I almost forgot , your 2VZ-FE is a V6 right? (I cant keep track of all the alphabet engine soup names). There is a rubber coolant hose under the intake manifold. Toyota says to change it whenever the intake manifold is off for any reason. Might be worth doing it. Image of this hose is below, it is the hose between the two arrows pointing to "gasket" -while the upper air intake chamber is off, is there anything else i should check out?I'm removing the chamber to change the plugs and cables, and i'm checking the primary O2 sensor.anything else i should be aware of?
Wow this is late ^_^marc780 said:Clean the jheck outa the crud in there, you'll never get a better chance. I'd soak it in a bucket of simple green overnight if i could, scrub and rinse with water then blow it out with compressed air. Other than that, acetone works great but is dangerous as hell (flammable) but at least it's cheap. Or Seafoam.
