Yep. You experienced a very common issue that plagues the 1998+ 3.2/3.5. It's my understanding that isuzu "revised" the gasket to prevent this from happening, but I've seen it happen to 2001's so I guess it's not too revised. An all aluminum engine expands and contracts a whole lot. That in combination of this intake design causes this. Isuzu will replace them for free for 10yrs/120Kmi for 2001-2003, and really should replace all others for free as well.
