Had a code pop-up. Lean engine running. Mechanic diagnosed the worst possible case with the smoker, rear main seal. He said that original is trash since my car had less than 80,000 miles. He suggested redesigned version. Since I used to shop at URO, it was the first place to look for. I also decided to do the clutch at the same time, so I bought the rear main seal and clutch together and got free shopping. Goods arrived in 2-3 days in separate packages. After installing my mechanic cleaned the codes and now it runs like a charm. Will do business with URO again.
