    cleaning valve covers

    I was wondering if anyone had any tips on cleaning valve covers? I bought a set from the junkyard a couple weeks ago and have soaked them in a bucket of water with dawn in it and got a good portion of the gunk off of them, but there's still alot of oil gunk on them (since they're 30 years old and had 220k+ on them and the bolts were only hand tight, there was oil sludge everywhere on them.) I don't expect to save the paint (which is already 1/4 missing) but I would like to get them really clean so I can repaint the outsides (going cadillac blue) and get the gunk off the inside so I don't have to worry about it.

    Unless someone has an overwhelming reason not to (i don't care about the paint either), I was planning to use brake cleaner, scrub pad, and elbow grease on my spare set before I paint them.

    If they're not rusty, Easy Off oven cleaner. If rusty, drop them in a bucket of vinegar. Buy in bulk at Costco or the discount food store. Take them out a week later. Rinse with water and baking soda. They will look brand new.

    I used vinegar on a motorcycle tank and it worked magic.

    If you have a local machine shop they'd probably hot tank those valve covers for you for 20 bucks. It's one of those deals where its like how much hassle do you want to go through? If it's hot tanked they can clean the baffles out and everything. Then you can just pick them up and paint them and be done with it.
    csbuckn and cadillac kevin like this.

    They only have slight surface rust from me leaving them outside for a week (because apparently the only thing holding the paint on was thick oil gunk).

    you can see as the grease comes off, so does the paint. these are from a 1982 chevy van btw.

    Those need brake cleaner and a stiff bristle brush.
