I might have a solution to the leaking oil cooler problem. However, I need a donor unit to strip in order to find out how the bottom plate is fixed to the body. It may be soldered, glued or crimped. I will need to destroy a donor unit to find out.
Does anyone have an oil cooler lying around which they wish to donate? I'll pay postage and if I manage to repair it you can have it back free of charge.
cheers
