I did my valve cover gaskets a week ago and noticed that the 90* elbow that the hose from the intake pipe connects to on the drivers side valve cover is loose. Not terribly, fall out loose, but loose enough that you can just wiggle it out.
the area around it has sweat marks of oil but not not nearly enough to produce a drip. However yesterday I did a smoke test (for a different reason) and found that it leaks air pretty heavily.
Am I missing some gasket, o-ring, or other retaining/sealing mechanism here?
Can I just use a bit of FIPG on it?
