6 weeks ago I spent :$::$::$::$: because my head gasket let go, exhaust manifold was cracked, head was cracked so bad I took a core charge on it. New head with titanium springs, retainers, keepers, and o-ringed. ATS manifold, ARP head studs. I had the coolant system flushed and just got done putting $150 of Amsoil and fliters on it, for the second time, and I got home tonite and noticed a puddle under the truck getting bigger and bigger. I crawled under there and the bottom of the oil pan is covered in coolant. I looked toward the rear and the trans pan looks like it took a bath in it and so does the rest of the truck. I look a little closer toward the front, all the while hot coolant is consistantly dripping on my head like a Chinese water torture, to find the block cracked on the left side by the #5 cylinder and coolant is pouring out like Niagra Falls!!! WTF!!!!! I can't win for losing:CRY::CRY:. A new bare block from Cummins, that has been superceeded 8 times, is $2000:$::$:. My wife is ready to divorce me and I hate to say it but I'm ready to dump this thing and go buy a Silverado gaser. $4.20/gal really burns my :butt: and my mpg sucks. My 01 Yukon XL gets better mpg. Anyone have a spare NON 53 block laying around?????
