osobne si myslím, že opak je pravdou...
až keď sa olej zahreje, je viac viskozny a teda v tejto časti može dovoliť jednoduchšie klepanie a teda vačšie hluky...
stači zadať skusenosti roznych uživateľov, je to klasický problém čo sa rieši bežne.
je toho hodne čo je potrebné preveriť, kým sa urči príčína...
pumpa sa rieši aj tu

http://promini.bmpdesign.coresense.com/ ... -Noise.pdfDIAGNOSIS PROCEDURE
Work through the following to eliminate other causes.
1. If a Fault is stored in the DME memory (e.g.,
misfiring,VANOS, etc.), then work through all the
relevant test plans first.
2. A one-time short shrill will be heard within the
first two seconds of engine operation. This is an inherent noise
caused by the first regulation cycle ofthe engine oil
pump. Tis is normal operation and no parts should be
replaced.
3. If the noise appears to be coming from the valve
cover or the vacuum pump area, refer to SIM11 02 08. To
verify the source of the noise, disconnect the vacuum
hose from the mechanical vacuum pump to eliminate
the knocking noise. This is not a failure of the
mechanical vacuum pump; do not replace any parts.
4. Ensure the noise is not created or eliminated by
depressing the clutch pedal, if equipped.
5. Disconnect the electrical connector from the tank
ventilation valve. If the noise disappears when the
connector is removed, reconnect to verify whether the
noise returns. If the noise returns, replace the tank
ventilation valve.
