And I believe that would cause the VVT system to malfunction since it operates off of oil pressure, doesn't it? And that chain of events would trigger the CEL cam timing codes since the cam isn't doing what the computer thinks it should be doing and likely damaged the VVT system inside by running it dry.


I would think they should have just replaced the VVT unit itself instead of everything that they did.


As an aside- Personally, if I had the recall done and afterwards they found sealant blocking (or partially blocking) an oil passage in the heads I would demand a new engine, and involve a lawyer if necessary. There is a 100% chance that lubrication failure did permanent damage that will (at best) shorten the lifespan of the engine a bit and at worse cause a major failure just far enough removed from the recall fix that you will be shit-outta-luck having them cover the repair when it does happen.
