Metal Flakes Found in Oil Filter

[ubii]

Well, I dropped off the car yesterday afternoon and got a call back from the shop today. They dropped the sump cover and did not find any metal debris, but did find what appears to be fragments of either the chain tensioner paddles and/or ramps, as seen in the photos below. This probably explains the noise that I heard the last several times that I started the car, prior to discovering the metal flakes in the oil filter. They plan on pulling the engine, so they can inspect both and then replace whatever needs replacing. Obviously, this will result in much more labor than what was included in the original estimate. The revised estimate is now about $5500, assuming that they need to replace both the paddles and ramps, as well as the IMS bearing, RMS, and clutch. This is worst case, as the labor will be a lot less if they only need to replace the paddles and not the ramps. Anyway, I am just curious how this compares to what others have paid for this work, in the past.
