) |

Only thing of note here is hard to see. One of the cables going through the engine tin grommet is a 10 gauge ground wire that connects to the ground point in the engine compartment, and to the body of the alternator below. I figured out some time ago that the alternator bracket was the only way ground was being supplied to it. Adding a heavy ground wire eliminated a significant voltage drop here.

I swear this is an original 1974 2L engine bay, slightly modified (IMG:style_emoticons/default/smile.gif)

Somehow, this all fits without any cutting ...

Pbanders, have you run a vacuum gauge while driving? My numbers are quite a bit different and was curious about that. 17-18 at idle warm, dragging down a hill, 23ish is common. Decel works great, full open by 18.5....
My engine bay looks like a 50 year old car. Yours looks brand new. You can see my copper foil on the oil pressure sender, the extra ground to the shroud in yellow, and the cht sender wire being all ugly. Otherwise stock. And my aav bypass valve for troubleshooting. And the t for the in dash vacuum gauge |

And the t for the in dash vacuum gauge I don't have a gauge, our numbers look reasonably similar to me. Will do a temporary gauge and check it out. Is your fuel evaporation system present? Looks like you have the fresh air supply for it plumbed to your flashback trap. Looks like a 73 throttle body, as you have the vacuum advance port. What's the yellow two conductor wire at the bottom of the pic for? Is that a fuel pressure gauge in the lower left corner? |

Like others have already mentioned: "originally" a 1.8.
Unlike others, there was a bit of cutting... Attached image(s) |
