Hole in a rubber hose?!

[Magu]

Hi All,

This is my firts post and my first Cruiser, it's a 2.0 Dohc European Speced 2000/12 model since I'm from Sweden.

Bought the car 2 days ago and today I planned to change the plugs. But when I removed the plastic cover over the inlet runners I found a big hole in the rubber hose that connects the valve housing to the inlet manifold.

So my question is: Is this hole made on purpose? (It sure looks like it...) and if so why?! And if wear and tear has made it will this make my car go bad?

I attached a picture of it in this post so you can have a look.

Any help much appriciated.

Welcome to the forum.

We don't have that engine here in the U.S. but looking at the picture, I'd say you should replace that hose. It's probably some breather or emissions (do you have emission standards) hose that feeds back/recirculates air and the hole is just letting it out into the open instead of recirculating it.

Thanks CREWZIN,

So the hole shouldn't make the car go bad or better? I ask since I have quite a bad idle when starting and then it slowly goes down in incremenst to sub 1000 rpm. It's an automatic

And yes we have quite strict emissions, not as bad as in California but not far away.

You'll probably find your idle will smooth right out after replacing the hose. If you can't replace it right away, tape the hose up with some electrical tape to close up the hole.

Ha ha ha.. it worked! One meter of electric tape and the idle is silky smooth

Big thanks CREWZIN this is the quickest help I ever got!

Your welcome.

Don't count on the tape for a permanent fix, replace the hose.
