I have been fighting with my front main seals leaking for the last few months and have changed them out twice. My turbo pedestal is continuing to seep as well. I just rebuilt the HPOP with a kit from International. New harmonic balancer as we'll but I can't keep a main seal for more than two days before it starts to leak again. Are there any crank case pressure valves that could cause this problem? My check engine light will also pop on at around 2500 to 3000 rpm and I have tried scanning the code multiple times but none of the scanners I have used register it even tripped a code...........any opinions or helpful solutions will be appreciated!!!
