possibly ...

* cam slip?. Wrong wedge used?

* fails leak-down test?.

* boost or exhaust leak?

* turbo acting up or out of calibration?

* incorrect overhead valve adjustments?

* water or coolant in fuel?

* burning too much oil b'cause some rings did not get aligned correctly?.

* wrong injectors in wrong holes and no longer match injector trim codes?

* wrong inframe kit?

* Loosing compression due to bad head?
