Mein Auto: bmw x5 4.6is
E53 M62 Rough idle Ideas changed timing chain

wonder can anyone help.
Have 2003 4.6is 130k , The timing chain guides Broke, cost to get fixed 1000s more than the x5 is prob worth to fix no choice to change them myself.

Ok stripped back front of engine , and put on new guides and changed chain while there

Built back up engine and started car .. grand difference in engine noise seems a lot smother and no tapping noise coming from engine under start up in the morning.


Right my problem is while building back up engine we where not sure which vacuum pipe went where and have one small pipe not connected

Car is driving away but at idol is a little rough but once you rev , roughness go's

Has anyone got a layout for the piping for the M62 engine or ideas ?
Have checked manual but not really clear

on another note .. just curious .. what would happen if the timing chain was out by one link between sides on the V8 ?

was interesting being that far into an engine , need help putting it back together now

Also check sparkplugs. If you leak oil in the well around plug it runs rough.

First picture is the hose issue? Thin one? braided one? Give me a bit more detail I can take a look under my hood to compare.

What is second image. Is it the random electrical connector that goes nowhere ?

High thanks would you please ,
Its the black plastic pipe I am holding in the pliers its stiff plastic pipe not like a vacuum pipe its a bit bigger than a vacuum pipe in dia , but its made from stiff plastic

I am having to pull it up from underneath the water hose seems to want to sit under it

it is coming around the side of the engine itself

and seems to be shaped coming around the side to the front of the engine

electrical connecter must be from a light or something on that side ... I think

would aprecate it greatly .. thanks

hi

sorry have not been about in a month
thanks veryi much for your photos

ok yes right see in your second photo the hard plastic black pipe under the silver one

this is the type of pipe .. right that pipe you see there must run from fuel tank to the front of engine and hooks to a unit just mounted under the big thick rubber water pipe shown in your first photo.

It then runs from there to cross the front of the engine to the throttle body

I have that its grand

but there is a similar pipe same hard black plastic which comes from the RHS of the eingine down low and comes around underneath the unit the pipe shown in your second photo connects too ... underneath that water pipe shown in your first photo

mine stops here and I don't know where it should connect too

hope I am making sense
