Name this part/help it came apart!


Recommended Posts

So this popped off today when I went into reverse and went backwards and right. No idea why, maybe the tubing is too short. Lost a significant amount of power, luckily I was like 2 blocks down hill to get home.  Anyways I have no idea what it is/what it does. Seems oil related. IMG_3122.thumb.JPG.b25ed9a9caaf836edd440950a08f03cf.JPG

Thanks in advance, because you guys always come thru!

If that hose was all that came lose and it connects to  an oil catch can for crankcase ventilation from the valve cover, then it couldn't have caused any loss of power.  Did something else also come lose like the brake booster vacuum hose?

Best guess  its plumbed incorrectly with one of those hoses connected to the intake manifold.  To be properly plumbed one side of the catch can should be connected to the tube on the valve cover and the other side of the catch can is connected to the air filter housing.  you will need to know how the catch can is designed to plumb it correctly.

Here's a picture of how I installed mine.  If I remember correctly, that aluminum piece on your unconnected hose is actually a plug.  So the hose exiting the oil catch can isn't venting to anywhere.  You can leave yours plugged, or remove the plug and route a hose down by your brake booster to the ground, or route those fumes back to the air cleaner to be burned.
