Eventuale motive de consum ulei? Dintr-o data!, 1 litru de ulei la mia de KM Options

[Alexxx]

Masina consuma intre schimburi cam ~1 L la 10.000 KM. Problema a inceput acum 2 luni cand s-a aprins becul de ulei. Am scos joja si era uscata, motiv pentru care am completat un L, considerand ca este o anomalie... sau cine stie ce. Intre timp am mai facut o mie de KM si cand am verificat e din nou pe minim. Asadar in ultimii ~2.000 KM am pus 2 L de ulei si sunt pe minim! (((
Masina trage PERFECT (ca in prima zi), nu scoate nici un fel de fum, nu are pete sub ea si pot spune ca merge impecabil! SI TOTUSI ULEIUL DISPARE MISTERIOS.

M-am progr la Filaret sambata!

A mai patit cineva asa ceva??

PS: Am observat ca il mananca MULT mai repede daca fac drumuri lungi (in regim de autostrada)

Consumă 1 litru la mie sau 1 litru la 10 000 km?

Dacă ia un litru la 10 000 km, consumul de ulei este normal, mai ales dacă ai un stil de conducere sportiv.

1 litru la mie este un consum un pic mai mare, verifică dacă nu există pierderi de ulei.

Poate s-a stricat piesa 1: http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=15

Are o membrană din cauciuc care se poate sparge.

Exact piesa de care povesteam

1L/1000

Typically if you have high oil consumption on that particular car its usually because of a crankcase vent valve being stopped up. Its not a terribly expensive part, but it is labor intensive. Its located under the intake manifold and connects to the intake manifold, valve cover and the oil pan. It basically separates oil from the vapor in the upper engine and returns the oil to the oil pan. If it gets stopped up, then oil vapors will get drawn into your intake and your motor will burn it (slowly but consistently)

They are very common to go bad every 60 to 80K miles. Also, if you have it replaced, there are several hoses that should be replaced with it (4 total I believe) I'd recommend having an experienced BMW tech perform the repair.

Do you notice if the car idles rough at all? That is usually a sign of a vent valve failure also, since a vacuum leak is usually created by a bad valve. Eventually a check engine light results with lean mixture faults. Also, some oil usually leaks out of the bottom of the valve where the drain hose has deteriorated.

Oare vb despre acelasi lucru?




PE ALT FORUM, acelasi raspuns dat de alt mecanic!

Question - My 2002 325i seems to burn about 2-3 quarts of oil between oil changes. I change my oil between 5-6k miles and I am worried about how much oil it is consuming. What could this be?

Answer - Your car does burn a small amount of oil between oil changes. But the amount your car is using up is excessive. It sounds like you have a clogged crankcase ventilation valve or hose. This is a common failure point on the M52 and M54 motors. Most of the time the reason these do get clogged up is due to the oil change intervals BMW recommend which can give the valve a quicker build up then normal. The way to fix this issue is to change the valve and the hoses too. The hoses ten to get dry and crack so it's good to do all of them at the same time.

When doing this repair here are some items to change while your there.

Intake Manifold Gaskets
Fuel Injector seals (top and bottom)
Oil Separator Valve
Oil dipstick o-ring
All the hoses connected to the Valve

BMW TECH TIPS!
