Replaced the front o2 sensors the other day as I already had the truck in the air and had the sensors sitting on a shelf. I had the reinforcement plate off for inspection so made the job fairly easy.
Took out the thin dealership oil and put 20w50 in + lucas oil stabilizer. Also going to add a bit of at205 in there for good measure. Temporary measure to keep the freshly degreased engine from getting filthy again before I do all the seals. Spent a good couple of hours in there with brake clean, purple power, and water. I hate working on oil soaked engines.
Waiting for my aero kit to get back from the body shop... can't wait to drive the truck again and see if tightening the front tension arms at the subframe cured my clunking. Can't believe I did not torque them on initial installation. Or maybe they loosened. Yeah that's it, maybe that's what happened.
