I know this thread is 2 years old, but I've been needing to know this. I took a pair of calipers and measured the ID of the hose that goes from the valve cover to the intake manifold and it came out to 18.6mm. I found 19mm (3/4") hose online, but I'm not sure if this will work. My hose is leaking and I'd like to get a hose that doesn't have that weird insulated coating around it that I can get a proper hose clamp on instead of that piddly little metal clip.
Ideas? Opinions? This is the hose I was looking at: http://www.amazon.com/gp/product/B00...1&s=automotive As you can see this one is pretty expensive, so I don't want to buy it and it not fit.

Has noone replaced this hose with a non-factory part?

I can't seem to find the thread, but a while back someone asked the same thing and I posted the measurements. Rather than measuring the existing hose, measure the nipple that it will go onto at a point other than the flared area.

Yeah I had asked you at one point over on MI I believe, but I never could find that thread either.

Thanks Tolmach.
Would silicone be okay to replace that valve cover to intake hose with? I read that silicone isn't safe for oil. I'm not sure how much oil goes through that hose but I know there is some, because it's all over my supercharger throttle body tube thing.

It will fail early as oil will soak into it. And a lot of oil blows in to the intake that is why mine is blowing into the air, mmmm the sweet smell of oil.

My Weapon R intake tube came with a silicone hose and I've had it on for about 9 months with no issues. No softening, no swelling, no discoloration, no deterioration. Now that you mentioned it, I'll keep a close eye on it for any changes and will post them if anything happens.

Even though they don't look as nice (I really wanted some pretty blue hoses haha) I went ahead and just got a regular ol black piece of heater tube. It was $5 for 2 feet of it and a couple of steel hose clamps.
