No oil flow mystery

We have not tried a different filter, but hearing about that second plug behind the front cover is one of the things I was hoping to hear about. If they can forget to put the back plug in they can forget to put the front one. I'll have to pull the harmonic balancer and timing cover to see

Probably have to pull the cam sprocket to install the plug if it is missing. When you reinstall the timing cover, make sure you clean and dry the corners of the cover and pan really good, and use some sealer. The passenger side of the cover and pan junction is a pain about leaks.
