Ahoj, dnes mi začalo také cvakat. Cvaká to za studena (za tepla ještě nevím) a při přidání plynu se cvákání zrychluje.

Můj tip zdvihátko někde na 5./6. válci. Kolik stojí výměna? Díky chalani :)

Cavte precitajte si ku tomu nizsie co je v Bentley manualy:
An occasional ticking or rattling noise from the hydraulic valve
adjusters (HVA) elements may occur during cold engine starts or
frequent short-distance driving. This condition can not cause any
damage to the engine, and usually remedies itself with a longer
driving distance or operating times at full operating temperature.
In this situation, the lifters can bleed down or have trapped air
causing ticking/rattling noise and may require bleeding, as described
below. The bleed time may take anywhere from two minutes to a
maximum of 30 minutes.
Procedure preconditions:
• Engine running at operating temperature
• Vehicle stationary on a level surface in a properly ventilated area
• Engine oil level correct - not underfilled or overfilled
1. Bring engine up to an operating speed (no load) of 2000 - 3000
rpm and maintain this speed for three minutes.
2. Let engine idle for 15 - 30 seconds. Listen for whether the noise is
still present:
- If engine is quiet, procedure is finished.
- If engine noise still present, repeat procedure; perform steps 1 and
2 up to a maximum of 5 times.
If the noise remains after performing the bleeding procedure 5 times:
proceed by performing the procedure for a final time, also at an
engine operating speed of 2000 - 3000 rpm, but for a total time
duration of 15 minutes. If noise returns after multiple bleedings, the
cylinder head may be faulty and require replacement.

Diky.

Projel jsem to a prestalo to. Predtim jsem jel kratkou trasu a 3x nastartoval a nechal chvili klepat na volnobeh. Dle mistra na BMW je toto normalni chovani zdvihatek :)

normalne chovanie nie, ale caste :) s tym ze vymenou vsetkych zdvyhatiek sa problem casto nevyriesi, kedze problem je v ich mazani nie v nich samotnych. mne velmi zriedkavo ale stava sa (pri castom popojizdeni v meste) ze sa ozvu aj na n53ojke
