kazkaip nepamenu kad buciau sakes taip

Motortech, tikrai neabejoju, kad gerai ismanai vanos klausima, zemiau imetu didele citata is gana autoritetingo saltinio del vanoso problemu, kokia tavo nuomone apie tai, teisybe raso, ar ne? Manau, sita citata suteiks papildomai ziniu ir kitiems, kas domisi vanos klausimu 8 cilindru varikliuose.

Let me point out that 1998 was the first production year for european E39 M5s. Most quirks were fixed in 2000 when the E39 M5 was launched in the US.

What does Vanos do? ****************************

The Vanos units change the timing reationship between crankshaft and the four separate camshafts. This directly controls valve timing both on intake and exhaust. This is what gives the wonderful flat torque curve. This is what gives the wonderful full-load-high-RPM engine note. This is what makes an S62 engine an S62.

Two kinds of Vanos noise in the E39 M5 ****************

There are two kinds of Vanos noise.

The first kind is loud rattle only heard at startup and stops within a minute. This is fixed by installing the Vanos oil pressure accumulator.

The second kind is loud rattle (like an old Mercedes diesel) that gets worse the warmer the engine is. This calls for replacing parts of the Vanos units.

History of extended warranty *****************

There has been several fixes on the Vanos system. In the US, BMW initially denied any problems, but later after pressure from owners (many of whom are members of this board) issued free Vanos oil pressure accumulator coverage until December 2003 / 3 years / 100000 km .

History of fixes **********************

First of all, on cars built up to November 2000, get the Vanos oil pressure accumulator installed. This is a compressed gas oil pressure vessel and a shutoff valve that takes high pressure oil (200 Bar) from both Vanos hydraulic pumps while the engine is running and stores it until the nest enigine start. There is an electromagnetic shutoff valve that keeps the pressurized oil in the vessel when the engine is stopped.

(very neat design, much better than the electrical priming pump they used before)

The installation procedure (takes about 1 day for 1 mechanic) is described in Service Bulletin 11 01 01 (661) issued March 2001.
This warranty action expires December 2003 / 3 years / 100000 km, whichever happens first, so hurry up.

This should take care of all Vanos noises that disappear by themselves a few seconds after starting the engine.

Most Vanos units will still make a bit of noise. If the diesel-sounding Vanos noise (after warm-up) is more than you are willing to accept, or if it keeps getting worse the more miles you put on the meter, you need to get some parts inside the Vanos units replaced. To get this under warranty, you need to be kind to your SA.

(btw there is no such thing as a completely noiseless Vanos, but in the case of my car subjectively 75% of the noise disappeared)

The production-dates and engine-numbers below are from BMW Germany recomending replacment of certain Vanos parts on S62 engines in case of loud rattles.

On M5 built before mid-July 2000 (engine number 60232305): replace
spline-shaft (BMW part number 11 36 4 781 417, 4 needed per engine) and
spring discs with support washers (BMW part number 11 36 7 833 218, 4 needed per engine).

Built after that, but before mid-September 2001 (engine number 60572609): replace just the spring discs with support washers (BMW part number 11 36 7 833 218, 4 needed per engine).

Built after that: everything ok from the factory.

I´ve had both spline-shafts and spring discs replaced, (and the cogwheels the spline-shafts drive, as well as the spline inserts in the camshafts for good measure), and it reduced the noise a lot, but not completely.

It is 1.5 - 2 days work for two mechanics, one of which needs to have M training.

Also note, if you get this done the Vanos will sound awful for a few days or so, until all air that gets trapped inside is pushed out by the oil flow.
Then the sound gets very much better.

Vanos niose in the E60 M5 ***********************

The good news on Vanos noise aestetics is that the E60 M5 has horrible Vanos noise at idle, far worse than a non-upgraded E39 M5. I think this will bring Vanos noise into fashion as the "Sound of the M engine".

cia netiesa nes net BMW manual raso kad garsas turi praeiti po poros minuciu kai buvo padarytas remontas, jei trunka ilgiau tai reiskia kazka netaip padariai
pora detaliu kur jis raso kad reikia keisti nepadeda kartais ir pora detaliu kur is tikro reikia keisti BMW neparduoda ir padarytos jos is labai idomios medziagos. Del akumuliatoriu alyvos jau senai ta problema aiski ir pats pora esu retrofit dares, S50 juos turi nuo 1992 metu kiek atsimenu, reikia zinot kokia kryptim juos statyt ir t.t.

dar norejau pridurti , jeigu jiem pataisius vanos nepraejo garsas dar 2 dienas tai galiu pasakyt ka jie blogai padare greiciausiai pastate alyvos akumuliatorius aukstyn kojom ir oras negalejo iseiti is ten.

