Vaccuum tubes |
|
|
I have a 99' 528i and I believe I need to replace one or maybe all the
vacuum tubes in the engine (Mainly Drivers side) I am not sure where they
are at, I have worked on cars before Mainly Ford/Chevy. I've replaced the
Spark plugs on this car without a hitch. My questions are:
1)Is this something relatively easy to do on the I6?
2)Is there an online diagram that shows where these are located?

Thank you,

Why do you need to replace your "vacuum tubes"? Do you have a leak? If
not, I would concentrate on the basics like flushing your brake fluid
and coolant (using BMW or Saab "blue" stuff) every 2 years; and change
transmission and differential fluid (use synthetic like Redline or
Purple Royal) every 30,000 miles. Then just drive and have fun! |

Oh yeah, don't forget to change your oil AND filter. If you use
synthetic, every 5-7500 miles (depending on driving conditions); if
dino oil, every 3,000 miles!

Vacuum tubes? This is a car right? Not some vintage TV set...?
I think you mean vacuum hoses... What makes you think you need to
replace them? If you have a vacuum leak it is far more likely a loose
or cracked intake boot. There are not that many vacuum hoses in the
engine compartment of a BMW I6, so I'd imagine it would be pretty easy,
if you really need to.

There is a Vacuum leak on the drivers side of the engine. The car has 183K
miles on it, so I figure it might be about time to replace them all if one
has cracked.
Sorry I did mean Hoses. What are you referring too as the "Intake boot"?

Well the entire intake is on the drivers side of the engine if you drive
from the left side of the car.
Intake boot meaning the rubber intake pipe that connects the mass air
flow sensor with the throttle body. Here is a pic:
http://www.realoem.com/bmw/showparts.do?model=DM53&mospid=47585&btnr=13_0409&hg=13&fg=15
The boot is item #9, but any of the paraphernalia in that same general
vicinity would (could) cause the same problem.

Proper synthetic is good for 12-15k in typical use, trust the service
indicator and don't use anything else.
My last sump full of Castrol SLX was replaced after just under 13.5k
miles, when the yellow light on the service indicator had been on for
three days, of mostly fast road use and was maybe half a shade darker
than the new oil. A home pour test suggested that its viscosity was
also uncompromised.
Buy quality lubricants you can trust, then trust 'em.

Yup. 3000 mile oil changes are from the '50s with '50s oil and '50s
materials/ standards of machining. Things have moved on.

Btw, I tried synthetic oil once in my car and it burned, fast. At about
1000 miles, I was down almost 2 qts! I added oil and still it burned.
At about 2500 miles I changed it back to dino oil and its runs like
new.... |

Not on my car. The indicators are still in the green when my oil is
black and dirty. |

The oil is just doing its job. It may not be at its capacity for carrying
debris.

Actually, the current service indicator is run strictly by fuel usage.
After so many liters, a light goes out. X's 5 and its the yellow light
indicating the oil change. Fuel burn (greater in urban than highway) is a
good approximator of the oil's condition, but not absolute. There's no oil
analysis going on under the hood.

On the flip side, the oil in my V8 540i sill look basicly new, just a
shade darker after ~6k miles

No, there's no analysis, but the calculation is more complicated than
just fuel burned.
