Re: Valve cover breather bubbles aluminum?
Nick
The breather portion of the valve cover is a lighter silver than the actual valve cover (per your picture). The blistering of the paint (Your word bubbling) indicates a heat issue from the wrong type of paint used to do a poor job of repainting the breather. That low temp paint should NEVER have been used on any engine part.
It's obvious to a trained eye and knowing the poor decision to use a non-engine paint. It has nothing to do with the integrity or fatigue of the metal, it's a visual defect from the wrong paint.
