My Cylinder air guides don’t look right…
Every manual and book that I have shows a different arrangement than the guides that I pulled out of my engine.
I have a 1985 3.2 that appears to have never been taken apart before I started my tear down. All of my guides have cut outs, including all 4 of the corner pieces. The corner guides: one set of two is cut differently than the other set of two. All of cut outs are punch cut with perfectly rounded inside corners, so I do not think that they have been modified by anyone. Do I have two wrong air guides, or is this the right set up for my engine? If I do have the right guides, I am not sure which corners go where! Any input appreciated. Thanks, Dave ![]() Here are just the four corners: ![]()

Hi
Think the link below will help you understand the factory air guide modification for 1964 to 1977 engines: (Production equivalent embodied on later engines like yours.)

What you have is correct. The works drawing has the blades going showing both sides of motor.
The 1 inch cutout on the centers goes to the outside, the notched ends go against the case. Bruce Last edited by Flat6pac; 10-04-2025 at 03:21 PM.. |

Thanks guys- the Bentley manual and Wayne’s book must have been showing the older style. Everything I was looking at had one of the end guides with no cut-out.
Huge relief!

Yes, that is exactly what I’ve got. I need to get an ‘85 service manual…
