    Ok, I thought I had this beat with the new motor. When I assembled the engine I made sure to coat the intake bolts with RTV to prevent oil from making its way out through the holes but to no avail. A week since first firing it up, the first traces of oil are now coming out of the middle intake bolts. I have washers on them and used blue RTV. Any ideas?

    Thanks.

    Are you sure it's oil? There is no oil pressure in that area but usually what happens is the throttle shaft is loose in the base plate and fuel seeps out and mixes with dirt and it looks like oil. Just a thought.

    Use thread sealant, not RTV

    Definitely oil. Carb is new.

    I'll get some thread sealant.

    Thanks.

    Hello,
    Yea when I put on my edelbrock intake I did not use thread sealant. About 2 days after I got my engine fired up it started to pool up real bad.
    Then I put on some thread sealant and it has not lieaked since.
    Thanks
    Adam

    I used black rtv when I put my engine together. The blue rtv is mainly used for a water sealent and black is for oil.

    This was my first engine. And with as much money as I put into the engine, "BELIEVE ME" I made sure what the difference was. My engine doesn't leak a DAMN thing!!!!!!!!!!!!!!!
