Gordon,
My friend recommended Eric Jones here in Glenwood OR, so i picked up my car today and its at Eric's shop right now, he mention he might just drop off the whole engine/transmission.
I will keep you posted.
BTW the previous shop was actually very nice in the end and didnt charge me for the scanning,nor the lost time ;-) and 2 trips top hve the car towed.

I'm going to attempt to do mine this coming week. Had planned going through the intake area. The two bolts to take it out are easy as pie with the wheel removed and so are some of the lower lines. Problem is you can't see any of the upper stuff to remove, and some of the clamps are crimped. I plan on removing the drivers upper intake and dropping the engine off the mounts till it hits the crossmember and that should gain enough access to do the work from what Ive read. My AOS is leaking antifreeze from somewhere and that is why I'm replacing it, it may just be one of the clamps but has to be removed to fix that pretty much anyway. And after 76k i'm sure it's time.

I may do a write up since there is not a good one anywhere that I can find with pictures.

I am sure a lot of guys would appreciate a good, detailed write up, with pics where appropriate and needed.

Steve owns and operates Rennsport Systems in Portland since 1976. He's as knowledgable about Porsches as you'll find anywhere, and he's in your backyard (well sort of).... http://www.rennsportsystems.com/

Steve is one of this forum occasionally and is always helpful and patient willing to answer questions. I think this thread sums up how most of use here feel about his presence and contributions....

Okay,

about 1.75 hours in and I have the upper intake about off. The 6 intake bolts are easy except the last one, it really really sucks. It takes the correct extensions and sockets and a little bit of luck to reach.

Anyway that is not the big stumbling block, the rear crossover tube has 4 hose clamps. They are facing the front of the car. Anybody want to chime in hear about how you got them loose.

Also I have already broken two lines. One vacuum line just busted when I moved it, and a small water line near the alternator has a plastic coupling that just broke when I tried to pull the hose off.

my clamps faced forward too... I used lowered the motor to gain access....look up from the muffler tips and there are 2 really big obvious nuts... a jack under the motor and you can lower it all the way down to the cross member at the tranny after removing the nuts...

also the clamps rotate one direction with effort... dont remember which way but I was able to turn them till I had access - and a 1/4 ratchet set with a LOT of extentions saves you from reaching all the way in there... they will also come in handy for the actual AOS bolts... you can remove them from the wheel well very easy, but IIRC I had to jack the motor up or down to get a straight shot at them....

good going, are you planning to replace the orings on the intake? I did .... local dealer was a rip off....$10 ea!!

one more thing... put some bright colored rags in the intake holes so if you drop anything it doesnt go in there AND the bright color will remind you to remove before re-installing the intake

I went through the intake side, without dropping the motor.... it sucked! took me 8 hours with BSing in between.

Ferd was the one who gave me the encouragement to tackle the job... I followed his advise except did lower the motor for a good 4 inches of extra room and i replaced the bellows clamp because I had hurt my had about that time and after 2 hours of screaming at that damn stock spring loaded thing someone suggested I replace it and 30 seconds later it was on

How long did it take you to do the AOS removal and replacement Ed, and would you recomend dropping the motor?TIA

ivangene

Lowering the motor - not dropping it out, YES

Took me about 6 hours? I did it in two days and took my time, didn't watch the clock (except on that damn bellows clamp!)

If I were to do it again I might opt to pull the tranny if I had the room. Its a heavy item and access is still very tight to the AOS but you have an opportunity to view the IMS / RMS and maybe decide on the clutch while doing the job

Well, my 996 is back and running again with no smoke at all after having the AOS replaced... :-)

ivangene

Time?

Are ya happy?


Would you do it again?

Tips?

afast16v

It was at the shop for one day, i am happy the car is back for sure and glad it wasnt anything else, the way the car smoked was unbelievable, in 5 seconds you would think the car had caught on fire.
Obviously I didnt do it myself,like Gordon said " you might need lots of tools " and i didnt know if i had everything that i needed plus the time to do it, i handed it to the experts.
The only tip would be...I really would like to learn how to work on this cars, they make me feel somehow intimidated.
I wouldnt like my car to break again :-)

OK - I confused this thread with another DIY AOS job....

well the good news is it is fixed, and that you "want" to work on your car. The AOS is fairly complicated job, but by all means not so bad that someone with time and tools could not attempt.

I think a good starting place would be an oil change or a brake pad swap. - Removing the air box and checking your belt and pulleys is another very simple task that will halp gain some confidence. The other thing that was a big help for me was just jacking the car and removing the wheels (even if just to clean the wells) - it all builds your level of comfort.

Tools take time and money to aquire - start with a basic "set" of quality tools and a small box to put them in. Each job you undertake, buy a couple more and in time you will have the things you need. Most jobs dont take 1000 tools, but the ones that you need come in small sets so you end up with quite a few tools. All said and done when I got dont with my AOS I bet I could have held all the tools used in one hand....(except the jack and stands)
