Coolant leak found not good!!

So yesterday it looked like the motor mount hole was leaking. After an hour of looking with the system at 18 psi it turns out the head is leaking. No drain bolts studs or gaskets. Right between exhaust hole 2 and 3. Corroded right away. Almost looks like a small caterpillar size errosion. About 1/16 by 3/8 spot and antifreeze slowly comes out. If i clean the head good will extreme heat jb weld work???? Cant afford 2000 for new heads

Re: Coolant leak found not good!!

So between cylinders 4 and 6 of the drivers side exhaust manifold leaking through the head?
Can you show us the hole and its location?

JB weld is some good stuff, when it comes to the high heat I think there is a product by quicksteel that is better.
I am curious to see what these guys who have been around the 7.3 for years and know about this stuff will say here....

Re: Coolant leak found not good!!

Junk yard head is $100. Plus a head gasket and bolts. $100. Then have the valve seals replaced and it checked $100-200
Total $400

I don't think jb weld or the like will hold. I think it's half assing it. I had a hard time using it on my irrigation pump. But that's just my opinion.

Your motor is out of the truck right?

Re: Coolant leak found not good!!

It held 16 psi for over an hour. The drip was so small. So why not for 10 bucks for jb weld and two hours of my time. Farthest i go with this truck is about a 10/20 mile radius so why not try it im curiuos

Re: Coolant leak found not good!!

I hate salt. And I've never had to deal with it.

It's worth a shot. Worst that can happen is you have to replace the head if it doesn't work and your not out much.

Drain the coolant, wire wheel It, grind on it a little. Pull a vacuum on the system. Spray it with carb cleaner. You may even want to hit it with a little heat to try and burn it off. Then apply some jb weld while there is a vacuum. Try to suck it in and keep the antifreeze from contaminating it.
