what does the rest of the internet say?
its a farm truck, run it till it pukes
pour it in, what can you lose?
report back!
After watching tons of YouTube videos looks like the blue devil works pretty well ! Exactly like I said, if this doesn’t work Im parting it out and paying a shop to 5.3 swap it either way, just trying to get one last bit of mileage on this old 350

Years ago, for a cracked block we used to go to the pharmacy and get a quart of sodium silicate. That stuff will plug anything, LOL. Don't try this at home...
I am seeing people swear by this stuff so I’m just going to put some fresh gas get a battery and go for it, like I said nothing to lose if this doesn’t work I’ll part it out and just pay to have a 5.3 swap done right if I dump another dime in it

I used this once many years ago on a 350 and it worked fine, held - no issues. In fact I only used half the bottle instead of pouring in the recommended whole bottle.... FWIW

Just going to throw this in. Several years ago I bought a Ford Focus at auction real cheap because it had a bad head gasket. So I got a can of K-W block sealer. I followed the directions on the can and it worked great! Mind you this isn’t just a pour in and forget it product like Barr’s Leak. You have to do a flush and fill, then drain it and let it cure overnight. I ended up selling the car to a guy that was real happy with it.

hey guys, I have a great old farm truck, 93 2wd 350TBI, motor isn’t worth much at all, blown head gasket, has anyone tried blue devil sealer and does it work? I don’t have the tools to fix the head gasket and don’t want to put the money or labor into a head gasket repair as the engine isn’t even worth that. Thanks in advanced! Once again this is not my daily just a beat around truck, so I am not trying to dump 1000 in it ! Out f experience, does blue devil work? If so how many miles did you get after the initial repair
Do it! ya got nothing to loose. Tree fiddys are as common as dirt.
Just remember to plug off or isolate the friggen heater core before you do it!
What if you get another 10 thousand miles. And the heaters plugged.
That would suck.
Report back too!
We wanna know these things
remember, a small block chevy will run like **** longer than anything else will run at all.
