BigDav782 Posted September 3, 2019 Author Share Posted September 3, 2019 Well, 6mm (1/4") or 7mm (under 5/16) sounds a lot better to me. But I'm cheap, and broke, so I'll make do with rubber. I'm just not that much of a fanatic. Thanks for the help all - found Amazon to be the best source, and just used fuel line hose in black. Changed out my PCV valve last night (with the grommet), and there was oil in one of the two lines that connected to it, plus oil in the spot where it mounts to the engine. Is that to be expected, or indicative of something else to worry about? Link to comment Share on other sites More sharing options...

So some oil around the PCV valve and in the hose is to be expected. Link to comment Share on other sites More sharing options...