Bet kas keisciausia is principo anas zmogus raso (ir nemazai kitu taip pat), kad v8 varikliuose ypac m5 (net ir V10 naujame) tas garsas vis tiek esti daugiau ar maziau, o remontas nera butinas. Kaip kitur skaiciau, vanosas ypac reikalauja remonto 6cil varikliuose del ziedu is gana prastos medziagos, kuriuos reikia keisti (m3 variklyje pvz), o 8 cil lygtais problemos gludi kitur...

paprastos medziagos stovi M50,M52,M54 motoruose S54 jau kitaip, 8 cyl viskas teisingai ! garsas yra del teplao akumuliatoriu, saibos nevisada padeda, dar jei ipilsi netoki tepala koki reikia bus dar blogiau del tepalo spaudimo, dar problema yra del spaudimo reguliatoriu kurie stovi S motoruose su kuriais irgi reikia zinoti ka daryti

Ok, truputi nuraminai mane, nes jau galvojau man visus ziedus keistis reikes. Zodziu, po keliu savaiciu apsilankysiu ir gal tada paderinsim ko ten truksta (pvz ta tepalo akuma ar pan), nes tas lengvas dyzelio garsas mane kartais labai nervina.

Tai soliusinas barskejimo ties 2k apsuku yra koks? Ten pats vanosas barska ar kazkas kito? fanuose skaiciau kad solenoida pakeitus (taip turbut tas daiktas vadinasi kur atidaro sklende tepalui) susitvarkytu. Ar reikia pirkt visa komplekta uz 1.5k
jei nereikia tai kokia sutvarkymo kaina?

solenoidas tik pastumia pistona, kad tepalas patektu i cilindra ir butu pasukamas velenelis. matuojant pasukima su kompresorium, sake, kad mate, jog oras su tepalu eina pro sona ir velenelis tik dalinai pasukamas.
solenoido beda butu tik tame, jei jis neveiktu.
ir butina, kad tepalas butu geras ir laiku keiciamas, nes ten tepalas per milimetrine skylute paduodamas. gali del apnasu ir pats pistonas (kuri pastumia solenoidas) apsinesti ir strigti viduj.
na neaisku kokio minkstumo gumele buna gamykloj dedama, bet dabar kai dejau naujas, tai senoji buvo sukietejus ir susispaudus, tai nera ko stebetis, kad nelaiko slegio. ta ir nori pabrezti siu gumeliu pardavejai.
o del garso, tai dar ir gali buti kazkiek del nusidevejimo tos vietos (daliu pavadinimu nzn) kur vanos dantraciai jungiasu su velenelio zvaigzdute. bet del tu turetu garsas jei ir buti, tai tikrai nedidelis.

as tikrai esu isitikines, kad naujo vanos dejimas, neduos daugiau naudos, nei tik gumeliu pakeitimas. nebent yra mechaniskai pats vanos pazeistas.
cia apie M50, M52 ir kaip minejo M54.

neimanoma apsisprest...is dalies jo net neverta keist uz tokia kaina,vaziuoji kol vapse ten issitasko Blogiausiu atveju viskas,ir kadangi jau 1,5 reiks turet kisenei,tai JEI(PABREZIU-JEI) jau IR LABAI ten issitaskys baisiai,dasimetiai tuos 300 uz galva kita ir viska sutvarkiai pakeitei IR toliau puskuoji sau ramia galva.kitos iseities nera cia....norit peikit norit ne,bet cia tik toks variantas belieka...nes 1,5k ir TAI ju dar neuzteks,kist i 93' metu auto,tai tikrai neapsimoka zmones...gera tepala mauki i vidu ir keiti laiku-to uzteks pilnai manau. tokia man nuomone visus postus paskaicius persasi
Ps: nekalbu apie naujesnius BMW

niekas ten neisitaskys ir galvos keis nereiks

as kalbu apie blogiausia atveji....taprasme kol jam tas atsitiks nuvaziuosi N kilometru ir nk keist nereikes,nereikia sukt galvos del nieku,kai jau subirs tai tada ir tvarkyt,gal kvailai skamba,bet kitos iseities nera.

vazinek ramiai nieks ten nesubyres

tikekimes

nesinervuokit viskas bus gerai
