Default VANOS Pressure Hose Failure?

As an extension to another thread that discussed this issue briefly, I'd like to take a quick survey.
http://www.m3forum.net/m3forum/showt...=483987&page=3

OEM PN 11367837614

Mine is fine for now, but I met 3 people so far who has had these fail on track, which resulted in complete loss of oil pressure (I need a gauge/alarm for this) and pretty much trashing the engine.

But only a handful of cases out of hundreds of hard-tracked S54s out there doesn't seem alarming to me, so if the poll shows enough cases, maybe I'll convince myself to just replace it.

If preventative replacement is concluded, OEM or aftermarket?

Really need to add in a mileage marker in the survey honestly. I have not seen a single one fail. Of course I advocate updating to the newest revision when I have them in for vanos related service.

Ah, good point. Forgot that... but I can't seem to edit the poll now.

All - please chime in the mileage at which it failed if you remember.

I had one fail on track and it started a small fire on my exhaust. The same thing happened to another track friend. Mileage was about 45k at the time. BMW improved the part so if you have an 01-02 M3 it should be replaced. BW has one for $50. You also can't tell by just looking at the pipe if it's good or not. When it goes the 1500 psi that the vanos system runs at will make a real mess of the engine bay.

Just curious...is this a common reason why motors catch fire?

I know a lot of people remove the heat shields when they install headers...does this increase the likelihood of a fire?

Mine failed at TWS this year in May... fun to open your hood to a 4 foot geyser of oil, and entertaining for the track marshal.

2002 SMG @ 110k

Lots of mods, had the header heat shield was still in. My motor didn't catch fire, oil was coming out of the M3 side vents in the front fender, which is what black flagged me... so I tested the "douse engine bay in oil and run at track temps to see if catch fire" urban myth as false.

I have a 2004 and mine cracked at the junction between the tube and banjo fitting. The oil would mist out and accumulated on the underpanel where it would slosh out.

It was at around 20k miles IIRC (I've owned my car since new), and it happened at the track for me too. At the time I overfilled the oil by about 1/2 quart or more, but I have since then stopped doing that. I think I was told they are somewhat related.

Will....did i scare you at the track?? Lol

First one was at 103k miles on track at Lightning in NJ.
Second one was on the Garden State Parkway at 105k miles. Yeah 2000 miles later. Split in the same spot. I think it was making contact or was a bad piece.

Either way its 6L of oil out of motor in about 10 seconds.
