I have just replaced my rear main seal because I thought it was leaking. Turns out that a bolt in the engine block is leaking and running down. Question is: Does anyone know what this bolt is for? It is located on the r/h side of the block at the back just where the turbo oil return pipe is.....
I tried getting in with sockets, extensions etc but not a chance. Looks like the turbo and up pipe has to come off.
