Damnit excellent timing too! Since I litterally was going to replace the sob in less then 2 months. I took a look at it and it looks like the previous owner before me had this problem and used what it looks like jb weld on it. Lasted... fine for about.. 2 years that I had it.. I really really dont want to replace it with some cheap pos radiator or even a crappy overpriced oem one, I was just going to get a fluidyne for it in 2 months or so, problem is... Im strapped for cash at the moment and I cannot go ahead and do this. (I just ordered the egr valve itself, and I have an incoming 200 dollar registration which is already late to do with this car plus putting the 240sx together...)

Is there something better that I could use for the meanwhile other then jb weld to patch the damn hole up? It seems to be along the seam where the core and the top tank meets. By temporary I mean something that will last me at least 60 days?

I guess I could just take off the old jb weld and reapply again and keep close attention to the hood for steam and use the car for bare necessities only (work is about 2 miles, walmart where I do my grocery shopping is about a mile.)
