What are these plastic fittings? They broke where they are pushed into the manifold. I have to try to order new ones but don't know what they are.
Crankcase Vents?
Thanks

Those fittings distribute the crankcase vapors evenly (more or less) among the 12 intake valves of the 6 cylinders. You can get the part numbers from EPC or a dealer can look them up for you. The "plastic" fittings are actually rubber that has hardened from heat and age. They are supposed to fit snugly over the straight pieces of plastic tubing. You'll need to replace all of them.

Thanks. Has anyone eliminated the tubes and vented the cc through a filter? I know they do that on the bigger trucks. The inside of the manifold wqas a little dirty.
