The valve covers are almost guaranteed to be at fault. The baffling on virtually all aftermarket valve covers are garbage compared to OEM (except the THPSI ones, they’re solid) and I’ve yet to see Weapon X make anything properly thought out unfortunately. If you reach out to MM I believe he’ll suggest a small restrictor that helps but doesn’t fix the valve cover design issue.

Also, obligatory post about your coolant being low lol
