Almost sounds like the dreaded rod bearing sound on the S62, but I can't remember ever hearing of the M62 having that problem.

That one is really far gone (judging by the sound of it) but when they first start to go, they don't sound like that.

There are only so many noises that can come from the bottom-end.

I'm not saying it IS rod bearing noise, simply that it could be.

However, another thing to check is to remove your belt and see if the noise goes away. Which would indicate an accessory issue.

Oh - maan,

I can hardly hear the noises.

1st one, I'm gonna guess sway bar linkage. Is it noisy only when going straight and goes away when you turn -even slightly? The sway bar is only loaded up when you turn. When you go straight, it is "free" and a loose joint in the linkage can bounce around and rattle.

2nd one - I can't hear is very clearly but I'd guess the cat convertor is rattling. The noise doesn't match engine speed directly, so that would rule our bearings (rod, crank) and cam noises. Those would tick on every single rev.

yeah so the first is tuns out to be play in center drag link ...
thats going to be replaced...

second still unidentified...

i have huge doubts about my cats ... i know previous owner replaced them ... but with what part... when changing clutch i looked in to them ... the cats looked clean

I think my car has major power loss on low rpm line

I used to have another 98 540 before with 290 000 K and that thing was picking up way better
I got this one cuz its in better shape with lower clicks ...
recently I changed clutch, valve covers, intake manifold gaskets , sparks, new fuel filter and this thing is still not as fast as previous 540 i had ............ which makes huge disappointment

Honestly I dont know what else to think of... there is no lights on a dash , engine is smooth and quite but it just doesnt kick in the way it should

Im thinking to delete my cats ... maybe that is the cause ....

ANY TIPS / IDEAS IS VERY APPRECIATED

What year is this one? I think the Vanos motors are supposed to be slower?

Am I right saying this - the noise is more like a rattle than something that is directly "connected" to the engine speed.
