Camshaft failure

John Mason · 06-19-2009, 12:46 PM

On a similar note, I pulled my SS motor out to exchange for a summertime bracket motor. It has never seen anything but Gibbs XP3 except for 3 heads up runs where it had XP0. The pan had about 2 cups full of sludge that felt like cam moly lube mixed with oil. When rubbed between the fingers it disappeared. The bearings were perfect but the sludge concerned me. I called Hetler, who said he has seen this with those using XP0 after other Gibbs oils. He felt it had something to do with the additives in Gibbs oil.
Any other experiences like this, or comments?
