Unless is an experiment in acoustic, I found it to be a clever arrangement of a wind instrument next to strings!

Oh yes, the DP sounds very good! :) I sometimes crank down the audio and listen to 5 cylinders singing through that 3" pipe =)

Next summer is rear subframe drop, for $700+ bushings replacement and rust proofing the connection spots where subframe gets bolted to the chassis. They are/were rusted on all P2s I had/have.

Sigh... Rust proofing starts with the first owner of the car. My Tundra will not rust, I'd guess ;) Still has to clean my garage floor from the sticky 1600 drops.
After the rear suspension refresh, I imagined resurrecting the subframe at some point. But, here are my parts list for exhaust maintenance - curing the tapping noise.

starting from the exhaust:

MANIFOLD @ EXHAUST
1 Exhaust Manifold Heat Shield 30622418
1 Gasket Kit. Exhaust Manifold. TURBO. 271802
4 Flange lock nut 985868
4 Stud 1336261

TURBO @ MANIFOLD
4 Turbocharger Washer 419401
4 Turbocharger Stud 982667
1 Turbocharger Gasket 8642449

CAT @TURBO
1 Turbocharger Gasket 8642450
3 Lock nut 977209
3 Stud 1357769

PIPE @ CAT
1 Gasket 9179056
2 Flange screw 982797
2 Flange nut 985921

After the recent idle and engine cut-off issue during a road-trip, it is somewhat stable but not fully; more here viewtopic.php?f=9&t=95124.

The fresh air pipe, TCV and MAF were replaced, but the stutherring to smooth idle continues after 880 miles of Relearn drives.

Close to 202k-mi

Any thoughts?

My 220k miles engine problems ended up in a burnt exhaust valve ;)

Thank you vtl!
Would VIDA show any relative code to guide the next step?

The tapping noise remains an unresolved mystery. Here is a video clip taken from the ground on passenger side https://www.matthewsvolvosite.com/forum ... p?id=51383.

I am open to any pointer. Intermittently comes and goes away.
The intermittent tapping noise was due to a missing (deteriorated and fallen) hose conduit, a 3 inch rubber piece located a foot behind the subframe on passenger side. The hard line #14 travels along the fuel line and connects charcoal canister to purge valve at the fan assembly. The open line made the noise escape the vacuum chamber.

The makeover is coming to close. All critical parts are Volvo, and quality OEM parts. A ballpark cost of $4387

Here are some highlights since October 2018.
- Lubrication system service: oil pan, oil cooler, oil pump and the PCV
- Fuel system service: fuel filter, fuel rail, and injectors, and intake manifold service
- 2nd Timing Belt: All TB parts, water pump, all serpentine belt parts, front and rear cam seals, and VVT hub replacement –– learned how to manually align crank marks
- Rear suspension refresh: Spring, shocks, links, spring insulator, and shock mount, and coated the rear under-carriage with rubberized rust resistant paint
- Cooling service: radiator, thermostat, hoses, and temperature sensor
- Steering pump service: fluid and seals, and inner and outer tie rod
- Front Brake service: calipers, pads, rotor, and in-situ brake line flaring and repair
- Air Intake service: all hoses and pipes, air filter, turbocharger, intercooler, MAF, TCV, MAP, ACT sensors, and upgrade to XeMODeX throttle body
- Alternator service: replaced INA OAP, upgraded to Volvo Voltage Regulator - Bosch 8637851
- Replaced front seats from a donor car, restored PSM module, and replaced climate control bulbs
- Many small things along the way -- paint retouch, exterior cladding restoration, protection and weatherizing, new tires, looms

Many thanks to MVS Mavericks, and pgill's $10,000 S80 Challenge

Now some serious considerations: my 2.5T blew exhaust valve at ~220k. Cam lobes showed no valve clearance (thermal gap between their backs and tappets). The donor engine I took apart in winter had about the same mileage and about the same gaps picture. Many-many more 5 cylinders died around that mileage.

Looks like 220-240k miles is a Rubicon for valve clearance, not to mention completely worn out valve stem seals.

A thread with 250,000 Miles Climb could guide us there.
Will VIDA provide DTCs to help with failing engine? Is ECM-4801 relevant here?
