The BMW 3 Series fuel tank cover plate is made of multi-layer materials, which may be bent due to different thermal shrinkage. The material of the outer layer will shrink more obviously, and the surface of the cover plate will sag, which will cause the tearing edge to melt the welding area, so that it will leak from the edge seam after refueling. To solve the problem of oil leakage, the whole oil tank can only be replaced.

If the oil pipe joint of the engine leaks oil, it can be used in? Horn? Wrap cotton yarn around the lower edge, and then tighten the tubing nut and tubing joint.
