Rod bearings 1,2 & 4 look good, but #3 not so good. This engine has approximately ten race weekends sense it was rebuilt. Has anyone seen this issue?

I do believe adding more air exit area from the oil cooler will help with cooling oil. I’d rather not put exit holes through the hood, but wouldn’t mind increasing exit hole size in trunk floor. Was trunk floor exit not effective?
