So I ended up ripping down my engine, and was surprised at how bad the cracks were in the motor. both the head and block have cracks in them, and here's the pics of the teardown. The head I'll have to replace, but I'm having trouble finding a head that's meant for my year (2005 Merc 3L). Is there anything special or different for the post 1990 fours? Also, for the block, I'm thinking my best bet is to jb weld it and test it. The head will be simple, but doing the whole block will be a pain in the *** and will cost a whole lot more. But the cylinders look fine, manifold looks fine too, so I'll try just the head for now.
How come the middle cylinders have darker intake valves? do the middle cylinders run richer then the outside ones?
...on with the pics!
