6A13 non turbo Engine Rattle

[Jsa274]

Good evening all, I’ve owned a V6 Sport Galant manual for a few months now. I’m thrilled to bits with it but I’ve noticed that at around 2,000 RPM unloaded (ie freewheeling) there is a rattling noise emitted from the engine somewhere. A quick browse of the internet suggests the valves are a bit rattly anyway, but I wanted to see if anyone else has had this specific symptom. It does this in gear while moving and in neutral when stationary.

I’ve not had a chance to look under the bonnet in daylight hours yet to pinpoint the noise, but thought I’d get some insights before I do.

Thanks in advance,

Jamie
