View Full Version : VVT problems in the future Z24driver1986 10-22-2005, 01:50 AM I'm just curious, all of those VVT stuff looks really complicated and alot of electronics. Would you guys think that if something broke down it would be difficult and expensive to fix? unlike a non-VVT ecotec (less stuff there is to break down)? I personally would buy a normal 2.2 ECOTEC or invest some money into a longer warranty to fix it. 97cavie24ls 10-22-2005, 03:53 PM wuss there is 2 solonoids , and 2 hydralic cam movers big not alot of extra parts xonic 10-22-2005, 05:16 PM ...honda... wesmanw02 10-23-2005, 02:57 PM ...honda... Exactly. Honda's been using Variable Valve Timing for over 15 years (they call it VTEC) with hardly any issues to speak of. Its proven and reliable technology, and shouldn't be anything to worry about on the 2.4 SS. 97cavie24ls 10-23-2005, 03:55 PM actually vtech isnt the same as variable timing vtech comes on at a certian rpm , and changes the profile of the cam for more power vvt , actually changes the cam timing , but does nothing with changing the profile chevytech329 10-23-2005, 03:55 PM The trailblazer with the 4.2 uses VVT on the exhaust cam.
