Check this out. Had the same problem. Easy fix. When you pull up at the lights does it blow steam everywhere as your water drips onto the exhaust. Next step is the water gets onto the coils engine light comes on and it mis fires!! Anyway solution. As it is doing it when you look at the bottom of the expansion tank you will see the water dripping. The tanks had a weakness and have I believe now been modified. Take it off and put your fingers over two of the three pipe holes, then blow down the other. Wifes often good at this!!! You will here a hissing as the tank has a pin hole in. It comes out fast as the pressure builds. To remove the tank undo the air box (1 x 10mm bolt and the screw on the large jubilee clip) Then undo the two petrol pipe bolts ensure your engine is cold. You should need a seventeen mm spanner. Then just under the engine lid you will see a 10mm nut which you need to undo. The box then slide forward toward the middle of the car and then back in a fastion!!! Give it a good blow you will see it. If you really must get in the bath with it and do it under the water.
Now get another and replace it.
Good luck everyone..... j

Oil appears in the coolant reservoir bottle


Hi,

To my knowledge, most oil coolers would be In Front Right Fender for 1995-1998 Porsche 911 Carrera 2 and would look something like the image below.
966b111.jpg
Although I have strong doubts that your seals are needing replacement. Should they be worn out, defective oil seals would exhibit leaks that would be noticeable. Nonetheless, if you would follow the two hoses connected to the oil cooler, they would lead you right back to their entrance and exit points in the engine.

Oil mixing with the coolant and visible in the coolant reservoir indicates another problem, most probably head gasket.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

996 carrera leak from expansion tank


The shouting was over long ago. Like it or not, and for a multitude of reasons, had to develop a new 911 in order to continue producing one at all. Carrera faithful revolted over such radical notions as a water-cooled powerplant, a longer wheelbase, and more comfort. Power steering-how could it be? These philosophical issues don't really matter anymore, because the old 911 went out of production after the '98 model year, an all-new 911 appeared for '99, and that was that. So we're not here to debate the relative merits of the newcomer versus the classic. That battle is over-or will wage forever, depending upon which side you sit. But the question remains: Is the 996-platformed Carrera a great sports car in its own right? Only a year behind the wheel would tell us.

when water temperature rises it's an indication off a head gasket busy blowing or already blown.this would blow water into the oil. make sure you don't have the engine overheating. this could cause a number off other headaches. have the car towed to a good mechanic. do not use the agents because they will make you hate porsche. I take take it it has the flat six engine and will use two head gaskets on each side. I would order this and buy it myself. you will save money. give it to the mechanic who only does the labour. people think that when you drive a porsche there is money to be wasted. take care
