'88 G63B oil consumption issue/general engine questions

sorry about that, i try not to spam. this part is labeled as a thermo valve in the vacuum diagrams and web searches call it a ported vacuum switch
i took to the parts store and it seems to be a 3/8s pipe thread fitting which you were right about. here's the picture of the part
