hey guys, i finally took my gsl-se oil cooler off but i don't see a freaking crack. That thing almost killed me taking it off..and when i tried to hold the 21mm while i turned the adjustable wrench with the bigger nut off the fitting, it wouldn't budge. finally the whole thing loosened from the cooler hose and fitting. maybe the problem was the fitting or the crush washer. or maybe even the hose. would i be able to see the crack even through the black chipped paint on the cooler? let me know

Thanks
