I have an M2 4 cylinder engine nearly rebuilt but at the last minute we have discovered we are missing a splash guard on the upper side of the back end of the main bearing. This stops oil leaking out the back of the engine (flywheel end). In most blocks, this splash guard is cast into the block. In my case, it is not. I do not have the required part. If anyone can help me, please email me and I will send a much more detailed description of what is required.
