White smoke

I had to get the valve stem seals replaced. $5000. Apperanly the wrong oil was used and caroded the seals. I bought the car used. The insurance had to decide whether to repair or replace engine. Cost was not much of a difference. They went with repair. Luckily it was covered by my warranty. Same isues ocured with white smoke. Embarrassing and annoying to others when at drive threws.
