Hi all - appreciate this will be hard to answer but I've got a blow on my 2007 987 (60k miles) appreciate it could be any part of the system but what sort of bill might I be looking at (I'm taking it to a Porsche specialist).  Thanks for an indicative ideas / data points - thanks!

its possible the the captive bolts between the manifolds and the rear boxes have rotted (they all do it to a lesser or greater extent) - usual solution is drill out whats left and replace with regular nuts/bolts - can be a tricky job but a good indy will have done it a number of times and be able repair with relative ease - have known it done for about £200.

Good luck with that if that's the case for £200 .Did  mine, drilling out , and if asked would I do it for anybody, ......minimum would be 40 gold pigs and twenty hours alone with Raquel Welch from back in the day when she was being chased by dinassaurs, I would have to think hard and long,,,,

I don't think it's that big a job... with the right tools. 

I've previously removed these on a couple of Boxsters now. 

Best thing that can happen is that the pressed bolt snaps on trying to remove it. A set of Irwin rounded nut removers are a great thing to use if there's not much left of the original nut. 

If they do snap off, get a MAP gas torch (relatively inexpensive) and heat up the studs until they're red hot then hit them with some freezer spray. It basically shocks the stud and breaks off corrosion. 

Next, reheat the the stud again until red hot. Then, use a small socket that fits on the top of the remaining stud but does not slide over it. With a number of extensions on the socket, give it a few knocks with a hammer and out the stud pops. 

After you've removed them replace them with stainless steel bolts and washers but a brass nut. Using a stainless steel nut can lead to galling - the bolt and nut welding themselves to each other.
