Hi Jim, ok more revealed with the engine running issue, seems the cambelt has skipped on three camshafts, only the o/s inlet one is correct!

 

The worst one been the os exhaust been two teeth retarded, which explains the odd fuel firing down the exhaust on that side, the other two camshaft been one tooth advanced!.

 

You have pm matey

Does the engine even run in that state?

No not now, cannot fathom yet how the belt has skipped seems tensioned correctly, will see what tomorrow brings.

Its just my luck!

Jeff could that cause a strange miss fire on one bank If one side was out on the timing?

Problem with cam timing errors is it messes with the 4 stroke cycle which can cause firing down the exhaust as the exhaust vales are not closed completely, or open too soon which causes poor gas compression.

 

Generally though if a single camshaft timing is incorrect it should effect each cylinder on that bank the same but in practise we have found this is not always the case, most likely due to different wear rates on the cam lobs and or the valve seat differences, misfires are not the same though.
