whistle and knock under the hood - Toyota Sprinter Trueno, 1.6 L, 1997
recently, at 87t km, the belts, roller, tensioner, oil seals and VVT clutch were replaced.
after replacing the whistle was gone. all the same it was as I thought in the belts. and the clutch was in good condition. did not throw it away. left in reserve. they thought about her knocking. we will look further.
