I did not replace intake gaskets, yet. It’s starting to need a rear main seal and I’m hoping to make it through this year without messing with the engine. I want to be 100% driveable before I hop it up next winter.

No codes yet. That also makes it weird for me. The only code I have ever gotten was when I forgot to plug the peddle in once.
