Vanos bad or setup wrong - need help.

Hi All,
New to this forum, but not BMWs (my current garage has a 2008 135i and a 187 325ic with M50 swap and I have owned about 10 over the years.

Anyway, I have a 99 323i with a M52TU (dual Vanos), bought with a blown headgasket (overheat?), I had the head rebuilt and sourced a new shortblock since the headbolts kept pulling threads.
I took pictures during dis-assembly and when I reassembled the VANOS, I set the gears and all on the wear marks and per the pictures I used on teardown. Cams were set perfect, but when I rotated the crank through the cams moved on the VANOS stuff and I assumed once the engine ran and oil got up there it would sort itself out.
So, the engine runs, seems to idle just fine, air pump runs for a couple of minutes and then quites. in neutral engine seems to rev okay, but in gear it responds very very very slowly until about 4k rpm , then takes of like a banshee.
I am confident it has something to do with the cams advanced too much or not enough. However, I have no experience with VANOS so I do not know how to troubleshoot, or do I know if I even set it up correctly - although must be close as engine does run.
ohhhh - when running gives me a code of CAM posit sensor bank 1 bad, so I ordered and replaced Intake cam sensor - no change in performance though.

Well, sorry for being long winded but I thought more info would help you to help me.
Thanks
Rick

If you don't have the Vanos tools to set the cam timing, you'll never get it right and the car will never run correct.

so I had some discussion with Rajaie after I discovered his site and bought a VANOS seal kit.

I also bought the tool set from eBay, it just came Wed (30 Dec) but I wasn't able to get to the car until today.

Anyway - I am a believer! You cannot set the VANOS up correctly without the Jigs (tools). That is a fact.

My intake cam was 2 teeth retarded. Never would have figured it out with the tool.

I will rebuild the VANOS in the and get the rest back together in the AM.

Sooooo.....Thanks ALL.

So how much are these tools? I don't see a price on their site.

No - the "tools" are only needed if you mess with the chains/gears......
