All, after much work over the past 6 months the 928 has been running well and I have been driving her to and from work, about 80 miles round trip, 2-3 days a week. Over last couple trips have noticed the console switches are getting very warm along with the metal fertile at bottom of auto shifter. When I got home tonight I measured the temp on the switches and they were 123 degrees, ferrule temp was 121. Since the only thing under that area is torque tube and exhaust I shot the exhaust and cats.

Temp before cats was 321
Temp at front of cat was 525
Temp at back of cat 478
Temp after cats 318

Temps were taken approximately 10 inches from areas and approximately 8 inches before and after cats. I'm thinking I have a bad/plugged cat issue but wanted to throw it out there.

Thanks

 

Uh this sounds like your foam insulation pad is leaking.
Causes are worn motor mounts , this lets the drive line come away from the tunnel.

To reduce the heat drawn into the cabin,
you will need to close the windows and the sunroof and turn on the fan,
this will pressurize the cabin.

Otherwise with a window or roof open it creates a draft this will draw air in from the shifter quadrant.

The fix is to replace the MMs and/or possibly drop the TT and repair or better replace the foam pad,
they usually get damaged when the TT is serviced.

 

Thanks Stan, did have new TT bearings installed last October. Just wasn't familiar with typical temps at CC. No A/C right now so windows up is not an option, it was 82 in ATL today. So short of it is much work for a $4 repair, good thing is that's one more thing I know about for future reference.

 

the insulators (2 pcs now) are not cheap. it is not a $4 repair.

 

A short test. Remove the console switches. Drive with the windows open and you will feel hot air coming up at the switch cutout. Shut the windows and the flow of hot air should stop or being reduced.
The foam pad is not sealing properly which can depend on collapsed motor mounts (engine sitting too low) or damaged foam pad.

Test confirmed, thanks again Stan and Åke, guess a little more motivation to get AC fixed as motor mounts are good and not overly excited about pulling TT to fix/replace foam.

 

My suggestion:

Remove the console and install the 5 speed gasket - 928.424.181.04 over your auto shifter after stuffing some insulation under it and re-install the console. The gasket should eliminate the hot air coming into the cabin.

 

Thanks Kevin, glad there is a possible in situ solution!
