Just past 200,000 miles - Vanos Repair Next

JetPilot,

I just read the entire procedure and I think I'll be asking my mechanic to do this job. LOL. Anyways, one question for you: did you have to replace your crankshaft chain tensioner? Nowhere in the instructions does it talk about replacing it. It just lists it as parts to replace.

Never mind. I see removal and replacement of crankshaft chain tensioner.

I'm in Ontario, I haven't had any time to start to think about this repairs timeframe, although I think about it every time my car is idling and I'm in front of her and can hear the Vanos noise.
I would need to get the timing kit as well, that's one tool I don't own.

Ok so I have put about 800 miles on the car since Vanos repair and I still couldn't be happier. The car is quiet, like it should be, and I don't get the weird looks from folks at stoplights with their windows down wondering what the hell is wrong with the car that it sounds like freight train...

Car runs great, sounds great and performs like a V8 should!

Nice job, most Vanos problems are reported in I6 models, but apparently V8 also has this issue.
I don't think it is anyone's fault, any parts (whether it is brake pad or Vanos seals or aircraft parts) have their lifespans.

After 120K, most engine gaskets, seals, start to degrade slowly.

Great job, glad your car goes past 200K, these engines last a long time, if well taken care of.

did you have to remove the lower timing cover and chain to replace the vanos seals?

No. Google.

google....really. I'm not referring to the Solenod seals. According the pictures from Besian the chain has to be removed to take off the Cam sprocket and get to the old VANOS seals

Oh, so you found the beisan guide but can't read it, huh?
Seriously, man, read it through, look at pics. Do you see anywhere there they are removing the lower timing chain cover and the chain itself? No, because they didn't and because this is not necessary.
