Re: Valve cover spreader bar

mechanicalman, I have used a flap wheel on a side arm grinder and LIGHTLY polished that entire rough surface. I must say it has worked beautifully. domano, you could try rotating the one bar that was causing you a problem to a different site to see if another bar would work there. If none of them work at that particular spot you could use a rotary grinder to open the hole on the bar to help the bolt tread properly. And I am a big fan of the Fel-pro steel core re-useable gaskets.
