6 PI Sleeves Temporarily Removed: Need to fix siezed actuator rods.
Last week I removed the intake manifolds to clean and fix the 6 Port Induction (PI) system. I made use of the Factory Service Manual (FSM) and two posts in the archive here.
The rotating actuator rods that pass through the lower intake manifold were siezed. Everything else was fine (execpt for lots of gunk inside the 6 PI sleeves - see the attached picture).
I ended up shearing off the lever arm (external crank handle) that the actuators attach to, and I was not able to free the actuator rods. I needed to run the car, so I put it back together without the sleeves. Here are my impressions:
4k RPMs and up have a nice power increase (easy to chirp the tires going into second gear). (Sorry, I've never dynoed my car.)
Low end torque has suffered a noticeable amount under 3k.
I fixed some vacuum leaks, and now my car idles much better.
Overall I am okay with temporarily having the sleeves removed, but I really want them to be working as they should. I don't like the loss of low end for around town driving.
Does anyone have a working series 5 lower intake manifold for sale or have any suggestions for fixing the problem. I could remove the rods by punching them out...

Go to your dealership and get them to pull up the part number, get 'em to show you the the parts look up screen or take the manifold with you, you can get the actuator rods AND the brass bushing that it sits in, and i think there may be some spacers as well..
you will have to use a press or a hammer and a deep socket (1/4 inch drive ones work best) the same size as the brass bushing to get it out..
I had to pound the hell out of the bushings to get 'em out, now I have a press, but don't have a car with 6-ports!!!!
get ready to **** your pants... those things aint cheap!!!

Thanks for the replys. I'm looking around for a used LIM right now. I found one in the For Sale section on this site.
I pretty much have to go with used parts. I don't want to invest tons of money in this car if I can avoid it. I'm already debating selling it and getting an RX-8 to replace my truck and car (daydreams about a new car with a warranty and no rust...).
As for the low end torque, I do notice it. One example is that in 5th gear at around 3k RPMs I used to be able to press the gas a little and gradually increase my speed. Now I have to floor it to get even the slightest acceleration.

i had one of my rods siezed in my intake manifold. i ended up bending it trying to loosen it and eventually had to replace it.
it is a part mazda sells, special order only though. i would bring the factory manual (or print out the page the part is on) and take that with you to the dealer. if i remember correctly, the rods are different for the right and left side.
