I’m looking over the vac hoses on my 97LX. I’ve got a thicker vac hose (off the front of the VCV) under the upper plenum that I plan to replace. Aside from that the other hoses look fresh and OK. However, while some of the smaller hoses are the OEM (all the small ones under upper plenum appear OEM and good) with Japanese characters, some of the smaller ones are non-descript. The hoses going into and out of the EGR look new but they are non-descript. I can pull them off the barbs with little / no resistance. There are two side-by-side vac hoses on top of the plenum next to valve cover. I’ve seen others’ pics and it looks like one of those short hoses (or both) should be clamped to the hard lines. Lack of clamps and non-OEM vac hoses a possible source of vacuum leaks? Stay tuned. I’m trying to find my vacuum gauge I’ve never used to find out.
