    water pump gasket - baked on!!!

    I have never seen a gasket material so carmelized. The WP came off easy. Bolts no big deal, etc. But the gasket between the pump and the TC is literally baked on. Is there any chemical that will take this off easier? I can scrape, but I'm gonna be here an hour or so. Tried razor blades, gasket scraper, etc. Not making good progress. Have worked on lots of cars, and this one is by far the most difficult gasket bake on...

    thanks for any suggestions.

    There are mini sanding disks for this kind of thing. They can go on the end of a drill, if you don't have a mini air grinder. Lot of shops use them.

      thanks marquisman. Yeah, i have a dremel tool but don't have the little abrasive wheel. Should've thought of that instead of fighting the gasket for over an hour!

        Be extremely careful with any sort of abrasive. Its an aluminum timing cover. If you go too far, it will never seal and then you're into replacing the timing cover.

          My dad has an air grinder that I used when I replaced my lower intake gaskets. He told me the same thing gadget said and he also told me to use the most warn out pads on the aluminum stuff to help keep from going to far.

            Yeah, I just stuck with a gasket scraper. Actually, you can gouge with a scraper too. I had to use one of those paint scrapers that has the razor blade.

              true, but small nicks are easy enough to patch up. Wide low spots are virtually impossible.

                  I'm gonna call BS on that. He makes a good point but every single shop in the world uses scothbrite pads and die grinders. According to that guy not one engine should ever run again.

                  I usually use the little yellow finger pads on aluminum or remotely clean parts. Anything else gets brown cookie fever.

                    Also there are different grades of disks, I don't use the brown (coarse) on aluminum mating surfaces. There is medium (green ?), fine and extra fine (grey).

                        Since I was looking through my tsb collection, I came across these two. A bit more science behind this than the bitog post that I originally linked.

                        I'll stick with my 'bad juju' statement.
