a hose broke while changing the valve cover gasket

So I just finished changing my valve cover gasket. And when I was closing everything up one of the hoses was very brittle and it snapped in half. I have posted pictures. Can you tell me how important that hose is and what its function is? Can I drive the car fit a while until I fix it?

It's part of your air pump system. It will probably cause a vacuum leak and throw some codes. Not sure how it will affect your drivability. Plug both open ends. You can get some vacuum tubing at your local parts store and fix it in a few minutes.

It will cause rough idle on start up.

Mine broke too, and I just walked a couple of blocks to auto zone and picked up 3' for cheap.

You can drive the car, it will likely trigger a CEL at some point, may make cold start rough for up to 90 seconds.

Since you changed the valve cover gasket, the hard part of the hose along the valve cover is likely broken and will need to be replaced all the way a back to the underside rear of the intake.

Get a new hose and you'll be set.

I did the same thing MPR77 did. I brought a piece, sized it up about right, and replace the small couple once segment. It worked fine. I did not start the car with the hose broken so I have no ideas of the codes that would be thrown if started while broken.

I think I am the only one here but when I purchased a normal vacuum hose from Autozone, it melted within a few days. So this is what I did when I broke my vacuum hose... I grabbed part number 11657803732 from the dealership. It is just long enough to run around the engine. With this, you don't need the rubber connectors since it is one long rubber piece that is high temp resistant due to the fabric wrapping. P.S.-I didn't need to zip tie it but I though the red looked cool.

I did something similar. I replaced the solid section and the flexible sections with a single piece of Teflon hose covered with braided stainless steel, that was rated to 400 degrees. It was a bit of overkill, but it got the job done, and I paid less than the $36 that a replacement solid section would have cost me. It is still working 2 years later. I liked the idea of eliminating the connections to the solid line, since it is just one more place to develop a leak.

@OP - You can't replace that solid piece with rubber hose, and still leave it routed along the valve cover, because the heat from the exhaust will melt it.

No, the zip tie is on there very loose. It doesn't need the zip tie, I just put it there cause I thought it looked cool.
