    Default Engine cleaning

    I am looking for a suitable method,system,technique etc for cleaning up an 807 type alloy block, the motor has not been run for almost 20 years. the engine in question is a 125 hp 12g spec engine in very good condition if my memory hasn't failed me, i intend to put it in my Alpine while i rebuild the Alpine's engine properly

    27,

    The way I have cleaned my alloy Douvrin blocks is to don rubber gloves, spray with as many cans of degreaser as neeeded to cover both inside and out with a liberal coating, place in garden platic bag and take to car wash and clean there. This removes oily outside/inside residue, leaving the block clean enough to work on the bench at home at your leisure with turps etc and a brush minutely inspecting crevicesoil passages etc.

    I have used plastic media blasting after Export degreasing. Came up nicely.

    Also I employed a good few rubber gloves and fine brushes/picks plus compressed air to clean plastic media and oily residue from blind holes and long/narrow oilways.

    What is this plastic media you mention, Addo?

    Wet bead blasting does the trick too. This is the way they clean up old carbies to bring them back to sparkling condition.

    But you didn't mention if the engine is assembled or dismantled.

    If it's assembled, lots of degreaser followed by a pressure washer does it nicely.
