My advice is to take the gentle approach until that no longer has any chance of working. Keep your eye on the prize, which is a nice, quiet, great Pontiac engine. See if the engine builder will come to you and listen to it with his own ears. If this situation escalates, he may shut down and do nothing. Then a long, drawn out unhappy situation comes next. You don't get your car running properly for another year, You have to hire an attorney, You have to invest time, energy, in an emotional roller coaster that doesn't guarantee full recovery, if any. You may spend a year to get a $500.00 judgement that may take another 6 months to collect. It would be much better to have it diagnosed, repaired, and forgotten about, with a good engine under the hood. I hope you have a good outcome.
