I've searched and found that alot of peoples 5th and 6th ports arent opening but I think mine are stuck open and I have had them off and greased them and can push them down with my finger just wanna know what I should do.

so the actuators work and rotate the sleeves?

Well they are in the up or out position and I can rotate and push down the rod but it wont do it on it's own. by reving and I did the grease test by putting grease on the rod and driving and No marking on the grease to show that the rod has moved at all.

Yup that can happen. :-/ Best thing to do is get a copy of the FSM, a nice weekend, and carefully take off stuff until you can pull the actuators off. If you can't turn the sleeves by hand, you need to pull them out (requires removing the lower intake manifold - I did this as a n00b, very carefully, and was very successful and clean them up, maybe use some steel wool on the burnt oil. Then lube them up with some motor oil or maybe WD40 (I think I used both, heh) and put them back in and make sure they turn nice and easily...

Then test your actuators carefully with either low pressure (2-4psi or so) compressed air) or pull them in and out with your hand and see if they move around.

Put it all back together. Oh, and while its all off its a great time to replace those crappy vacuum hoses with Hose Techniques silicone. Change your oil, check your radiator hoses, etc... while you're down there too.

I don't think there's any point in lubing them before reinstalling them, but anyway... I'm partial to spraying the hell out of the sleeve passages with carb cleaner before reinstalling the sleeves.

amur, i hardly ever see you on 2nd gen forum?

Is there a writeup on this somewhere? With pictures and all? I have to do this, so if there isnt already a writup, I'll eventually make one.

Sorry if I misunderstand your situation but "pushing down the rod" means to open the port on S4 cars.

Take the vacuum line off the supply line for the auxillary ports. Put a long piece of vac hose on that nipple. Blow like the didkens in the vac hose. The acutators should retract. If they don't.......and you said that they moved with finger pressure.......then you have a air leak at the body of the actuators. It's as simple as that. Or you've plugged the small air passage that feeds the actuators.

And like the man said, a series four opens when the actuator retracts.....and it closes when the rod is fully extended. Your post indicates that they are indeed going fully closed.
