I know its been years but do you recall how you ended up resolving your AOS problem?

aos replaced still smoke
carlosvquezada replied to andrewamberleigh's topic in 986 Series (Boxster, Boxster S)
Massive blue smoke at start up and intermittently while driving. Funny thing is though that the smoking seems to go away after I've driven the car long enough to let the ECU adapt. The car seems to drive okay after that point but not great. So thinking that the issue was fixed, I tried to clear the check engine light by disconnecting the battery and then the check engine light comes back on and smoking starts happening again. The car was intermittently squealing yesterday. The squeal would come and go at different speeds. The car is also idling rough. It seems to be dipping down below 8000 rpm. I can smell a faint smell of burnt plastic/rubber. I am getting the 1124 O2 adaptation CEL codes. Thanks for the help. Any advice is greatly appreciated. -

I just replaced my AOS also and the new unit seems to be shot already as well. Does anyone know what could cause an AOS to break so suddenly? What else is going on? -

Thank you very much for the response. I would imagine that Porsche would not recommend such a practice but what would the mechanical implications be of running at such a reduced temp? Also how would such a measurement be taken? Would there be such a considerable effect on the hydraulic forces at work within the transmission given that cooling fluid that cools the ATF is the same fluid cooling the engine and as such gets heated up rather quickly? I.e. there seems to be a small window of time where the valve would be closed (I didn't buy a boxster to drive around the north pole. :P) Also 15 degrees C is a rather large difference (60 degrees F.) I find that number hard to believe. Did you mean 15 degrees F? That would make a little more sense if speaking in terms of the range of temperatures (i.e. the mode in statistical terms of temperature readings.) Like I was saying the average operating temperatures would not seem to be hardly impacted at all.) I am going to replace the part since the local dealer happened to have one in on hand and I'm $60 too impatient to wait for the same part from the OEM supplier off Pelican. It's $80 at the dealer $20 online.

Would there be any reason why it would be a bad idea to bypass this valve altogether, letting coolant run constantly through the heat exchanger? I can get the part from Pelican for less than $20 but its a nightmare to try to get to it.

Coolant Disc Valve Failure
carlosvquezada replied to xflyboyx's topic in 986 Series (Boxster, Boxster S)
I don't see any way you could get to this part from the top engine access. Am I missing something or can you offer any advice from your experience? Thank you. -
Here's some pics and video of the problem. Any advice?
-
I can clearly see water leaking from what I believe is the coolant shutoff valve, i.e. the valve on the driver's side of the tiptronic transmission that has a lever that i believe controls coolant flow to the transmission. Does anyone know the best way to go about removing and replacing this part? also if anyone has the part number that would be greatly appreciated. 1998 Tiptronic, recently replaced 2.5L with 2.7L after IMS fail, recently rebuilt transmission (damaged torque converter)
-
I hope you don't mind me jumping onto this thread, but I have a related issue and need a little help. I have noticed a steadily rising running temperature for about a month and finally last night I got a nice steam bath from the back of the car and all my coolant dissipated. I can see water leaking near where I am guessing the cooling system enters the tranny. (tiptronic btw) Any ideas what may have caused this or if it might be symptomatic of other issues besides just age and the car being driven like a Porsche? About 14,000 miles ago I had the tranny rebuilt (heavily damaged torque converter) and replaced a 2.5L with 2.7L after IMS failure. Pedro Hi-Flow intake, and Crios exhaust mod. I attached a picture of where it looks like the water is coming from. Any advice as to getting to that hose would be appreciated as well. (i.e. how difficult is it too remove that lever that's sitting in front of it? looks like a B) I'm recently unemployed so I have the time to diy and not the money to take it to a shop. As such your comments are very much appreciated. Thanks

Sounds like my engine has rocks in it...
carlosvquezada replied to carlosvquezada's topic in 986 Series (Boxster, Boxster S)
Engine is toast. :( Any advice for where to get a new one?
