VANOS

sp3ctre said:
What I suggested was that each member offering a service can add the (hopefully discounted) price to the discount section. They get one thread each and people can post their thank you's on that thread. Those threads also won't appear on the new topics list so we won't end up with a clutter of threads as we do now. It will also mean that people actively looking for a service will be able to see the feedback on the thread without irritating everyone else.

Yes, this does mean that there will be a small amount of commercialness allowed, but let's face it that was happening anyway, hopefully this will keep it in the right section and there will be a whole lot less bumping going on.

Thanks for the clarification, that all sounds perfectly reasonable. :thumbsup:

I think it means “come on” in Spanish.
 
Hi guys .
Seems I posted a Thank you in the wrong section sorry about that .
A s a member looking for work done on my car I do read the dealer feedback and to be honest there are very few without some sort of problem
And so a section like has been suggested sounds great .
:thumbsup: .

Well done Mack, you’ve put forward an intelligent and lucid argument yet had some pretty unfair stick for it, hats off for sticking at it :thumbsup:
I think the end result is the right one too :thumbsup:

Thanks I guess if it hadn't been me it would have been someone else, all the pms supporting my stance and acting confirm this. I knew alot weren't happy, I just didn't realise it was that many.

Hopefully the forum can now get back to what it's supposed to be
 
I think we need to have a separate part on the forum for where people can thank people for thanking people. Just sick of seeing all this thanks for thanking people. :poke:
 
I may have missed this somewhere in the thread, but how do you know if this needs doing or not? I've just bought a 2003 E85 with the 3.0 engine, which has now done 148,000 miles.... however, the previous owner was a mechanic, so theres every possibility its already been done if its a relatively straightforward job for a mechanic.

The car drives fine I think, but if theres an extra 30lbft of torque I could have in the midrange, that would definitely be worth doing!

Only thing I can add is that there is a noticeable change in sound at about 5000rpm, which I presume is something coming 'on cam' so to speak - should this kick happen lower down the rev range or something?

Dyno run is the only way really (hub dyno preferably) alongside another identical car. The change in engine note around 5k rpm is more the sound resonator than anything else.
 
and also how much lost torque are we talking about? if its 10-20lbft then I probably wouldn't worry as long as the top end power is still there, but if its 30+ then it might be worth considering. Anyone got and dyno plots from before and after they've had a Vanos unit repaired?
 
I think some of the diag software can also test VANOS operation. I would guess 20-30lb ft or so.

Yes it will need doing. The Vanos provides the torque all between 2000 and 5000 rpm. It can be tested.

I'm not sure for the 3.0 but for the S54 in DIS there is a VANOS test routine that will check for anything out of spec. Takes 5 minutes and makes sense to do that before doing work that might not be needed I would have thought.
