RE: Cylinder Head Combustion Face Cracking Thanks for the bulliten posting. This problem has been around forever,.. but most of the heads I have seen myself actually crack like this were the result of a bad delete. The Big-name deletes, and all the smaller companies that copy their bad methods are notorious for this type of head cracking even at lower HP ratings. More on bad deletes... http://rawze.com/forums/showthread.php?t...01#pid5901 User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||

RE: Cylinder Head Combustion Face Cracking I've seen this type of crack countless times on engines in their standard factory form. There has to be some other explanation for it, perhaps the constant high coolant temps, perhaps the casting around the injector bore needs to be thicker, who knows.... | |||

RE: Cylinder Head Combustion Face Cracking They crack like that in this country whether they have a mm tune or completely stock . Some do it before they have done 400,000 km so not very many miles | |||

RE: Cylinder Head Combustion Face Cracking My theory on it is constant high torque combined with high water temps and high ambient temps takes its toll on these engines, the head is without a doubt the weakest link in these engines in my opinion | |||

RE: Cylinder Head Combustion Face Cracking This problem isn't just limited to isx. Most cats I pull down are like that on at least a couple cylinders. Thousands of heat cycles combined with high cylinder pressures and less than perfect injector flows, something has to give | |||
