i'm pretty certain my oil cooling lines are weeping at both ends of connections. i would like to replace them but cannot find these parts to do so. does anyone have any suggestions where to look and estimated price? also while i was scraping grit and grease off with putty knife, i noticed that the "aluminium housing" that the oil filter screws onto and two oil lines leave, is hanging by two of three bolts. one of the holes has completly snapped off and the other has a crack in it. does anyone have the technical name for this "aluminium housing"? its a 98 LS 4.3l, 2dr vin"w" 5spd manual nv3500.
