Default Cam Cage

My wife's Legacy recently went into a dealer for an oil leak. What resulted was them keeping the car in order to replace the cam cage(s) which leak in 13' models. I apologize if this isn't the right place for this question but I cant seem to find an answer to what a cam cage is and why exactly thinner oil would cause the issue.

When they say cam cage they are most likely referring to the cam carrier.

2nd picture down the RED image is the "cage"

If you are using the a oil within your vehicle specifications "found in your manual" Thinner oil should have nothing to do with a leak. A leak in that area could be a gasket problem, a machining issue with the carrier it self, or faulty oil seal around the camshafts.

My left side cam carrier leaked after my short block was replaced. Currently in for repairs but I assume it was the gasket.

Is bigger than yours.

There is no gasket, just 3 bond and a couple of o-rings.

On early FB motors there may be a leaky threaded boss (unused) on the left front cam cap. I think they stopped drilling and tapping it by 2013 though.
