I have a D16Y8 in my 96 Civic EX Auto Trans, it has 167k miles on it, and I got it from some family members that I KNOW never drove it to the 5,300 RPMs needed to bust out the Vtec. I've only done it once myself, but I was wondering... At 167k miles, is it still safe to bust out the Vtec from time to time without having to worry about damage to the engine? The engine and transmission both work flawlessly. Excellent condition, just worried about the mileage. P.S. Yes, I'm a Honda newbie. This is my first car, and I'm trying to learn as much as I can about it.
