If it's suddenly wet after rain then It must be coming from somewhere externally. I think it is A/C, I've got the fear it's leaking in from everywhere now though! It's stopped raining so just had another look, the sponge you mentioned felt dry, grabbed a microfibre cloth and shoved it against it as well and it was still dry (it was cold so wanted to be sure). Took a couple of pictures and it definitely seems to be localised around the A/C drain area and looking at the lovely black growths, it's been dripping for a while!: Noticed where the rubber tube joins the plastic hose looked a little wet / not very secure: Just in case I threw on a spare cable tie, want to see if it gets any worse/continues: Carpet was a bit of a pain to get back in place though, the foam panel/tray is staying in the garage as I was getting very angry with it. I'm sure it's because the carpet isn't back in place correctly but I had to stop before I broke it. Quote Link to comment Share on other sites More sharing options...
TROOPER88 Posted February 13 Report Share Posted February 13 As I said, you need to unblock the AC drain. Its a common issue easily sorted 1 Quote Link to comment Share on other sites More sharing options...
Daboy3000 Posted February 13 Report Share Posted February 13 I saw a video where they cut off about 5mm from the bottom of the rubber bit that goes into the floor as they have the tendency to close together and block the flow. I'm glad it's not leaking from higher, should be easier to sort. Quote Link to comment Share on other sites More sharing options...

I ran a 30-40cm zip tie through it and it went through OK but can't be sure it's not got any crud blocking up the bottom. Quote Link to comment Share on other sites More sharing options...

You could take out the pipe at the bottom and pour some water in to the hole, it should come out of the bottom of the car. At least you will know if it's clear. I removed the lot and washed in the sink. Didn't realise it is meant to be taped to the side like yours is, that looks factory. I will need to do that.

That's a good shout, will probably give that a go tomorrow if it's not raining. Going to see if the mould wants to shift at all as well, it's probably too deep rooted in the foam to get it from the surface but a bit of isopropyl alcohol certainly can't hurt. The tape seems quite brittle so I expect it may be original, will probably retape it once I've cleared the drain bung out. Quote Link to comment Share on other sites More sharing options...

I suspect that was just a manufacturing 'fixture' so the pipe is in the right position when the carpet is fitted on the production line. After 20+ years of the carpet sitting on it I'd have thought that the pipe takes on the correct shape to stay in place unassisted. Quote Link to comment Share on other sites More sharing options...
Boxsum Posted February 14 Report Share Posted February 14 I had a similar issue once! I would also just have a quick look at your pollen filter. I found that mine was wet and rain had come in through there. It only happened when it was parked on an angle . The foam cover only partially covers and can let water in if the top plastic cover doesn’t do it’s job . I’m pretty sure the 987 has an upgraded full undercover.

phazed Posted February 14 Report Share Posted February 14 It has struck me that relying on that little interlocking corner panel above the pollen filter is winging it a bit! my similar aged old P38, Range Rover has a pollen filter on each side with a screw down lipped top over each with a rubber gasket. Considering they are in the same position as the 986 you wonder what Porsche’s thinking was. Quote Link to comment Share on other sites More sharing options...

phazed Posted February 14 Report Share Posted February 14 Not only do I see the interlocking plastic corner piece to the nears side of the battery critical in keeping the water out but also if you look along the line of the windscreen above it, as the cars age, the rubber seal doesn’t look quite as tight as it should be. Also look for any small gaps at the corner of the windscreen where the rubber has pulled away. Quote Link to comment Share on other sites More sharing options...

Got it all buttoned back up now, rodded the bottom section of the pipe and that's both clear and empty, used my trombone cleaner on the drain grommet/hole it didn't feel blocked but it definitely came out looking like there was dirt or something in there, if I get a chance at the weekend I might pop the undertray off and see what it's like from underneath. Also gave the mouldy section a liberal spray/wipe over with some isopropyl alcohol to hopefully try and kill it off somewhat. Carpet is as dry as it was yesterday after I gave it a go with the wet vac so that's a good sign, pretty much confirms it's not coming in from outside as it was raining quite heavily last night and the car is parked nose up. I checked the cabin filter and housing and it was dry, cleaned up the sealing edge of the scuttle panel that covers it too just in case. Definitely going to buy a new cabin filter though, it was OK looking but reminded me that I like to throw a new one in when it's an older "new to me" car. Annoying that this experience has put the fear into me regarding leaks though, going to constantly be on the look out for them now! Plus I've now got the wonderful job of pulling the carpet out when it gets a little warmer. Going to pull out the passenger seat at the weekend if it's not raining and adapt a tupperware container to act as a shield/protector for the module under the seat. Thanks for your help @phazed @TROOPER88 @Daboy3000 @½cwt and anyone else that's pitched in! Only part I'm not 100% confident in is the rubber elbow joint so might have a look and see about replacing that when I do pull the carpet up.

Daboy3000 Posted February 14 Report Share Posted February 14 I've sorted/checked many of the leak points on my car, so if you have any other problems let me know. Many people have no issues at all and my last Boxster didn't leak, so don't worry too much. 1 Quote Link to comment Share on other sites More sharing options...

Yes, both corners look pretty grotty. Not sure what to do really. The screen will need to come out to treat a bit of rust when I get it painted but I don't know when that will be. A windscreen guy I know can't get 986 screens. I'll have to hope a stone cracks it, maybe a seagull will "drop" a stone on it!! Quote Link to comment Share on other sites More sharing options...

Yes the pollen filter was soaking wet and water was coming through and making the passenger carpet wet. Mice had nibbled away at the foam cover so I just put a small strip of tank tape along the joint line of the hard plastic cover and this fixed it. The independent Porsche specialist I use said even when the foam tray isn’t damaged if the car is parked at certain angles , ie on a slant water can still drip in . The 987 has an upgraded full cover to resolve this. He said everyone jumps straight to blocked drains and a/c pipe but in many cases it can be simply this. 1 Quote Link to comment Share on other sites More sharing options...
