Bad Head Gaskets? Or Bad DIAGNOSIS? 4.3 V6 S10 Blazer Fixing!

We hate to say it, but a whole lot of times, a misdiagnosed issue sometimes will sideline a repairable vehicle. That's pretty much exactly what we have here with this 2004 Chevy S10 Blazer and the 4.3 V6 under the hood. Previously told that the head gaskets were bad and would need to be replaced we discovered the TRUE failure!
A big part of what we do outside the muscle cars, race cars, and custom stuff, is simple automotive repair. Just old fashioned mechanic-ing and that's what we have here, hope you enjoy!
