Q: Loud noise from engine.

asked by on

I hear a loud noise from the engine for only a few minutes when the car is started. It runs normally after that.

This is caused by the timing chain tensioners in the engine are bad and they would need to be replaced with new chains and tensioners. On some of these vehicle the camshafts may need to also need to be replaced with all new camshaft gears to fix the problem completely.
