All around intake manifold, usually. Even places not anywhere near where you were working can be affected from pulling on that and tugging on this. Old brittle lines are easy to crack and it's hard to see.

I'm not familiar with your engine so pardon the lack of specifics.

I recently tracked down a Leak to the drivers side rear wheel well which I thought had something to do with cleaning MI idle control valve..... It was just coincidental on the timing and not really related. Good luck with the search...... If you have any hair to pull out you may need to.
