I did the repair many moons ago on my brother-in-laws Turbo S with repair kit. He was in a bad financial shape and I think Porsche quoted him some stupid amount to fix it...I did it in 3-4 hours for $500 or something like that. A friend is now looking at a 92A with the 4.8 and the price is good because there is a coolant leak. Not sure where, how or why (yet) but thought I would start with my research here. Then I started wondering if the old plastic pipe issue still existed 10+ years later...or is this 4.8L a completely different engine/design? Thx.

Ahh…thank you. I see the flange depth as the give away and also found this better image too.

Been out of the P-World for some time and we are thinking of picking up another 986/7. When doing my research on the over discussed IMS discussion there is only one piece of info I'm not seeing in the 101 articles and videos I've watched. Can one tell the double vs. single (say on a 2000 base) from looking at the cover on the IMS when the flywheel is off...or does the IMS 3 bolt cover need removed for proper identification? A bit confused on how to tell w/o going full into pulling git out. Thx.

It's fun to see after nearly a decade my original procedure is still going strong...if not hard to find! Wish I had all those old school files presented in a way better! I miss my 986 and hope to be back in one in the near future...just hope I don't need to cut open the air box again!

Sorry but I have no recall of the specific ways things were attached in there. I dug up my write up with the terrible and small photos and it was little help to me. I don't know what I ever did with the original photos but they are nowhere to be found. I do recall I stumbled on this fix 100% on my own and I"m not usually thrilled to cut something open without a plan. So I must have found some good Porsche drawings that explained what was going on in there and then looking at the design from the cowl made it logical. I've seen guys of all years on the 986 thanks me for this fix so I'd be surprised if the 996 which is mirror of the 986 from the doors forward would be so different. I don't doubt you are correct that my procedure doesn't apply...just surprised! Do you have a durametric? Is there a service position something must be in to get things in the right place for removal? Is the door made of a tin like metal or did they update it? Or do you need even see it? I've cracked open dashes on a 97 Passat Tdi (air box) as well as a 2008 Vw Touareg and I can tell you that VAG does a terrible job of making serviceable parts (blowers) accessable. At the same time they do a pretty good job of making the dash come apart (compared to Saab and Volvo) but you'll never get it back 100% unless you are surgeon. I always has some screws left over or a hole that won't line up and I chose not to put that hole in! Wish I was near by so I could get a 2nd set of eyes on the project for you but I'm sure you have seen the facts as they are.

I got nothing for you as to many years removed from this project. Rather surprised it would not look the same. Did you get the servo off the bottom?

Wife grew up on south end of Cow-lumbus. I have no issues shoving the great LS engine in anything that fits and makes sense but best watch this topic around those PCA types...they turn us in. I would worry about about the foam vs hole. My guess is it's a very over engineered theory or weight saver. Have my Porsche 5 more years after doing this procedure and never and issue. Sold with 120k miles and old did plugs, belt and fluids!

You are simply access the doors that divert the air from hot to cold. At first I figured the large holes were a weight savings philosophy that Porsche would utilize on any model but once i saw the same design on a 1997 Passat Tdi I had to help remove a heater core (the kind you have to remove the whole dash to access) I saw the same design. My other theory is the foam covering large holes allows for minimal amounts of air to flow which may help with movement or slamming of the doors..who knows. Could be a overly connected German think for all I know. Also...all makes and model seem to have one systemic issue that prevents it from being almost a perfect car...IMS is the Porsches for the Boxster (and other models). I buy ONLY used vehicles and pretty much two new (used) cars every 2-3 years. So over the last 20+ I have my share. In the last 10-15 years I've only bought makes and models I can research on the internet or (hopefully) have a good support group. You find out quality that nobody can get it 100% right and it's going to get crazier with more fly-by-wire stuff in the most modern cars. I've had Porsche (2), BMW (4), Saab (4), Volvo (5), Chevy (1), Vw (6), Audi (1) and I can tell you 83.4% of them get one major thing wrong! So far for me Volvo from late 90s' thru late 2007 have been hard to beat. By far my roll of the dice has them with the best engines, turbos and transmissions but I've noted other models I didn't buy into have issues...so some good models and always a back eye or two for the manufacture. The Boxster was almost perfect and really was for me other then this heater core as the IMS issue hasn't really surfaced much when I had mine. I'd love to get a 2nd generation in my budget range but I'll need the extra $2-3K for preventive maintenance. I love my VAG and Vw but man...Vw is way to much a gamble. My 2008 T2 Touareg V6 has been flawless but I've been waiting for major failure for almost 3 years, not a good feeling. Now the reality of that perfect T2 is I KNOW it's got major carbon build up in the intake from the FSI engine. I haven't seen it but I see the codes on my VAG COM about air flow issues. But I digress... Just take it apart and you'll have enough tape, foam or cardboard laying around your garage to fix it. It may be a hard for some Porsche snobs to fix it this way...but it's just a car and it's on the inside!

Looking at couple 2006 Cayanne S in my area...all have the CDR23 with Boss and thus fiber MOST. Read 101 painful posts on expensive fiber converts and to be honest I cannot remotely understand what product to buy from those supplies with their compliated and messy websites (MOBRIDGE, DENNSION, etc). So poking around on ebay because a buddy put a China Nav unit in his 2010 Vw Sportwagen and I"m seeing several units on there in the $500-800 range and all claim something like this... 1.If your car come with the BOSE optical fiber system, you need to pay 25USD for the extension cord.If your car come with BOSE, please contact us after your order! 2. Please make a note and tell us wether your car come with the bose optical fiber amplifer or not after your payment,thank you very much! One shows something called a CAN-BUS adapter included...is the analog or digital to fiber conversion maybe? Anyone took the plunge or read a good article on anyones experience? Thanks for constructive comments!

Note for those who keep finding this...I'm not hosting the write up any more but if you go back and look at my first post you'll see the attached PDF that covers all you need to know although the photo quality is very limited.

Ouch, i would have hoped they improved this design but considering my 87 Passat Tdi had this issue there are a few thing VAG won't give up...but I digress, It will eventually deteriorate enough that the foam will be gone and assuming your heater box is the same design leave large exposed holes in the mixer door. These hole will keep your heat and ac from being optimal based on your primary need. Since the ac on these small cockpits is large considering the space I didn't notice an issue but the heat was lacking. Once fixed my heat was great and the ac was disturbingly cold if needed. It could take 6 months or 6 years to come to pass. Unless you have an extended warrenty worry about it once there is an issue with heat or cold, especially if you are at the start of "just getting" foam.

CPY, if you want proper answers you have to create a new post. What you did is called highjacking and although slightly annoying to those who know how forums work...more importantly you are writing to a very small audience of people that have already posted on this older thread. Try a new thread with your question and you may get better comments. Good luck.

Guys, thanks for the comments. Didn't set the notification to tell me. The brother-in-law just got a quote for 12 hours of time...but I still don't understand what the concern is. he said the manifold needs to come off. Funny that I did the plastic pipes for him in 6 hours but the tech is telling him it's 5 hours just to get the manifold off...I'm in the wrong business! I'll pass on the T-Pipe to him to see if this is the concern and report back!
