On a trip to the beach this weekend, a little hole about the diameter of the tip of a golf tee (I know because I tried to plug it with one) developed in the heater hose tube on my F150. (For those who aren't familiar, the hose attaches to a tube that then winds about 8-10 inches down to the block on my 300 I6. The tube is tapered where the hose connects. The hole is barely accessible with one fingertip.) My engine compartment is now a nice shade of brown. Anyway, for a quick fix, I smeared some JB Weld on the hole. The next day, the hole blew through the JB Weld. So I smeared another layer on it. So far, two days and about 150 miles later, no problem. How long will it last? The winner gets the JB Weld residue mailed to him. /forums/images/icons/wink.gif

Its not wether the JB Weld will hold but how long before another rust hole appears. This will be like body cancer, it will rust around the patch....

I haven't had alot of luck with JB Weld - kinda like your first try when it only lasted a day.

I say 53.7 more miles.

Good luck.

I cousin scraped a hole in his oil pan (Non-Mustang) and he decided to use JB Weld to fix it so that he could get back on the road fast. That was almost a year ago and it still is holding up. I bet it will last a long time!

I'm going to say untill you really need the truck and your on your way to something really important. The possibility of destroying your engine aint worth it. I put a patch on my lightnings oil pan and fixed it that week end. I got fed up constantly checking it.

Epoxy typically looses strength with heat. If it is near the exhaust, look out.

I had to JB Weld the oil sensing extention into a previous motor because the block cracked. (Newly bored & prepped block, boy was I p.o.'d) It held fine.

You need to send this post to Paul Harvey. You could wind up a star of the radio! How come when Paul talks about things I know nothing about he is brillent. When he talks about things I'm knowledgible about he sounds like an idiot?
