1990 F150 5.8L leaks oil from breather tube...

[WrenchMonkey]

Anybody know why?

The tube runs from the top of the valve cover up and into the upper manifold. There's a rubber bushing where the tube pushes into the valve cover. That's where the oil seeps out. Well, more than seeps... "pours" might be closer to the truth...

Anybody help?

Thanks much!

Robert

check the vac line that goes in the back of the intake and see if its plugged its been some time since i had a ford but im almost sure the other half of the pcv system goes ffrom the valve cover to the back of the intake (near the firewall) good luck
