    Default Renault part guru question

    I'm wondering if the bare 2.2 Dourvin Petrol block is the same part number as the 2.1 Diesel engine block?

    I've found that the diesel liners are alot stronger than the petrol ones a d if they fit they could be bored out to fit the 88mm pistons.

    I don't know the answer to your question but when I worked for Perkins Engines I discovered that they had made a diesel version of the Rover ex Buick aluminium V8. To stop the pots from pushing the rods and thus the crankshaft out of the bottom of the block they had to insert a BIG strong additional bolt-on layer of material between the bottom of the block and the sump.

    No luck, these are the various part number evolutions for the blocks:

    J7T
    7701 463 366
    7701 463 101
    7701 464 722

    J8S
    7701 463 297
    7701 463 015
    7701 463 298
    7701 463 647
    7701 464 723

    The blocks in the pics are quite different in nature as well, the diesel J8S block having a good number of reinforcing ribs.

    If you made life easier, it would probably become very boring.
