Vanos rattle and seals

Hey guys,

So about to do the vanos repair on my m54.

I notice that I'm burning a bit of oil, wondering if the seals could possibly be what is causing the loss of oil.

Let me know what you guys think or if there is anything else I should check while doing the seals.

Thanks

Jrat

A couple places to check:
> Rear main seal (check rear bottom of engine, see if oil seepage there)
> Oil filter housing gasket (check engine block behind oil filter for oil)
> Oil pan gasket (check for seepage at bottom left front of engine)

I'm assuming you're replacing the valve cover gasket while you're in there doing VANOS.

Replacing the valve cover gasket at the same time.

Are you sure you're burning oil? Or just losing oil?
In addition to what was mentioned above, if you haven't replaced your CCV system, then it needs replacement, especially if you're burning oil and not leaking it.

As for VANOS seals, I did them when i did my valve cover gasket. You don't lose oil through them though, just engine performance.
