LONG BLOCKS INCLUDE THE CYLINDER HEAD**** And I am going to call around and look for some new pistons, havent found really anything on aftermarket pistons, seems running stock ones and getting them coated is what most are doing or running the industrial ones, but going to talk to a few compaines and see what is available, corilla, mahle etc.****ALL CPP ENGINES ARE CUSTOM BUILT TO YOUR NEEDS. The solution, fly-cutting the pistons, is standard work at any performance engine shop. Then Ill call the machine shop and see what they say. Going to the dealer today, to have the tech look at the head and inspect and see if he thinks I should junk it, or send it off to get checked out. This motor has been run up past 2000* multiple times, never for a long period of time though, but I am betting that is what cracked the head. The ISB 5.9L engine has a cast-iron block with 102.0 mm (4.02 in) cylinder bores and a 120.0 mm (4.72 in) piston stroke. But the crack was not near the blown gasket this time, like stated above the crack is between the exhaust valves on #6, and the gasket was blown between #2 and #3 cylinders, which the rings are what nicked my pistons. The Cummins ISB 5.9L is a 5.9 l (5,883 cc, 359 cu-in) six cylinders, four-stroke cycle water-cooled turbocharged internal combustion diesel engine, manufactured by American manufacturer Cummins from 1998 to 2007. When I pulled the head the first time I was in to big of a hurry and didnt check the head out good, so I am positive the crack was there at first, I didnt look at the head gasket extremely good, but I good not see anything wrong with it at all, so it was either inside the layers were the gasket was blown, or I was thinking it could have been from the crack in the head. ![]()
