Factory cylinder head install
Factory cylinder head install
(OP)
I've been told by Cummins technical folks, including engineering, that an independent engine builder, such as myself, could never install the cylinder head as well as the factory. They said that no matter how skilled the builder, the installation will never be as good as factory. After many decades of mom & pop built engines, following time honored techniques, I find Cummins' conclusion hard to accept. What do you guys think. What is so special about a factory bolted down cylindr head?
Thanks
Thanks

Now if all said parts at the factory don't have a human touching them, then I would agree with the Cummins statement. Most that twist wrenches can be pretty haphazzard doing some of the important prep operations in doing certain jobs properly.

Also, I wonder if factory trained techs at Cummins' authorized repair centers learn the tricks, get the good parts, or whatever it is that independents lack.
Supposedly in the early days the cylinder heads of Corvette engines, unlike the passenger car engines, had their cooling passages filled with shaving cream so as they were being presented to the block on the assembly line no core sand could fall into delicate regions.
I know of a few instances when the (non Cummins) Central Office zone rep enlisted help from crafty dealership techs who on their own had figured out successful fixes for ugly factory installed/designed-in f*ck-ups . VW paid a friend handsomely to put on a powertrain rebuilding "school" using the techniques he had developed to chop 80% off the factory time for some oft required (!) warrantee overhaul procedure.

Do you think you'll get the chance to ask the Cummins engineer to of the indies' shortcomings?
