So am I 100% f*****, or is it no problem?<br/>A buddy of mine got carried away trying to help me do my valve cover gaskets

 

If you shove the hose as far as possible on the bore, you should have enough to keep it sealed.

Other options are a used TB or JB weld. And I'd be looking at some JB weld and some hvac tape to sculpt the missing piece.

 

Personnally I wouldn't trust JB Weld not to come apart and get sucked into the engine. You could try a junkyard or a new one from BBK.

 

I'd see if the hose would seal by pushing it on as far as you can. I'd avoid JB weld.

 

I'd put the hose back on and never think about it again.

 

agreed. shove the hose on to cover the hole, and forget about it.
