Hi
Have just finished fitting a new exhaust manifold to a 2286cc petrol engine.
The manifolds, as you probably know, are both on the same side. There are 5 bolts on the 'top row' - one at each end and one in the middle for the exhaust manifold and two for the inlet manifold.
Below these, there are two bolts that hold both the exhaust AND inet manifolds in place. These bolts have a lozenge-shaped bit of metal on them so that they apply force either side.
Problem is..... I managed to tighten one, but the other one just slips, that is to say the lozenge spins round. The other one is fine, so I am probably missing something really easy.
Good news - at least the engine starts after manifold / carb reassembly and there aren't that many spare nuts left over.
There is a bit of an exhaust leak - what is the torque for tightening the (cast iron) exhaust manifold and the alloy inlet one? Have looked online, to no avail. You'd think it would be easy to find.... I have tightened them to a certain degree but didn't want to strip anything. Leak could also be coming from downpipe (disconnected fan belt so I can feel any leaks by hand).
Any help would be most appreciated. Many thanks in advance.
