Definitely cut and get the breather nipples off the baffles.

Your evac hose is already Off/disconnected at the header and muffler system, so that is not Back pressurizing it.

Forget about hooking up a vaccum test port at the fuel pump block off plate. You dont have any vacuum. You have positive pressure. The leaks may be helped or stopped by sealing the breathers and reducing the nipple length to get them off the baffle plates.

Start there, if you still have to much positive pressure, oil will come out of the filters on the breathers. Then, you have Bigger problems, loss of ring seal or leaking head gasket.



Leaking head gasket just caught my attention...what is a sign of that? how do I know?

Oil in the coolant, coolant in the oil, low coolant, high oil level, bubbles in the coolant when running, leak down tester could pick it up, Coolant pressure tester would definitely pick it up. Let the car sit for a few days, then crack the eng drain plug. Water ( or milky stuff ) will come out first if you have coolant in the oil. white exhaust smoke. - all in no particular order.
