Vacuum line spaghetti.
The wagon's turbo vacuum routing currently resembles a haunted bowl of noodles brought back by Chrysler mediums in 1985. Time to bring peace and order back to this magnificent piece of American automotive history.
Where the vacuum-line job stands.
What was actually found?
At least one vacuum hose was visibly cracked and was replaced. Other aged hoses, connectors, and routing still need a careful inspection.
Was the entire vacuum system rebuilt?
No. This is an in-progress inspection, not a completed vacuum-system restoration. The final routing and condition of every line have not been verified.
Why are the vacuum lines important on a Turbo I?
The network supports systems including the MAP signal, wastegate and boost control, and emissions equipment. Wrong routing or leaks can create drivability and boost-control problems.
Why replace one hose at a time?
Photographing, labeling, and replacing one line at a time helps preserve the existing routing while it is compared with the correct 1985 Turbo I diagram.
Can the engine be started to check for leaks?
Not now. A later compression test found 61 PSI in cylinder #1 beside three 140 PSI readings, so the engine will remain off until that internal problem is diagnosed and repaired.
The turbo wagon deserves organized breathing.
This repair log covers inspecting, tracing, replacing, and documenting the vacuum lines on the 2.2L Turbo engine. Old brittle hoses, mystery routing, cracked tees, and forgotten emissions plumbing are all invited to the intervention.
Symptoms / reason for repair

Equipment for hose organization.
Operation: organized noodles.

Every angle. Every hose. Every weird connector. The wagon knows where everything goes. I definitely don't.
Inspect every vacuum line by hand.
Bend each hose gently. If it cracks, crumbles, or sounds crunchy, congratulations: replace it!
Label critical routing.
Especially turbo, wastegate, MAP, and emissions lines. Future troubleshooting becomes dramatically less difficult this way.
Replace one hose at a time.
This is the entire strategy. One out. One in. Wash, rinse, repeat.
Check all plastic connectors.
Old Chrysler plastic is brittle.
Inspect hidden routing behind components.
The wagon contains secret hoses hidden specifically to test my skill and sanity.
Stop before running the engine.
The wagon now has a confirmed cylinder #1 compression problem, so an engine-running leak check must wait. A visual routing check can continue with the engine off.
Document what is complete and what is not.
One cracked hose has been replaced. The remaining hoses, connectors, and final routing still need to be verified before this job can be called complete.
Current spaghetti evidence.
What went sideways?
So far, the situation is wonderfully chaotic. I replaced one obviously cracked vacuum hose, but there is so much more to inspect.
Final result
Completed
One visibly cracked hose was replaced. Still unfinished
The complete hose condition and routing have not been verified, and no engine-running check will be performed while the cylinder #1 compression problem remains unresolved.
What supports this inspection.
The labels separate routing references from what has actually been observed and completed on this specific wagon.
Turbo Dodge Parts hosts routing diagrams for early Chrysler turbo vacuum systems. The correct diagram still needs to be matched to the wagon's Federal or California emissions configuration. View the vacuum diagrams.
Los Angeles Public Library provides access to Chilton automotive repair information for vehicle-specific service research. Access may require a library card. View the library resource.
The ownership guide explains why old vacuum routing, brittle connectors, and boost-control plumbing deserve careful documentation rather than guesswork. Read the survival guide.
The current engine record explains why the wagon cannot be started for a running vacuum-leak check while the confirmed cylinder #1 compression problem remains unresolved. Read the complete diagnosis.
One cracked hose down. More routing to go.
This job is paused with the larger engine repair. The vacuum system still needs a diagram-checked, one-line-at-a-time inspection before it can be called organized engineering.
