So after having an issue with a cracked manifold which led to a destroyed converter, I now need to replace my engine. It started burning oil inconsistently since the converter went out and now it is burning a quart of oil every 150 to 200 miles regularly. I have already gone through the pcv valves and valve covers and found no issues. My only thought now is scored cylinder walls and/or stuck oil rings. I plan on buying a used engine from a fellow forum member and putting that in my truck until I have the time to rebuild my engine and put it back in. I searched the forum but did not find any threads on anyone doing an engine replacement so I will do my best to document everything so that it might help someone in the future. I plan on doing the swap in one weekend since I can't go without my truck so hopefully things go smoothly. If anyone has any advice or tips I would love to hear them!
