Is it like rattling noise? Seems like you need a valve adjustment at the dealer.

Naw we have the hydraulic adjusters here in US, so valves never need to be adjusted.

Where is the noise coming from? It's probably the VANOS unit (very front of the engine) Look at http://www.drvanos.com , or http://www.beisansystems.com/ for an explantion.

You seem to know what you are talking about so i am going to assume you got a dr. vanos
If you did, what did you think of it

I installed a stage 2 Dr Vanos unit. It eliminated ANY Vanos noise. I also installed new primary and secondary timing chain tensioners. (not needed, but it's a while you are there thing)

If you have the time and mechanical skills, you can use the Beisan seals and anti rattle kit and rebuild your Vanos unit. Dr Vanos uses their stuff and you are really paying for not having to rebuild it yourself. The rebuild isn't hard, just meticulous and tedious.

How much was it for dr vanos if u don't mind me asking and is it possible to swap vanos with another e36? and if so does it have to be an ///m?

All in it was just over $600 in parts, and I got $100 back when I sent them my old Vanos. (Stage 2 kit, new primary and secondary tensioners, and a new valve cover gasket set) The Beisan stuff and the requried vise jaws will run about $100.

is install of the dr. vanos kit easy?

Look on the web site and read the directions, see if you are comfortable with it. It isn't hard, but then again, I'm a mechanical engineer, and have been wrenching on cars, and race cars for almost 30 years. You really do need a couple of special tools. (cam locks, flywheel lock, Vanos wrench, torque wrench...)

Ok so Stage I or Stage II I mean do you think it is worth the extra 150 for a couple gears and washers? And i forget where I read it but is it true that dr. vanos kit will make your car stronger/ faster than stock?

I don't think trying to do all this stuff by myself is the smartest thing since I am 16 and have almost no experience but at the same time i don't really have 600 bucks and my dad thinks my vanos is fine so thanks for all your help I really appreciate it

16? lol You're lucky to even have a car...

As for the "is it worth it"? Beats me... It was worth it to me.

No, it won't make the car faster. It will make the car run correctly, and quietly. While your Vanos may be working, it isn't fine. The seals are most def dead or dying. If you are hearing a rattle noise from the front of the engine, it's the Vanos.

Why does every1 say that

And yea my vanos is most def bad I can feel it and hear it
Am I killing my car drivin round with a bad vanos?

No you won't kill it, the worst thing that can happen is it just fails and you get a check engine light, and the engine doesn't work the way it's supposed too.

I'm 54, and got my first car when I was 19. It was a realy used MG Midget. I didn't get my first new car until I was 29, and the M3 I bought new when I was 39. If I had gotten a M3 at 16 I wouldn't have made it to 19... The car can write checks you just don't have the skill set to cash.

Anyway, good luck, try not to do stupid stuff.
