It was time to get back to the Lotus Cortina and tonight I decided to get the new Piper exhaust manifold fitted. It comes in three separate parts. I assume that if it came in once piece you could never get it fitted due to the thermostat housing being part of the cylinder head casting on the Lotus engine. (As is the inlet manifold)
This is a four branch manifold that goes into to one collector box, so the first two branches and joined together, but the third and fourth branches are totally separate. The trick is getting the two joined branches of the manifold onto the studs while making sure that the two separate branches fit into the collector box all at the same time. Not easy!
Needless to say, it was quite a struggle and a considerable amount of swearing and cursing was involved! I was just about to give up and ring Piper to complain when all of a sudden it all twisted into place and slotted into place.
The next mission was to get all of the eight nuts tightened up with very limited access. (Especially the ones behind the thermostat housing) However, eventually they were all tight and I had to admit, the new manifold looked beautiful! 😊
