I've got a 2006 Cayman S that I'm trying to swap exhuasts on. In the process of taking the old exhaust off, I managed to break one of the studs on the triangular flange.
The stud that is currently broken is the outermost stud on the passenger side manifold. I've had this problem before and I drilled the studs out. However, this one is angled in such a way I can't seem to get my drill on it at a straight shot, so that's out.
I've been using a torch to heat the stud head and try to hammer it out. So far it hasn't budged one bit. Can anyone give me detailed advice or tips on how to do this? I've searched and found that people were successful with this method, but I haven't been able to find detailed instructions. I'm also trying to avoid taking the manifold off the car. The bolts holding it on are rather rusty, and I'm not looking to break one of those, too.
Just as a side note, if I do have to take the manifold off, I'll have to remove the oxygen sensors. Will spraying them down with PB Blaster damage them in any way?
I've already called a dealer in case this gets too bad. But they are booked up and can't look at the car till Tuesday, so I've still got some time to get myself deeper into trouble.
Thank you in advance,
