The P6 has always sounded a bit exhaust-y. I initially put that down to a small hole in the ancient rear silencer, but further complaining and investigation led to the conclusion that there was also a leak near the manifold. Normally, this means a holed gasket.. or a broken stud in some join somewhere.. either way, not the worst job in the world but certainly one of the more annoying.
However, after an afternoon of removing 16 of the finest rusted-up 1/2″ British bolts, I found this:
I think it’s supposed to be an exhaust manifold. It has the consistency of Swiss cheese, and there are four or five good bulges in it. I didn’t realise cast iron could do that, but apparently – if made in Birmingham – it can.
