So can anyone provide me with a vaccum line diagram for my 1990 744ti? Or even more helpful, what connects to the small nipple on this part? https://www.fcpgroton.com/product-exec/product_id/14884/nm/1985_1992_Volvo_740_Turbo_PCV_Breather_Nipple/category_id/10
Currently mine is capped off with a rubber plug but I feel there should be a vaccum line there. If a vaccum line does go there then where does the vaccum line connect to, intake manifold? Also, how many of these are supposed to be on these volvos? Mine has 2, but the previous owner also had them connected with electric conduit so that could be wrong.
