Vanos

What would be the best way about fixing my noisy vanos. Dr.vanos has replacement options for the whole vanos with their upgraded seals. Or I could do just besian seals. Have any of you guys just had a good indy do it for you?

I chose the beisan refresh and anti rattle kit and did it myself. Not very difficult. Although I think Dr. Vanos is a very good option, I have heard that their replacement vanos has the same seals as the original which would lead to the same issue down the road.

I had a noisy vanos, but it went away after using lucas heavy duty oil stabilizer. Over a year now, still no noises or issues. Just a thought.

How many miles, and what engine do you have?

'98 328i. Issue started at around 125k miles, I put up with it until about 135k when I added the Lucas. Now she's at 155k and still nice and quiet.

Ill try that, I would to do the vanos fix on my E36 because ill probably have to do it on my E46 sometime down the road.

Bimmer 765, let us know how the Lucas stabilizer worked for you. Maybe that stuff has the right things to restore the seals ? Would save a lot of work if so - probably would want to throw some in on higher mileage engines just a preventative if it works that well. I'm generally suspicious of these overhauls in a bottle but for seals a proper softening agent might just work. Anyone else tried this ?

Ill let you all know, since I have 183k miles.

We use Lucas quite a bit in the Rotary engines. I don't think it's so much about "restoring" or "swelling" the seals. I think it has more to do with its tendency to "crawl" up to areas that usually don't get very good lubrication.

Well when I get my replacement radiator back on ill drain a couple quarts of oil out and pour this in. I picked up the synthetic type of lucas so we'll see how it goes.

IF you are doing the vanos...

Dr Vanos.. not so much.

Nothing other than it uses the same seals as factory, which will just go bad eventually like the originals did.

Yea thanks.

Decided to change my vanos seals and no I have a problem. With mine being an automatic there is no room to get my hand up to the hole where the locking pin goes in. I have it at TDC and I'm ready to put the cam locks on. Would I be ok this way and make sure Im still at TDC before I put it back together.

The hole for the lock pin is in the FRONT, through the engine flange that connects to the transmission bellhousing. It's just below the starter.

I can see it from above, but with transmission color lines in the way its almost impossible to get to.

You really need the pin in place. I would never trust the engine to stay exactly at TDC while working on something as critical as the cams/VANOS. Figure out a way to snake that pin in there.

Well I was able to get it done without putting the locking pin in. Put it all back together and its way more quieter than it used to be. I still hear a little chain slop but that would be taken care of if I did the diaphragm spring. Still happy with the results.

Well its been about two months since I did besian kit and now the noise is starting to come back. I even put in a quart of the lucas oil treatment and it still makes a lot of noise. This happen to anyone?
