I bought this car a month ago about, I have replaced several things, bought code reader to help with that.. I figured out the oxy sen were bad, the map sen was bad, replaced gaskets, thought that I fixed timing but it started sounding like shit so I tore down again to check and it seems like the crank advanced again, but vanos still in same spot. Seen something on banjo fitting in vanos that said to apply air to find or reset vanos? Did that, now sounds like air is blowing out of exaust side of vanos? Can u help?
Unfortunately there is a specific set of tools required to time your engine. HERE is a link to the type of tool, you may find it cheaper if you shop around though. If you don't have that set I would invest, it will save you a lot in the long run! Also, invest in a Bentley service manual if you haven't already!
As for applying air through the banjo fitting, you do that when you're timing and installing the VANOS and air blowing out the other side is normal.
Let me know where you are in the process right now and what else you need help with and I'll help you get it back together! Please leave me a positive rating when you get a chance as well, we can still continue this conversation after you've rated me.
Thanks and good luck!
PS: I have the same car and love it!
With a code reader , looking at the timing , what values should it read? like when its running what should the reading be? when u rev it up? Then my car makes a clunk clunk sound at a idil stage, is that normal? Bank one and two are lean, engine has no vaccum leaks? Could it be the MAF sensor? That is the only thing that hasn't been replaced( waiting on the mail man).
The only codes it is saying right now is Bank 1 and 2 lean , misfire on1- 5 then shuts down 5? It doesn't sound like it shuts it down, it still sounds the same. If u unplug the MAF it seems to run better, but code reader says circuit low? Shouldn't it say open or low?
No haven't got tool yet, just been trying to do with out it. Been watchin a lot of U tube. Sorry I am bugging u.
