    Default Cleaning engine block after bone and hone and paint

    Hi lads,
    another newbie question... I got the block back from machiners who bored and honed , depressed, and fitted new cam bearings..... being a newbie over the weekend I cleaned the outside and painted it..
    but after abit of reading on the net and talking to my mechanic, I should have cleaned the block.
    plan of attack is:
    clean block with hot soapy water (dishwashing liquid) (whole block, with a wire brush clean oil galleries etc)
    hose down, repeat , blow dry with air compressor, then cover the bores with atf fluid, and wd40 oil holes.

    on the right track?

    You need a pressure washer, get into all the oil galleries, every little crevice. Then hot soapy water with pipe brushes inside the oil galleries again and blowdry spray bores and the lot with WD40.

    Then do it all again another 2-3 times...

    Scrub bores with warm soapy water. With a toilet brush. Then believe it or not put some ATF Oil on a rag and wipe your bores down. Then repeat. You wouldn't believe how much hone dust the ATF picks up. When your bores are clean you should be able to wipe your finger with a clean rag dipped in ATF and have no grey residue. It will also stop bores rusting until rebuild.

    And prepare lots of bandaids for bleeding knuckles.
