I had been chasing a vacuum leak for a while. Bought a smoke leak detector and I saw a big cloud of smoke coming from behind the smog pump. Is the pump bad? Is there a seal or hose on it I can replace to where it may be leaking? I just want to see what to look for when I get to taking it off to inspect. I’ve seen people say delete it and it’s fine and I’ve also seen some say it’s better with it.
Best video I could get:
