At least that banjo is relatively simply. Great shot, except I can feel the back strain through the photo..

The TARDIS is back on the road! Got everything put back together last night. No oil or coolant leaks that I can detect so far, but I'll keep an eye on it. No vacuum leaks that I can detect. The rewired ECT sensor is sending a good signal and valid readings according to OBD diagnostics. Everything in the engine bay looks and sounds good, driving is good and peppy, so I'm happy.

A few lessons I learned:

- Always use new washers/bolts whenever Volvo recommends it.
- Always use proper Oetiker hose clamps where Volvo recommends it.
- Genuine Volvo PCV hoses are nice, soft rubber. Don't use an OEM/aftermarket hose that feels more solid.
- For hoses that use reusable worm clamps, pay close attention to the positioning of the clamp and screw head whenever you reinstall it. Make sure you reinstall it in a position that's as easy to reach as possible. This can mean a huge time savings for future work.

P.S. I rented my wife a Chevy Traverse 2018 Premier trim edition to use for the week while I was working on the Volvo. That thing is huge and the technology inside is crazy. She loved driving it. I didn't drive it but rode in it once and it was quite nice inside. She was a bit sad to return it and go back to the '01 Volvo, but grateful that I was able to get the work done myself.

Here's a photo of our rental parked in front of an XC90.

Hi PRW. Glad you found that oil leak and got her on the road again.

When that elbow hose was leaking did it throw any codes? I'm tracing down the ECM-121B code

The only loose hose I have found is that PCV elbow hose to the block. Mine is leaking oil but not as bad as yours. The clamp isn't crimped down tight enough. Before taking off the intake manifold I may try to replace that loose clamp with a SS fuel injector style clamp.

Nope, this didn’t cause any codes, just an oil leak.
