C6 pulls left after new oil pan gasket

2008 coupe had oil pan gasket replaced. Upon leaving dealership it appeared to pull to left. I did not have opportunity to drive car for approx 3 weeks and drove approx 100 miles. Car pulled left on every type road it was driven on. i called dealer and they scheduled appointment to re-check alignment they did when gasket was changed. They told me the cause was that right front tire was 8lb higher than other tires. I disputed this because I had checked the pressure before taking it for re-check. I asked if car had been driven and was told no. They called back later, said car had been driven, and everything was OK. Car pulled left upon leaving dealership but they were closed. Took back two days later on Saturday. They rechecked tire pressure and I took a mechanic on drive. Again car pulled left everywhere we drove. He suggested that tires were tracking on road even though we drove streets and highway. He then suggested that since the car had not been driven for a long time (2 1/2 weeks that maybe the tires developed flat spots (?). After being in the left of three lanes and pointing the car to the right, the car went all the way to the right edge of the right lane and then tracked left across 3 lanes again. Now his suggestion is that maybe the left tire went bad and they want to switch the right & left front tires even though the are uni-directional. I called Good Year and they said to absolutely NOT run the tires in the wrong direction. Car has 10,100 and has never been in any accident and only driven by myself, son, and brother (when I was with them).
I understand that they had to lower engine cradle and loosen or remove tire rod when changing the oil pan gasket.
It seems that what ever they did when changing the pan gasket caused the pull. I've also seen articles on steering wheel sensors not being correctly centered /adjusted that can cause this issue.
