    SB 400 oil coming out bolt hole

     



    I just finished building a 400sb for my Blazer. Right next to the fuel pump on the front of the block are 2 bolt holes. When I rev the engine, oil spits out of the upper hole. Should there be a plug there or is something really wrong? I also get a blueish black smoke out that banks exhaust at first but it clears as it idles

    Install a 1/2" X3/8" bolt there. That hole is used to hold the fuel pump rod,used with a longer bolt during assembly.Brian

    I just fold a pic of the front of a bare block where it looked like that hole went strait through to the fuel pump rod lol. I have some of the 3/8 plugs that go in the rear of the block above the cam shaft. I'll try them tomorrow. Thanks Brian (my names Brian too, WTH! lol)
