    Gaskets.... what a pain!

    Is there a "Best Way" to remove old, stubbern gaskets from the engine cases? With my exacto knife I have to be careful not to scratch the soft aluminum of the case....

    If you are like me, with crappy finger strength and stability, razor blades are dangerous.........

    I'm sure there are tips on better solutions in our community mind. I have never had to approach this beyond the front engine gasket, which was just a swift and careful use of a good oil to inch it off.

    there are easy to take off

    you need a chair your favorite drink and some gel paint stripper and a brush

    clean the mating surface of loose gasket chunks

    brush a wet coat of paint stripper on the gasket to be removed

    sit down in the chair and have a drink for about 10-15 mins

    lightly scrape off whatever comes easy

    put another coat of paint stripper on

    sit back down in the chair for another 10 -15

    clean the rest off

    this way you cant mar the mating surfaces

    You could use gasket remover too but it is just the same thing as paint stripper....

    Ya murray's got it, also wanted to add a few
    razor works good but be careful to not cut yourself, sometimes when the razor breaks thru a gasket it likes to attack
    paint stripper works fantastic. the engine cases are painted silver and id recommend taping the edge of the mating surface and paint to protect it, and be very careful w the paint stripper

    it's gonna be messy no matter what, so take care to protect your internal components.

    yes you may need to reapply twice, 3x, even more

    i used steel wool to prep the surfaces after paint stripper, but it made little wires get everywhere. I tore down the motor completely anyway so it wasnt a problem, but stay away from steel wool otherwise

    after steel wool, a little carb cleaner on a rag to remove residue

    def recommend my favorite tool, beer

    A mechanic friend told me to use a sharpening stone that had never been used for tools for final cleaning of the mating surfaces. Keep it flat to the surface, use a circular motion and dip it in water occasionally to clean it.

    Of course, keeping the debris out of the engine is an absolute must. I have a toilet paper holder screwed to the shop wall where the tools hang for when I need a small, clean wiper right away and use pieces of toilet paper to block off any passages to the inside of the engine when I am cleaning off gasket material.

    Good advice ~ the paint stripper. And use a very blunt scraper in a relaxed manner . Don't be hard on yourself and the edges. Yes, the favourite beverage will ensure the calmness needed.
