Ok so I went to put new valve cover gaskets in my 3vze 89 runner. So now that I have it all back together I have a vacum leak and my car idled like crap I can hear it and it's coming from the jumble of vac lines on the passenger side, is there a common one people miss? Or does anyone know which lines go to what? Diagram maybe? But also now on the drivers side there is a awfuly huge oil leak. Can a vacum leak suck up oil or can one hooked up wrong pick up oil? Please any help or ideas? I'm gonna start again tomorrow morning and use a hose to hopefully pinpoint extacly where my leak is but that still wont help the massive oil leak. im starting to see why people dont like the 3vze what a pita

 

also i forgot to mention earlier is i also replaced the fuel filter. and it only runs rough at idle. anything over 1k it runs smooth. at around 1k or less it barley idles and the exhaust chugs. sounds like a vac leak right?

 

Bump anyone?

 

did u pinch the valve cover gasket? if your valve cover isnt sealing to the head it will cause the engine to run weird because its drawing in unmetered air
