I’m trying to identify a specific vacuum hose junction and the associated lines on my 1994 Mercedes SL500 (R129).
Please see the attached photos. The area in question is the vacuum junction block located near the intake manifold on the passenger side (RH), just next to the valve cover. It looks like a multi-way vacuum T-connector or manifold, which in my case has been patched with some kind of sealant (I'm assuming preciously cracked or was leaking).
Does anyone know the part numbers so I can find them and replace? Despite having a PDF / parts catalog I can't seem to find them there for some reason.
After decades the PCV plumbing tend to become hard and brittle so it makes sense to renew them all. Set of rubber hoses should be around 100 €. The connectors are often reusable. For example Autodoc.se sells Febi aftermarket parts. The below list is for M119.972 that looks like the V8 in your photos. Only the pipe down to throttle valve is a bit elaborate to replace.
