P38 4.6 GEMS has developed a metal clunking/tinny noise when accelerating (soft or hard acceleration). Can be loud and can sometimes not happen at all but my mechanic has given up looking for it.

The noise seems to be coming from the central front end area. Any ideas guys?? Cheers.

Flexi plate if it’s a auto is my guess,

Thanks. So flex plate is gear box out yes?

Might be as simple as a loose exhaust clamp ,,,, tinny sound,, or the exhaust hitting the body or cross member .Heat shields is another rattle point

We did look at the heat shields and the exhaust...so...flex plate looks like the winner, I do have a gearbox leak so this all adds up. Bugger.

Worth checking first before taking the box out,would expect the noise to be at the back of the engine if it was the flex plate.

Remember to check UJs with one wheel from each axle off the floor

And if there's little play grease them, they may be dry.

Get a rubber hammer and thump the cats with it.. or use your fist when its cold. if the inside of your cats are breaking up it will start to sound like gravel in a can.

I assume you had a listen with a mechanic's stethoscope?

Wouldn't flex plate be at rear of the engine? Got a video of the noise?
