92 Toro, help with vacuum line

[Sgolds]

92 Toro Trofeo with 3800 engine
I removed a vac line from the silver canister looking thing in the drivers lower front of the engine, there's a black plastic line that goes across the front of the engine and connects with a rubber vac line (pics coming)

Problem is, the plastic line and the canister are 2 different size fittings. Anyone know how the factory did it?

Also, I can turn that silver piece around in a circle, is that normal or is it loose?

Thanks for reaching out about your '92 Olds Toronado Trofeo. It sounds like you're dealing with a couple of common issues on these cars. Here's a breakdown of what's likely going on and how to fix it.

Relating to the vacuum line connection: The problem with the vacuum line and the canister is a classic case of a missing part. The plastic line and the silver canister (which is your cruise control servo) have different sized ports. The factory used a small stepped rubber adapter to connect them. Over the years, that little adapter probably became brittle and broke off, or it was lost during a previous repair.

The fix: You'll need to get a new rubber vacuum adapter. Take both the plastic line and the canister to the auto parts store, or at least measure their diameters. The store should have a variety of rubber vacuum connectors and adapters that will create a tight seal between the two.

Relating to the rotating silver canister: You're right to be concerned that the silver piece can spin around. That's definitely not normal. That canister is the cruise control servo, and it should be securely mounted to the vehicle's body.

The fix: Check the mounting bracket that holds the servo in place. It's most likely either a loose bolt or a broken bracket. You might be able to simply tighten a bolt to secure it. If the bracket is broken, you'll need to find a replacement to mount it properly. The cruise control won't work correctly if the servo is loose.

Hope this helps you get back on the road! Let me know if you run into any other issues.
