Intake sucking oil

[4.0forlife]

Ive got an 88 comanche i just h.o swapped. The small vent line in the back of the valve cover that connects to the intake is being used to consume oil. The intake pulls the oil from the valve train. The valve cover seems fine even did cruisers mod to it but it still sucks oil. Any ideas?

Isn't there a fixed orifice (2.6mm) on that line?

I'm not sure its the same line from when i got the truck

Does valve cover front vent line go to air box?

I have one on stand by but i wasnt sure if it would play nice with the vacuum from the intake

[omega_rugal]

put it inline with a pcv valve

But the other ones the one thats transporting oil with the motor running theres a slight vaccum on the pcv side

Is that tube clear or partially clogged? Is it shoved down through the grommet too far? $8 will get you a new tube with grommet.

 

The tube from the rear of the valve cover to the intake manifold is part number BK 715-1365 or Dorman 46005 and comes with the valve cover grommet.

Ok i checked the tube. Its wide open and theres a lip on the end fitting that provents it from going to far in

Is it the original by chance?

Where is this oil accumulating?

I believe it to be the original but i stuck a clear piece of hose on the end at the intake and you can watch the oil come through into the intake
