Check out this thread, the heat exchanger might be the culprit.

cool thanks guys, I will document my adventure with this engine with lots of pics. Thanks for the help, we will be doing a compression test and removal of the bumper exhaust and tranny this weekend. I did more research and found that most people pinpointed the problems to 3 main things: the head ( warped or cracked or gasket )
or the Heat exchanger or possibly even a cracked block. I talked to some porsche mechanics here and they all claimed it's probably the head. Is there any way to know if it's the heat exchanger, or the head? or should I drop the engine and just take it to them and leave it in their hands? I really want to pinpoint the problem, either way I know the engine will have to come down : (

I think I'm going to work my way down to the problem. Compression test and the heads, if they are not the culprit then probably heat exchanger, and if that's not it...then I have no clue

With that mileage on the motor, I'd find a good used one.

I think you've got your order wrong way round - its a lot easier to remove the heat exchanger (located on the top of the engine), have it pressure tested and, if its OK, move on to the heads and coolant plugs.
If you use the search function theres enough reading to cure insomnia......

I agree with checking the heat exchanger first, since the techs have pointed to this possibly being the issue in other threads. If you find this to be suspect, also replace with the larger 3.2 S version.

Thanks again! I will remove the heat exchanger this weekend and have it pressure tested. Is there any way to tell that it's bad without having it pressure tested from the get go?

the mechanic told me to remove the engine already but I want to make sure of everything before I need to do so. Thanks guys I will take pics this weekend and post.
