My 5th and 6th port actuating rods got replaced from a new (used) lower intake manifold. I go to bolt it up and everything is turning smooth, the second i tilt the manifold they bind and cease to move. The manifold is just hanging on the two lower studs, when i simply tilt it forward a freakin 1/16" to make it flush they both just bind hardcore. WHY?????!!!!!!!! This is making me so ******* mad. Do the old bushings from the other manifold need to be swapped over to allow the rods to turn smoothly? Assuming they have worn themselves into place? No matter how I torque the bolts to hold the manifold on i get the same 'stuck result. I took a flatbar to the engine and the manifold and i had a tad bit of gasket remains around the right stud, i scraped it off better thinking that would help level it out and no luck. I spose i could swap in the new (used) manifold, but then i would have to take off the oil injectors, the new acv blockoff plate uhhhhhh what a pain. I am really limited on time, ANY help would be thankful. ~Gavin

 

try just taking them out and see if you like it...

If the loss in low end torque becomes a concern, continue to try and fix them.
