My husband has a 99' Dodge Ram 3500 with the Banks turbo package. Apparently we are the owners of the dreaded 53 block and he has a 6" crack on the motor and the truck overheats excessively. We tried K&W block sealer which worked like a charm for about three months and now it is starting to overheat again. My husband thought it would be a splendid idea to clean the crack very well and JB weld the crack. Has anyone ever done this or know of someone that did successfully?

JB Weld will do a good job, but you'll have to scratch the surface of the oil pan real well. Then get a peice of metal that will cover the crack completely and have extra all around the edges of the crack. Sratch the metal patch real well on the side that goes against the oil pan. Make real sure the oil pan is totally clean of ANY oil what soever. Put the JB Weld on the patch so it covers the entire patch use enough so the JB will squish out around the edges and place the patch over the crack. You will have to hold the patch against the oil pan tightly until it sets, wedge it if you can. Allow the JB Weld to cure for 24 hrs and refill the oil. This should make a permanent repair if done right. I fixed an aluminum oil pan on a Honda Magna motorcycle like this and it never failed. I rode it for years afterwards. Remember wedge the patch and let it set for 24 hrs. Good luck!

It's a temporary fix at best. If it's worth your time and energy, then it's worth the 6 bucks for JB Weld. Start looking into replacement engine options. Check around for the best core value considering your block is junk. Perhaps the JB Weld will keep the block sealed long enough to get things sorted. Good Luck.

Why not take it to a proffessional welder who knows how to weld cast iron.I have welded a block in a big rig it requires using a rosebud torch to heat the cast then welding it with a stick welder with the correct rod.It might make for a permanent repair or atleast add considerable longevity to the motor.

Yes, I have. Used it on a 305 a week before it went from LA to L. A. Also JB'd a bottom pulley to a crank on a 2.2 Mazda that wallowed out a key. Ran for 43K.
Give it a try.

It probably won't work because the engine's operating temperature and the stresses to which the engine is subject are both too great for a fix. The only thing that will work is replacing the engine. Sorry! Good luck!
