I was trying to get my bypass valve out today and I was a little bit rough with the intake tube trying to get the air horn out. Didn't hear any cracks or anything and the tube feels secure but now I'm paranoid. Is there anyway to check the intake tube is okay before I put everything back together and try to start the car? Will it be obvious if I broke it?

 

Yes it will be obvious. The thing which breaks often is the thingy where the bolt goes in. I broke mine when I refitted it. The most important thing is the green gasket. If its broken, it will suck in air, which will make the car run lean. If you have something like Torque Pro (android app), you can see and monitor fuel trims. If it needs to correct more than 10% (over or under), then something is wrong (over- or underfueling)

 

Ok I finally got the airhorn out but I think I might have actually broken the air intake duct now :( I pushed it down and it felt like it slide down a little bit smoothly, didn't hear a crack, but it does wiggle now, not much but it does. Is that supposed to happen?

 

Okay update: Put it all back together and the car runs great! No issues other than accidentally shearing one of the throttle body bolts, a problem I'd much rather have than the intake tube.

 

Its time to stop the doomsday thinking
