Capri - Exhaust Manifold Flange

Owning a classis car means frequent maintenance and that is part of the fun! Maybe! The green Capri started to sound a bit like a tractor last week and a hand near the exhaust/manifold joint revealed an unwanted exhaust gas leak. If my memory is correct, the exhaust pipe had a very small crack in it where it fits into the manifold. So, off to buy an exhaust bandage and some muffler putty. getting the flange off wasn't a great problem but the two nuts are getting worn so I decided to replace them. (These pictures show the flange on loosely)



That was the hard part. I thought they were 3/8 inch UNC and they fitted the bolts at the local hardware store but on trying them on the car, they were not quite right. I tried numerous spare nuts but none seemed to be the correct fit. So off to the local bolt specialist & after a bit of trial & error decided the best fit were some metric nuts, about 5mm.  You never know what is on some old cars!
I wrapped the bandage around the joint, put some putty on top and then tightened everything up. After running the motor for about 10 minutes, it all seems good so we will wait and see after a decent trial run.
