It’s really caked on there. I’ve tried a plastic scraper I made, a copper scraper I made, and a razor blade. The first 2 aren’t really working, the razor blade is kind of working but is also scratching the surface, which I know is bad. How bad of a scratch do you need before you get a leak? I know there is a gasket remover chemical they sell, but I don’t have any at the moment. Are there any other chemicals or other methods that will help remove it, please? |

You could spray a bit of carb or brake cleaner in a cup then paint it on and wait for it to soften. Try to just chip away at the gasket. Slow but sure. Hint when you put it back use some 3m to glue the gasket to the pump. Put the bolts thru the pump to be sure they line up. Then put run a little grease on the gasket that is going next to the block. Next time the gasket will be on the pump and not the block. Work on most any=of that type of gasket.

Hey Johnny, while were discussing cleaning gaskets off what is the best way to clean it off a block deck, the headgasket left residue on my block and on the top of the cylinder sleeves, scotch brite pads will not take off the "little dots". |

a wire wheel with a 1/4" shaft chucked into a die grinder or the roloc discs work on most anything BUT be careful of the residue from the roloc discs , there are many TSBs about it all the residue which is like a very fine powder must be removed prior to reassembly or bad things will happen to the engine , very quickly |

Cordless drill with a wire wheel attachment works pretty good if no air available. Wear safety glasses! |

Once you get all the gasket material removed, use Chemtool or Brakeclean to remove the last of the residue on the surfaces to be sealed. Both sides. On the head surface and the oil pump surface. It insures a good seal. Silicone and gaskets do not like to seal over oil or grease |

Now when I go to assemble, do all these blue "paper?" gaskets for the oil pump/water pump, etc need to have any type of sealer added? like RTV |

For a head gasket no. Only just clean it with the Brake clean or Chem tool. If its like the oil pump yes just a very little. The gasket does the sealing. The RTV only holds it in place till you can mount your part. And use oil resistant/hi temp. And make sure that every Iota of old material is removed from the head surface. Or you can be doing it again. Do you know how to torque it down? Once you have torqued it down. Start again, and if get even a minor change in torque. Do it again. Don't change the amount of T. Just make sure on your repulls. It does not move anymore. If it does go through the process till it does not move. Sorry I can see what I want to say, but my fingers are in resistance. And run a tap through all the head bold holes before starting T. |

OKAY??? Is a wire wheel too rough? After using it for a couple seconds I am noticing "pits" and little chunks of metal missing on the top of the cylinder sleeves? Ignore the dirty cylinder walls.

I was going to say something about being careful with a wire wheel on head gasket surfaces. It can remove metal, which would of course be bad on these critical surfaces. But chunks is not what I'd expect. Don't know what to make of that, other than to not use the wire wheel any more. Maybe try a Roloc disc or just some Scotchbrite by hand. |

Im at a loss, it doesnt seem possible..... I mean the wire is somewhat flexable and this is a huge chunk of aluminum. EDIT: Maybe it was there to begin with? and the old headgasket was just filling the void, and the wire brush removed those bits???? Im just theorizing Edited by chads4dr, Jan 29 2010, 07:03 PM.
