3VZE vacuum leak on passenger side at rear of motor

[kc15842]

Folks,
I'm considering buying a 92 but it runs like crap and I can hear hissing behind the passenger side valve cover. Idles fine but big time hesitation, its much cheaper to drive it vs. towing. Any ideas?

Goin through the whole thing myself

I'd look in the pair/reed valve area... See if the hose is cracked/brittle.... And also run the diagnosis test of it....Then I'd look at a vacuum hose diagram and make sure everything is connected and not leaking...Especially on the backside against the fire wall. I have a 93 3vze that I've been doing a through tune up on over the last week due to it running rough....Replacing a LOT of stuff.....

I did notice the small line on the charcoal canister off and I think that routes to the TB. But its not the main leak, Thanks!
