Brothers, what should I do if the waste gas valve is broken?

Recently, the wastegate incident is disturbing. GM knows whether it is a design problem or a neglect. I'll give you a test method, which is also available in this forum, but I decided today by looking at whether there is engine oil in the throttle.

1, let me explain it in detail, that is, unscrew the clamp at the throttle door, then turn the trachea left and right to take it off, and then wipe the caliper that draws out the oil with a paper towel for later use. Take a good hand, lift the throttle off the net with your fingers, then hold it steady with your other hand, and the throttle will open. Then use the dipstick to probe into the next hole, all the way to the end, and take it out to see if there is anything on it.

2. If you are under warranty, go to SSSS. Although your waste gas valve didn't hear obvious air leakage, you can say that there is oil in the throttle, because the general maintenance personnel will advise you to replace the cover assembly when checking that there is oil in the throttle, and those with warranty can be replaced free of charge.

3. If there is no warranty, I suggest you replace it quickly, because those air leaks on the Internet are noisy, which means it is serious and the money can't be saved.
