What is VTEC and How Does it Work? - EricTheCarGuy

VTEC or Valve Timing Electronic Control is a system that's been used by Honda in passenger cars since 1991. I believe the 1991 NSX was the first production vehicle to get this system. It has since been used in several other Honda vehicles. Late model VTEC equipped vehicles use the iVTEC system which also changes cam timing as well as lift and duration. The system is designed to give you the 'best of both worlds'. You get to switch between 2 cam profiles. One for fuel economy, one for performance. A lot of people think that when VTEC kicks in you get an extra Boost of power. Not true in my experience. It does however extend the torque curve to give you more performance after it does switch over. There is no set RPM where VTEC switches. The computer looks at several variables and calculates when to activate the VTEC solenoid. It's a cool system and for the most part rarely has issues. The most common issues I've seen with VTEC are the result of low, or incorrect oil viscosity. So if you have a VTEC engine, keep the oil topped off and make sure you use the viscosity listed on the oil cap. The animations are courtesy Honda Motor Company, thanks guys.

iVTEC How it Works -EricTheCarGuy
iVTEC How it Works is a long standing requested video. Back with I did the video on the VTEC explanation I was asked about doing a video on iVTEC which is slightly different than VTEC. First you need to understand the basic operation of the cam shaft, once you have that, and you know a little about how that cam shaft effects performance, you can then begin to understand how iVTEC works. In essence, as far as the Honda system is concerned, it varies the cam 'timing' to optimize performance and fuel economy. Many companies employ similar systems to this but they may perform the operation differently. This video focuses on the Honda iVTEC system. That said, you may notice that the VTEC system on this K series is a little different in that instead of having a cam with a higher lift and duration, it switches between 1 and 2 valves on the intake side. So when VTEC engages on this engine it actually activates another valve in the cylinder instead of changing lift and duration. It still alters cam timing via the iVTEC system however. Once again, to optimize power output and fuel economy. Either way, I hope this video helps with your understanding of camshafts, cam timing, lift, duration, VTEC, and iVTEC systems. Thanks for watching.

Re: Regular Oil vs Synthetic Oil -EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ I knew the original video would spark discussion and apparently it's caused quite a stir over at iATN. I also felt that some of what I said in the last video needed clarification. For those reasons I've made this Re: video. I'm not going to claim to be an expert on oil, I'm just speaking from personal experience. I still don't think I'm done with this topic and I invite any 'experts' who wish to express their opinions on this topic to join me in the next video(s).

How to Break In A New or Rebuilt Engine - EricTheCarGuy
Visit me at http://www.ericthecarguy.com/ I'm sure there is more than one way to do this but this is the way that I was taught and it seems to work as intended. The idea is to make sure the engine is fully lubricated before you start it up for the first time as we know all too well what happens to an engine without oil, in fact I forgot to show me filling up the oil filter with oil before I installed it sorry.
