Vanos problem

The other issue now is that if the oil feed
to the Vanos is or was restricted, and the
restriction is prior to the 'split' of this feed,
other side is to the Cams, then how long was the
engine run or tested in this condition ?

Even if it was for a few minutes only while
they diagnosed your Vanos noise, then your Top
end may well start rattling very quickly.

I would obtain some sort of undertaking on
the Valve Train given the issues over the
Vanos etc.

You certainly need to get it on the record.

I dont think they took a reading before the first start.... They will do all the test now. They also dont have a problem with replacing anything that needs to be done to fix it now, but if they miss anything I will sit with the cost later. I will push to get cams, gears and vanos replaced now but if they dont then your undertaking sounds like the way to go if they agree to it.

I wish I could but my car was sold on 21 April 2005 and 7 years is maximum....

So apparently the oil presure is at 2bar while idling and 4.5 bar when revved but the cams and cambearings on my motor have scuff marks on them and are blue(whatever that means). They are taking the sump off today to see what the crank bearings look like...

Does any of this make sense? How did the cams get damaged while the oil pressure is fine?

Sounds like a new engine will be on the cards
If they are blue they have been running dry and over heating

I hope so!!!! 2 year warranty on new engine

If the crank bearings looks good they are only going to order a new head, is it ok to replace parts on these engines, will it be the same again?

Hi,

From the sounds of it you have had
a Top end Oil pressure issue.

I do not think you will see 2.5 Bar oil
pressure at tickover with engine Oil at 85 degs.

If there are any issues with the Main Bearings
then its screaming replacement engine.

Even 2.5 bar, tickover cold, suggests that
bottom end will be ok, BUT,

Blue is oil starvation, over heating, but its accelerated wear I
would be more concerned with.
Reason being is that the wear particles will contaminate
the oil which can then cause premature wear throught the engine.

If the top end wear is excessive and over a short period
then I would be seeking a replacement Long Block engine along
with anything to do with the Engine Oiling.

Fine metal filing contamination in 10/60 sythn oil at
7000 rpm will increase friction wear dramtically.

The Gorilla.

Agree re the metal bits floating round.

On my E55 AMG I had an engine issue/noise. Normal people wouldnt notice, it was there from day one.
Any way it turned out to be the oil pump chain rubbing v v slightly on timing case, it had worn a groove slightly.

I stood my ground and got a full engine. I think the bill was £29,000

They wanted to just change the chain and casing. NOPE,

I am going there in the morning and I wont leave untill they agree to a new engine

Parts only if supplied on goodwill but NO WARRANTY on warranty replacements.

I will just be happy with a new engine which seem likely after they removed the Mainbearings. They also have marks on them and are apparently a bit blue.

I got some pics hope it sort of shows what they talking about...
