I k of jb weld is not good for the head gaskets due to high oil pressure. But what about a coolant leak under the heads? It's dropping 1 drop per second. Pretty bad. 2nd engine rebuild due to the first one having an oil leak. Well the oil leak is fixed but now a coolant leak. Beyond frustrating.

Is this also a high pressure area? Can I use jb weld?

 

Man. Bummer. That was your rebuild that they messed up right? And when they fixed it, they said something about how the warrant is now void?

It's hard to tell where it is coming from. Did you wipe it down and then run it to narrow the origin?

From that location, it could just be your heater hose. But if it's coming from the block or heads, then depending on how much you drove it, I'd say you should still be able to some kind of work done by that mechanic. A rebuilt engine that leaks coolant in the first 5000 miles should be fixed on their dime.

 

It turned out to be the gasket where the thermostat is. They said it was leaking. They also replaced the top heater hose. Looks like i dodged a bullet.

It was dripping really bad, maybe 2-3 drops per second. Now its 99% fixed. Looks like there is still some leaking, but barely any. Still though, I feel like taking it back and having them re-do it since we at least know where its leaking from. Definitely ready to go back to work I think. The only problem would be if we get to a nice house and driveway, it looks like it might drip onto the customers driveway which wont be good.
