Where is the engine number located on the 2.6? Can't for the life of me find it.

front side of your block on the right hand side, there is a flat metal tab as such that protrudes out, give it a clean up and you should have your block number... also while your there you can have a look on your cylinder head for your model number will be a M.... something M5 M7 M* M9....

You're a champ, thanks mate!
