? for those whom have taken the LIM off (N/A)

I was cleaning my 5th & 6th port actuators today.

It went half good half bad. I was able to get the rear one all cleaned up and working well (very smooth). I started to try and remove the front one and it all started going wrong.

I had to destroy the arm and rod assembly that goes into the LIM to get it out. Not a huge deal I hope I can just get one from mazda for less than my first born.

But then I was blasting Deep Creep into the hole cleaning it out. I had the little red straw on the can inside the hole and was blasting away (holding the straw with one hand / can with the other). I then procceded to shift my grip and off poped the straw and it went shooting into the hole . I wanted to kick the hell out of myself.

Anyway, My question is does that hole where the actuator rod goes into the LIM comunicate with the engine? Does that straw have the potential to fall into the motor?!?

Dude, this is where the engine gets its air from...What do you think?

Not a lot of room to shoot the whole straw into there, but I guess you did it, eh?

It's up to you to decide if you want to try starting the engine with a plastic straw in there. Best case scenario is it flops around with the rotor face for a couple of combustion cycles and melts away, or gets spit out...

Worst case...You kill a seal or two...

the actuator rod you destroyed is only $45 (mazdatrix). much less than a first-born child = )

it takes an hour or so to R&R the intake. Get the gaskets, and pull it apart. Might be a great time to have some new vacuum hose handy. You will find a few lines that are in sore need of replacement.

I'd take another chance and get some wire with alot of duct tape on the end of it and shove it in the hole you lost your straw in, it'll flex and most likely stick to the straw, might take a while to get it out but better than throwing your motor out. Oh yeah, if you got new gaskets for your lim did you get metal ones? I did last time, lot nicer than the older ones.

I dojn't know about some of the answers so far..............If that straw can be confirmed to be in the rotors you should not start it. What you should do is take off your exhaust and rotate the motor untill the staw comes around where your can grab it.

---------------------------------or------------------------------------

rotate the motor back and see if the straw pops back up into the hole

Above all else I certainly wasn't planing to start the engine until the straw is in hand. The engine is starting to get to rebuild point for compression anyway, Im gonna pull the LIM off and see if it is still wedged in the port or if it fell in. If it fell in Then Im part way to pulling the motor out and down to shortblock anyway so I'll just give atkins a call at that point.

I'm thinkin' that it would be really hard for that straw to go in and make that turn. IN the RA video and according the Pineapple the 5/6th ports do not flow very well because it is flat at the end and RA tells you how to modify the sleeves to help this flow......Now I assum that you did not perform this mod.....therefore that straw is probably stuck in the sleeve somewhere. AND not down in your engine.

You seem to be ready to rebuild anyway. So if you want this one as the reason to rebuild, let me be the first to reccomend that you do it know before you drop a seal and it makes it much more expensive once you damage a rotor housing.

You have to give us an update.

My point exactly. I also do not belive it would be very easy for it to enter the rotor housing through the stock aux port. I am afraid it may have made its way into the main port just below the front aux port. Being that I was holding the can from above the straw was probably angled down

no its not inside your engine, its just sitting in the sleeve. when you pull the LIM off i would get a gasket cuz they usually look pretty mutilated.
I did the same thing with one of my actuator rods. i have a couple extras but i believe they are just a little bit different from s4 to s5 and also from from port to rear port. get a close pic of the rod and i will see if i have a good one. just pay for shipping plus a buck or two

Well I apreciate all the replies. I'm going to take it apart tonight when I get home.....I'm not much fer prayin' but you can bet I am doing so right now I woulid like to get the summer out of this engine yet....

As far as the actuators. I am looking to get a whole LIM if possible. I know the actuator rods are sam front to rear on the S5 cars. I had my local dealership fax me a diagram with thier part reference numbers.....

Not sure if they are different between s4 & s5 but that would make sense as they work in reverse. Thus the fork would likely be rotated 90° or more from the s5 one.

I got the intake off finally. Straw was just sitting in the intake. I was almost able to get it with the LIM still bolted to the motor but not quite, so I took that off the engine. Since I have this thing all apart anything else I should do while I have it completly torn apart?

I have already:
Thoroughly cleaned the aux ports, actuators & sleeves.
Replaced as many vacuum lines as possible while all this is apart.
Replaced all associated gaskets.
Replaced the one actuator rod with new...

Anything else I should do? This car has no cats so i am considering pulling more of the emissions stuff off of it but I need the air pump obviously. Any suggestions?

Other intake cleaning suggestions?

dude, the actuator rods are not the same front & rear. are you sure you got the right one? I guess you are since you said you installed it, but you might want to triple check before bolting everything back on. I also have an s5 and I'm quite sure that my rods are different fron & rear. they even have little 'F' and 'R' stamped into them!

Yeah I saw the stamp and did find that the part numbers were indeed different.

It all went back togeater nicely. Only hitch at this point was as I was taking it apart I found that the mazda mechanic that changed the belts a few months back broke the the head off the tensioner bolt for the air pump (flush with the housing of the air pump).

Some Drilling & J-B weld surgury ensued last night. I can't belive i missed it. Unfortunatly, I can belive they did it and didnt tell me. Guess That is why my ports were stuck.

It also quit backfiring every redline shift. Now it only backfires when i make it backfire. (let off and stomp it)

I think mainly it realy finally let me reap the benefits from my Apexi intake and RB exhaust & presilencer.
