Hello. I finally found where my vacuum leak was coming from on my 99 convertible. But I am trying to find the small hose on the internet to buy and can't seem to find it. I tried using a regular hose and that isn't fully sealing because the original has a lip on one end. Any help would be greatly appreciated. It seems to come off the front passengers side of the intake.



I put new hose in but it isn't sealing correctly

Unless I'm mistaken; PCV

Yeah, check this out but maybe confirm with them, no pic so we don't know for sure

I think it is the hose going from the intake to the pcv valve. Correct?

From what we can see YES , could try your local dealer or cultrag if your not in a hurry

The PCV hose connects to the intake manifold just aft of the TB. Here's is the vacuum line schematic for a early NON LS6 engine and a picture of the pluming behind the manifold that frequently deteriorates and leaks:







Here is the vacuum schematic for a late model LS1 and LS6:

Flange end goes on manifold nipple:

That short section of hose with the flange molded onto it is not available as a separate item from GM. You can fab your own if need be.

Btw, CLEAN YOUR ENGINE COMPARTMENT!!
