It's on a machined flat on the inlet side, to the right of the engine mount.

Usually covered in rust or gunge though, so use a wire brush, possibly some Jenolite and a strong torch.

theres a machined flat to the left hand side of the mount if you were stood looking at the engine from the inlet side but this has no numbers llike the ones i am looking for, its so frustrating took ky engine out today and stripped it down ready for a turbo conversion guna be gutted if its a high comp engine thanks
