I have a strange engine "rattle". It's very quiet and isn't like anything
I've heard. it doesn't disapear above idle. Could this be the timing chain?

Jeep is 89YJ 4.2I, 293,000KM

 

Other than a roller, I've never heard a chain make any noise. It's
possible you may be hearing the fuel pump, but more than likely it's the
normal wear like piston slap, rod and main bearing knock, three hundred
thousand miles brings.

293KM.. not miles. no real way to isolate it? it burns no oil, loads of
power, lots of compression...
