The noise is called 'ping' and is due to the gasoline exploding before it should. Could be carbon buildup in the upper cylinder or timing error. Get a tune-up and use higher quality gasoline and some upper cylinder cleaner.

I have a 425 CI 7 litre Cadillac V8 in a 1979 Diamanté. Once the engine is up to temperature a rattle like noise comes into the engine under acceleration. The noise goes when the throttle is


You need to find where the noise is coming from. On the top could be lifters, valves or low octane gas causing a ping. On the bottom could only one thing. Rod knock. The bearings for the pistons and crankshaft are worn.

What causes a rattling noise in my engine when i hit the accelerator?


"Rattling" is normally due to one of two things:
  1. On heavy acceleration, rattling is usually due to low octane fuel.
  2. If at all times, it can be due to low oil pressure.

    Rattling can also occur if the engine timing is way out specs. This will normally be accompanied by a substantial loss of power on acceleration.

Loud squeaking and rattling when you accelerate after a stop


Is the underside rusty? If so, take it to a qualified welding and autobody repair shop to have new metal welded on.

Your symptoms sound like the engine or transmission mounts may have deteriorated.

I think you might need to ask someone to throttle up the car and you look underneath to try locating the rattling noise. Don't forget that this model runs the exaust pipe in front of the motor so it might be an exaust rattle as well??

Rattle when accelerating


had the same issue, had someone look and it seems the noise was caused by heat shield being loose covering exhaust system. Have that checked out.

Rattling sound when accelerating on 2007 Forester


On mine, I got under there and there are rocks rattling in the heat shield. There are factory made holes in it, and the rocks sit in there like eggs in a carton and rattle when the engine hits a certain vibration frequency which is basically when it is at a stop light or idling. The repair shop wanted to charge to cut them off but I think I am going to drill bigger holes so the rocks fall out, as they are pretty tiny.
