| Post subject: | Weird J20A sound |
Hi Guys, I'm having a strange problem with my J20A in my 2002 GV. It has developed a strange sound with the engine running. It is RPM dependent and is definitely in the engine and not in the gearbox. Here's a video of the sound. It's more higher pitched then the normal engine sounds and is more of a whirring sound. It hasn't affected the power output or driveability but is a little concerning if it's something on the way out. https://vimeo.com/94748653 Does anyone have an idea of what it could be? Thanks. |

Temporarily remove the accessory drive belts and see if the noise stops - whilst you have them off - spin the tensioner, idler & fan pulleys by hand - any roughness or noise is an indication they are on the way out. If the noise stops replace the belts one by one. |
