smarty turned on level 5 other than that its stock my problem it threw a hpcr code (high pressure commen rail) i cleared the code and removed the smarty back to stock drive about another 25 miles and it threw it again. i get home and remove the valve cover and the number 1 injector is spraying fuel and it has pushed all my oil out of the rear main seal so i change the injector and oil drive 100 yards and it throws it again i pull the valve cover again and number 4 is smoking white what do i do??????????????

 

Going to have to replace all the injectors. Also, going to need a new pop off valve.

 

Going to close, cause he also failed to disclose any performance parts.
