Having recently decided to finish what I started a million years ago I am reassembling the intake/plenum on my 1989. She had a lot of leaks and needed the rubber rings, lower plenum rubber and other aspects replaced. I have the upper and lower intake together and now need to bolt it to the block and start reassembling the fuel, vacccum etc.

I am interested in any pictures or diagrams someone might have of the intake area of a 1989 420 SEL. Mine has sat for a year and the original pictures are missing.

Here's the areas I am trying to figure out, any exploded views, pictures or diagrams would help 1000%.

- Vaccum (have this already)
- Throttle Linkage
- Air injection routing
- General pictures

I have the manual (online version) that is floating around the internet but it doesn't seem to cover the detail I need.

Any suggestions or otherwise appreciated. I am searching the forums, google etc but haven't found anything concrete yet.

hey man, have you received any diagrams yet? I need the vacuum diagrams as well as the rest.
I appreciate any help in this matter.

for answer

The factory manual covering this topic is definitely vague. I am working on the same project right now....I can take some pictures of the process....I will try to remember to do that. I'm one of those weirdos that can dismantle something and not label anything and still remember where every piece goes.

As of this afternoon I should have all the parts I need to get it back together *maybe tonight*.
