Got another in a chain of UOAs on my '99 Suburban tow vehicle. This is the first UOA (but second fill) after replacing the lower intake manifold gasket chasing the coolant leak shown in the analyses. Probably not useful to anyone but posting it here to reference from another thread.

Thanks for posting. One thing I've decided to do is stop using engine oils with high sodium content. It is very difficult to easily see contamination improvements with high sodium content.
