Schematic diagrams 270cdi

[rony2rip]

Hello there, does anyone know of or have a link to a schematic drawing for the ML 270 Cdi engine. I'm particularly interested in the inlet manifold, and exhaust gas cooler etc. I've just refurbished the manifold, put everything together again with full success but a coolant leak has appeared where the exhaust gas cooler(I think), is attached to the head. Someone has been at it before me and I would like to make it good again, any help would be appreciated. Thanks.
