Re: How many miles you guys getting on your V6\'s
I changed my motor a 163,000, and it was still running great, and it was then transplanted into an astro van. A friend of mine has a 4.3 pushing 250,000, and has never had the valve covers off, yes it does have the normal start-up smoke from the valve seals, but the motor runs great. I just keep it tuned up and the oil changed. The motor in my blazer has 235,000 on it, and it still runs good, but I:m ready to build it up for some more HP! Hope this helps.
