Actually, it is a GM sourced LZ4 3500 engine that was used only in the 2008-09 years. The Honda 3.5 was used earlier.
Yeah but what the heck, never let the facts get in the way of a good story.
And even a cursory look at the orange can dissection shows it has no filter bypass which means it must have block bypass which Hondas don't use. Otoh, earlier GM engines do use block bypass. But it must be Honda's fault.
And I'm unaware of the the 3.5L being a top tier short maintenance interval engine. But being in a GM, it would make it their call. Owners manual says it uses an OLM which would be calibrated by GM. And the oil for Honda would have been an API SL/M 5w20. Hardly top tier.
As for the orange can, looks like typical orange can construction to me. The endcap centertube seal areas not shown so can't comment on them. No idea why the dome looks so cruddy. As suggested perhaps some longer trips at operating temperature might help. Think I'd run another short oci/fci and check again. Might suspect possible coolant intrusion if the result is the same.
