Lower motor rattle
I have an 04 with about 90k. It's always had 10w40 synthetic oil changes, 5w40 in winter, runs great.
I've tried searching on here for answers but can't really find anything that helps. So here is what I think is a problem.
When I start my disco after cooking down, it hums like a kitten. After a 30 min trip or so, however, a sound from the lower engine/sump sounds like a metalic rattle; the sound a bolt or nut would make if it was floating around down there. Goes away when engine is rev'ed.
From experience, I thought it might be the cats, but they sound fine. I get a stethoscope and it's coming from inside the pan. I droped the pan and no parts thank goodness and no scrapings.
Could it be bearings anyway? Valves or rods? I know sound can travel in these motors. It not a horrible noise but it's not something my other rovers have done.
If any one might have a idea, that would be awesome. I could also take a recording if the noise if it helps. Thanks
