What do you guys use for copper head gasket sealer? I used Permatex copper sealer and it was gone, except for hints of it directly under head bolts where the most squish was. ------------- 2-8050 1-7080 6080 D-19 modelE & A 7040 R50 |

The engines that I've had copper head gaskets on, I've used O-rings to seal the water and oil passages and fire rings on top of the sleeves. Nothing on the copper gasket itself. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

Yep, fire rings on sleeves, since there are no grooves for o-rings, dont they get smashed down to nothing? ------------- 2-8050 1-7080 6080 D-19 modelE & A 7040 R50 |

| I have used coper coat at the most and that’s it. Chances of it seeping a liquid are high |

The holes in my copper gaskets are large enough that the O-ring set inside of the gasket and when using a .090 gasket with .125 O-rings they squash down to .090 ------------- If it was fun to pull in LOW gear, I could have a John Deere.

| Hylomar rubbed all over the copper gasket on both sides is about all you can do. |

I've always done the old trick of aluminum paint on headgaskets. I honestly think it prevents leakage better then copper coat - taken apart many things with copper coat that weeped - clean it up and use aluminum engine paint on the used gasket, put it back together and no issues. |
