My friends dad has a 2004 Nissan Titan (RWD) This thing has about 50,000 on the clock and its got a NASTY leak from the lower oil pan. (The small one.. It looks like a big tumor on the oil pan.) I have been trying to locate the gasket for this part, but Ive been told by local part stores that it is just silicone. Please somebody help me with this. Im not willing to rip the truck apart without finding out first.
