Even though it doesn’t look like much, I’ve replaced most of the critical and small diameter vacuum lines for the engine with silicone hoses. Why blue? Because I can. (I’m able to better identify them amongst the hordes of black wires and hoses.

How’d I do it? I went into my PDFs of all the 924 factory service manuals, printed out and taped together the diagram and placed that ‘90s Windows Mouse Maze game.

After this is more electrical and multimeter diagnosis for my no-start issues. But I’ll say the sparks I had in the car were wet. Good thing I had an extra set sitting on the shelf to replace them with.
