Belt or chain?

If belt, what interval?

Chain, so probably the most reliable bit of the engine.


Sumps leak like all BMW slant sixes.


Vanos isn't brilliant.


Water pump impellers fail, which cause the biggest problem: knackered heads and blocks. Which usually means an overheated engine is only fit for the bin.

Ok :y

Been offered an '01 525 which seems to run/drive fine but has breather issues as camcover gasket leaks like a seive...

Oil separator is obviously blocked up as the car idles beautifully with the breather pipe disconnected, but literally pours oil over the exhaust when you reconnect it ::)

Looking at about £50 in bits to fix that, and it needs a bloody good service, but it's clean and tidy, with a few age related marks, and absolutely no rust...

What could possibly go wrong ::)

The vanos could have that nasty metallic rattle till the oil circulates.

I take it they changed the design of the oil seperator, when I had an e36 it was vacuum operated. So when engine was running it was closed off then when the vaccum dies the valve would allow waste vapors into the inlet, a crude design

Make sure it hasn't blown the front or rear crank seal out if it's pressurising.  That'll render it worthless.

If the routing is similar to the M52 the breather can be accessed under the intake manifold by removing the throttle body.  Fiddly but doable.  Plastic connecting pipes get brittle with age.

Could be worse.. could be an M62 v8  ::)

Bottom of engine is oil tight... Only had a cursory look over it as original reason for looking was to diagnose oil leak.

Will have a closer look if I decide to proceed :y
