Adventures in Air Conditioning and also Fuel Tank Removal
Been awhile since Ive posted here. I am in the beginning of replacing the AC Evaporator and associated repairs. I just pulled the Shut Off Valve (8 in the image) and charcoal is coming out of the lower vent tube (9 in the image). I imagine this is not typical. I have had a slight fuel smell in the frunk and occasionally the cabin after the car sits for a bit so Im also on the lookout for that source while repairing the AC.
Is the charcoal Im seeing indeed from part 8? I am assuming that it should not be coming out of the valve, is that correct?
Thanks
Jim

Update. See photo. AC has been inoperable for a bit. First noticed at VIR when we found a green puddle under it, coming from HVAC drain/vent. So there's got to be a leak or hole somewhere. However when I opened the mounting block in the photo, quite a bit pop pressure was released. There must be a valve that allows pressure on w=one side and none on the other?

I did this a couple years back and from your posts I'd recommend shelling out $ Bently manual (if you going to do a fair bit of diy) and Google 993 replacing evaporator and check out the hits on p-car.com, pelican and here on rl.
Good luck, it is a satisfying project. 👍

I have the factory and the Bentley. Great resources although there are many discrepancies on torque values between them from when I rebuilt the engine a few years back. Im using Pelican Parts how to article which is pretty decent but there are some missing steps and photos Ive noticed.

I did this too a couple of years ago. Take lots and lots of photos taking particular note of actuator lever positions on the suitcase to aid in reassembly. I found the 964 forum helpful with tips on doing a complete rebuild.
I split the suitcase after removing it from the car, some threads suggested splitting the suitcase in-situ to avoid disconnecting the fans wiring harnesses from inside the car behind the dash. I had a look and thought that was too much trouble and as for splitting the suitcase while still in the car, kudos to you if you have done this. I cut the wires. When the suitcase went back in you can't see where the cut and rejoin was done.

Impressive how buried that evap is.... I dont remember how long it took but I work slow, I do remember thinking I don't want to do it again and this must be a pricy job to get done by someone else...
I think getting the suitcase out is prob the worst part - and you are over that hump. The rest is making sure stuff is super clean and sealed nicely and done to spec.
Nice one.

Price wise, had a reputable Bay Area Porsche shop replace my evaporator in 2022 and labor was $1600. Way better than I expected. No way I would tackle something like this myself.
