i just replaced the front crank shaft seal on my father in laws 97 pathfinder 3.3 liter after everything was done it ran for 30 minutes perfect went for test drive and seal now leaks constant stream was it not installed properly like not straight or to far in or out it has it spun out of place meaning either not right size or bad pcv causing too much crankcase pressure or would a groove in the crank cause this delay in leaking any help would be very much appreciated very much as there may be more than my pride of working on vehicles at stake here (i am in the doghouse tonight) thanks!!!!
