What is the reason for the oil in the accelerator?

There is oil in the accelerator. Is the wastegate broken? There are many reasons why there is oil in the throttle. Not only the wastegate is broken, but also the turbocharger is broken, or the engine returns too much air under compression. The specific reasons are as follows: 1. The wastegate is damaged or normally open! Many cars have a wastegate connected to the valve cover, and the wastegate is connected to the valve cover and the throttle intake hose! If the wastegate is broken, there will be oil in the throttle, which will indirectly lead to slight combustion of the engine! 2. Turbocharger burns oil! Many car turbochargers burn oil! This is easy to judge. As long as the intercooler is disassembled and oil is found in the tube of the intercooler, it means that the supercharger is burning oil! If the situation is light, you can use it first. If the supercharger burns oil badly, it should be replaced! 3. There is also a case where engine oil flows from exhaust pipe, exhaust valve and one-way valve to throttle or water inlet pipe due to excessive return air under engine compression! 4. There are also some models whose rocker shaft screws are loose or fall off, which will cause a lot of engine oil in the intake pipe or air filter element, which will enter the throttle more or less! As simple as a van engine!
