Well, after pulling the PVC valve out of the 1.6L Nissan (116k miles) that I bought about a month ago, I think its safe to say that my engine needs a good cleaning. The engine side of the valve was a solid cake of sludge, and the vacuum hose was full of crust. I have yet to remove the valve cover, but I'm pretty sure it doesn't look very good.
I can't find Auto RX at my local parts stores, but Seafoam is pretty easy to find. Will this do the trick? Should I just run it in from a vacuum line, or do I need to try something else?
