The VIS Motors are only fitted to the V6 Petrol Engines not in the Diesel Variants of our Cars.
There are two of these motors in the Manifold one Power Motor and one Balance Motor. When either of these stop working or both, the Car uses more Fuel and it can significantly effect the overall Performance. They are made of Plastic and get contaminated with Oil which stops or Jams movement. I am a Diesel Man so I'm sure Stocktake and others will correct the above statement, or put any additional Information required. A Faulty Removed VIS Valve Motor Picture borrowed. Thanks.

Well done Dave......
Can I suggest a brief "how to ..." to go with it, so users can establish what should (or shouldn't) happen.

For the last 9 months or so I have noticed that I have lost about 65 miles in distance per tank-full of fuel around town - but seems to recover after a trip to cornwall (450 mile round trip) - then degrades over the next few weeks driving around town again. In other words, there is a noticeable difference in fuel economy driving around town before and directly after a long trip. Could this be related to a VIS motor problem? Are there any other symptoms with VIS motor failure? Harko PS> With regards to performance... wouldn't know, I never push the engine/car at all (keep to the speed limits and change up early) |

(even one that was 4 months old) Oil ingress unsecured components, and sticking vis butterflies all cause failure. When I got my V6 both mine were shot and you couldn't really tell that much or when they fail you just get used to it. You will certainly tell the diference when repaired. If you don't use high revs then the power vis isn't quite as important as the balance one which operates at lower revs and will have an effect on fuel your consumption. Don't worry too much your car won't come to any harm it just won't be at optimum. If you can get hold of the vis tester or alternatively get to one of the meets then we can test them for you and may be able to see about repairing them for you. Russ

Hi Dave Could you put us down on the waiting list for the VIS tester please ? Got a ZT which is not peforming and also making an odd whooshing noise, and an ageing (but beloved) 2.5 V6 which could do with checking. many thanks Gill Stephenson |
