Update, I went under the truck with intentions of installing the donut gaskets and to my surprise the collector bolts were loose!?
I cranked down on them as tight as I could before with a stubby ratchet so this time I tried tightening them with my 1/2” ratchet long extension and a universal joint.
Going to see if this cures the leaks if so I’ll return the gaskets otherwise that’s the next step. If it does I’ll probably apply locktite to the threads as well.
tightened while cold
Also noticed I have a pinhole leak by the y pipe (my mid pipe is welded directly to the Y cause it used to always leak no matter what)
*update - passenger side leak sound is gone, but driver leak is still there.
Who decided to put an o2 sensor right in the path of the bolt!
