I can maybe confirm this thoery about cold air ,as my AOS (2.7 987) failed on the coldest day of our winter so far ,it was -17c ,and the engine been running very rough since ,plus an oil drip down the back of the AOS ,the engine sounds like its either got an exhaust leak or induction leak or both ,plus slight oil smoke like one of those misting machines you use to get at 1980's discos

when calling a porsche center for the part they have had lots of orders for the same part ,the 987 AOS is a bit different from the 986 version and doesnt have the boot or the plastic tubes on the bottom but a hose (with one of those clips that are sometimes impossible to remove) and a spigot with an O ring ,also mounted / bolted differently

Just wanted to post a quick thanks to Brad Roberts for the write up. My AOS failed on my 2000 986 with 99,067 miles on it. Spent a couple hours this afternoon swapping a new one in. Everything went smooth and it saved me a couple of hundred bucks.

By the way the part number for the clamps with the blue retainer is 999-512-630-00 / 99951263000. It saved me a lot of time.........

75K Failed AOS

Advise needed. On my way back from Cape Cod I became stuck in stop and go traffic and after about an hour I notice my 02 Boster was smokeing. Made it off the next exit and had it towed to a Porsche shop in Hartford. Musante Motor Sport was great and I picked up the car last Friday. It was the AOS. I changed the oil this weekend and I will send it out to be analized. It seems to have a little rough idle. It there anything else I should check?

Thanks,
RJ

Cannot see pics.

I seem to be having a problem, well, two actually. One, I seem to have all the classic symptoms of a bad AOS. My second problem is that I cannot see the pics of this (from what I have read), very detailed AOS replacement DIY.

Any help would be appreciated.

Thank you.

Hey gang.

I'll "fix" all the pictures this weekend. I sold the "BoxsterSpec" domain name last year, but I still have all the pictures from the site. I'll move them to another domain name I use (986racing.com) and make them work again. Pretty simple fix, but it will take some time to get them back into place... and I was just reminded we have a track event on Saturday!! So look for them Monday morning. I'll fix them during the day on Sunday.

Last time I was in my engine bay my AOS had a film of oil on it so it may be on its way out. Do any feel the motorsports version is worth the additional cost?

I had an oil leak after a track day and thought (or hoped) it was the AOS.....but then the drip moved into the centre....gulp....track weekend over

I had partially dislodged a new 997 RMS. Could undue crankcase pressure via the AOS be part of the problem?

I'm going to be doing my AOS replacement in a day or two. Pictures would definitely save me a lot of time, trouble and headaches.

OK.. it appears everything is back in place. I just copied the folder from a backup I have and changed the URL in each post to point to the new URL.

Hit refresh on page1 and you *should* be good to go

Sorry it took so long to get the pics back up. I know of at least 10 people who have asked for the pics offline.

Life got in the way
