![]() There is absolutely no smoke coming out from the car. The best way is to get a machenic to check the car out.Ģ. 1 liter per 250KM is a lot of oil, i don't think oil leaks could cause this amount of oil to lose. Get a machenic to lift the car up, remove the undertray and inspect for oil leaks. Therefore no oil on the floor doesn't mean it's not dripping oil. What I would do is, stand behind the car, start the car and let the enigne to idle for 5 minutes, then get someone to quickly rav the hard for a coule of times (4000-5000 RPM), if the engine burns oil, you will definetly see the smoke.Īnother thing is, the B6 has a undertray, which can collect oil drip. We normally use fully synthetic oil in those engines, so the car will blow light grey smoke if the engine burns oil, which is a bit hard to notice. The danger thing is, if the sensor is faulty or not as sensertive as before(like the first B6 2.0 I had 3 years ago), the driver won't notice when the engine oil level is getting too low, and the whole engine can get ruined very quickly. The two ALT engined B6 that I had before both uses a bit of oil, which is normal being a european car. My mum's B6 2.0 needs 0.5L topping up every 2500km. 0 pressure on idle and full boost.I assume if you know how to top up, you should know how to check the dipstick. So i put my vacuum/boost gauge pipe to the dipstick, and saw almost no needle reaction at all. I read about dipstick pressure measuring, to check if the PCV valve works good on idle and in boost. I know that remaps can cause engine to burn more oil, but NOT THAT MUCH) Could the clogged oil pan channel or clogged PTC nipple cause that oil leak/consumption? But i replaced it.Ģ things i didn't clean and learned about it after the job: there's PTC valve near the turbo and oil channel in the oil pan, that's often totally clogged.īUT. Mechanic said that the turbo is sucking the oil from breather box somehow. All i can see from exhaust is thin white smoke, like water from condensation, but it's smoking all the time, after warm up. If the turbo was dying, the oil will be much darker, and exhaust will have dark deposits/ black smoke. They said that there's some oil outside the turbo cold side, but it didn't die. So i went to the mechanic today, raised the car and they checked if the turbo was leaking. I was 99% sure that turbo died 6 months after Melett warranty. I was thinking that turbo core I replaced 1,5 year ago has just broke - that's why there's oil in turbo pipes. Lots of leaks and absolutely no change in oil consumption after repairs. I filled oil to 1/2 dipstick, drove 200 kilometers, and then I had 1/4 of dipstick scale. I cleaned that little hose that goes from banjo bolt, cleaned lower and upper drain holes in the engine block. It was clogged with oil mixed with water, from condensation. No pressure buildup, glove was sucked in. So I learned about PCV system and did a rubber glove test. No leak, but - oil consumption STILL the same or even worse.įor now it's about 0.6-1l for every 1000km and I found there's still some oil in turbo pipes. Then the main crankshaft seal was leaking (that from timing belt side) so i replaced it. Replaced that gasket, no leak - oil consumption the same. So i found the turbo return gasket was leaking, because i messed it during turbo replace. Then I found the oil inside turbo pipes, so I got CHRA core from Melett and replaced. ![]() ![]() ![]() Since i bought this car i had problems with oil consumption, leaks.įirst the VVT pulley was worn out and leaking, so replaced it.
