Funingine La Esapament

[silviu75]

Se dau:

- aveo 1.2 cmc

- 3700 km

- mers turat

- euro 98 rompetrol

- pus de 3 ori aditiv curatire supape liqui moly

 

Problema este ca din intamplare am observat teava de esapament si am vazut ca este acoperita la capat de funingine atat pe interior cat si pe exterior putin.

 

Intrebare : este normal? voi asa aveti la ale voastre?

 

Chiar nimeni nu s-a mai intanlit cu acest fenomen?

 

O fi din cauza benzinei de 98?

sau a valve cleneru-lui

"Asa face toate". Este de la rulajul in urban.

[silviu75]

Tolin, sunt speriat mai ales din cauza ca am folosit exclusiv benzina de 98 si uite ce am gasit pe net:

 

01-027/02

GM Tehnical Bulletin

1995 - 2002 Millenia (KL engine) - MIL ILLUMINATION WITH DTC P0300 TO P0306

APPLICABLE MODEL(S)/VINs

All 1995 - 2002 Millenia models with 2.5L V6 (KL)

DESCRIPTION

After a cold start, MIL comes on with DTC P0300 to P0306 stored in the memory. In most cases, this concern may be caused by misfire occurring in one cylinder during idle. The use of premium fuel (high-octane fuel) may be allowing carbon deposits to accumulate on the exhaust valve seat, causing momentary insufficient compression.

To correct this concern, remove carbon deposits using a suitable top engine cleaner.

NOTE : After removing the carbon deposits, be sure to advise the customer to use lower-octane fuel (87 or 89 octane) to help prevent future recurrences. REPAIR PROCEDURE

1. Warm up the engine until it reaches the normal operating temperature, then turn the ignition off.

2. Locate the canister purge vacuum port into the intake manifold to feed the cleaner into the engine. This allows the cleaner to distribute evenly.

CAUTION: ^ Be sure to feed the "Top Engine Cleaner" into the engine through the correct vacuum port.

^ Do NOT use a PCV hose. If too much cleaner enters the engine, the engine may be damaged.

^ Do NOT use the vehicle vacuum hose. You have to prepare a new hose and fit an orifice (E5B6 13 986) into it to limit the suction rate.

^ With an orifice fitted into a new hose, about 7.5 fluid ounces will be fed into the engine, taking at least 1.5 minutes or longer. If the cleaner is fed at a faster rate than 7.5 fluid ounces per 1.5 minutes, excess liquid entering the cylinders may cause hydrolock, resulting in engine damage.

3. Fit the other end of hose into the container of "Top Engine Cleaner".

4. Choke off the hose with locking pliers (vise grips), then start the engine.

NOTE : Large amounts of exhaust smoke will be emitted in the next step. Be sure to connect the exhaust evacuation hose to the tailpipe and ensure there is adequate ventilation.

5. While cycling the engine speed between 1500 and 3000 rpm:

a. Remove the locking pliers from the hose with the orifice. The intake manifold vacuum will now draw the cleaner from the container.

b. Monitor the feed rate. Only 7.5 fluid ounces (half can) should be fed, taking at least 1.5 minutes or longer.

c. When almost 7.5 fluid ounces has been fed into the engine, reduce engine speed and allow the engine to stall. If the engine does not stall, turn the ignition off.

6. With the engine off, wait at least an hour (not more than 24 hours). This allows the cleaner to soak into the carbon deposits, increasing its effectiveness.

7. Repeat Step 1-5, using the remaining portion (approximately 7.5 fluid ounces) of the cleaner.

NOTE: Do not allow the engine to stall this time.

8. Remove the hose with the orifice and reconnect the canister purge vacuum hose to the intake manifold.

9. Test drive the vehicle 3 miles or longer to completely remove the remaining liquid and carbon deposits from the engine.

10. Perform engine oil and engine oil filter replacement service.

NOTE : With new engine oil and filter in the engine, start the engine, then raise the engine rpm several times to circulate the new oil throughout the engine.

11. Verify repair.

NOTE : Be sure to advise customer to use lower-octane fuel (87 or 89 octane). Periodic use of a well-known gas treatment (such as Chevron Techron) can be recommended to help prevent future recurrences.

Nu trebuie sa te speri, este vorba despre alt motor, alta tara si alt mod de raportare la pompa a cifrei octanice. Motorul tau este pregatit sa foloseasca si o benzina cu cifra octanica mai mare.

[silviu75]

Daca imi este permisa inca o intrebare:

 

Dat fiind cele de mai sus, Tolin, ce benzina imi recomanzi sa folosesc in continuare??

[tolin]

In oras, de CO95. Avantajele la CO98 se justifica doar cand rulezi de la 4000 rpm in sus, la drumuri lungi sau daca faci liniute.

[de esenta tare]

Stai linistit. Oricum in romania, benzina cu co 98 nu depaseste co 95.

Cun spune si tolin, in oras poti merge cu co 95, eventual schimba si jumperul pe co 91 (daca il gasesti).

[silviu75]

Nu am jumper de 91.

[zapacitu]

Ba ai.

Daca ce scrie in profil e corect, adica Aveo 1.2 hb.

E fix in spatele bateriei,in dreapta pompei de frana.

[silviu75]

Nu am zis ca e hb, este sedan, si am vazut ca e diferenta intre ele chiar plecand de la manualul de utilizare unde la

kalos recomanda min. co91 iar la aveo min. co95. Si crede-ma nu e jumperul, l-am cautat.

Edited March 12, 2007 by silviu75

[zapacitu]

Daca e Aveo si nu Kalos atunci probabil ca nu e.

Asta e.

Desi e ciudat, cam toate masinile de la Daewoo au jumperu asta.

[de esenta tare]

OFF TOPIC:

am gasit jumperul! Nu imi vine sa cred, ca dupa 3 ani l-am gasit in sfarsit!

Multumesc pentru indicatii, @ zapacitu!

Cauta-l si tu, @ silviu75. Sigur il vei gasi. Este lipit de aripa masinii, in dreapta pompei de frana, sub vasul de expansiune.

[MCojo]

Ca tot suntem fftopic: :

Poate gaseste cineva si mufa pentru goarna la modelele noastre!

[Abram Burel]

Aaa, e simplu: e sub consola mediana (intre schimbatorul de viteze si frana de mana). Un conector cu multi pini din care unul e pentru goarna

[MCojo]

Final de fftopic:

 

Mersi colega, dar nu asta e raspunsul pe care il asteptam...

Ma asteptam sa-mi spui si mie ca avem o mufa ascunsa pe undeva...
