Sorting out vacuum leaks...

Post by my98s70glt »

I’ve been smoke testing my ‘98 S70 GLT today. Tightened some clamps, changed some hoses, then came across an exposed nipple on the intake manifold located below the braided line in the pic...

I watched a RobertDIY video and, I believe, he said a hose should run to the TCV from there. On my set up, the hose he is referencing is coming from the vacuum tree. Can I just plug the intake manifold nipple or does the hose need to come from the intake manifold to the TCV and I plug the tree?
Thanks
