fixed my rattel noise, here is what it was
here was my original thread:
https://www.rx7club.com/forum/showth...hreadid=164866
The solution was adjusting the the TCA (turbo control actuator) arm/valve connection point. At full extention the tca valve was totaly closed, so it ratteled around in the turbo manifold. I removed the e-clip, turned the part at the end of the arm one full turn so that right before full extention the arm would be pushing the valve completely closed.
Booyaaa....no rattle.
Hope this help any of you other rattlers out there.

hey damian the TCA is the lower rod right? Did you completly remove the TCA unit? how did you get the rod back on the gate? i just took mine off and cant get it back on and i didnt even turn the rod yet ( since it is rusted, which is why i want to remove the whole unit)was yours tight like this?

thanks for all the help but one last question, are you sure its counterclock wise, because that would open the gate more when we are acually trying to close it all the way right? I can barely turn the thing..it takes me forever since its all rusted.. thats why im asking.

well, lets make sure we both think what we think we think :-) (hehehehe)
to my understanding:
the TC gate is closed normaly, then opens at switchover.... the TCA arm is fully extended normaly and then retracts into the actuator (opening the TC gate) at switchover..... so....
if your gate is 'rattling' around while at tilde (TCA extended, gate closed) then you need to extend the TCA arm a bit more to fully close the gate...rotating the end counter-clockwise (un-screwing it) will make the entire arm (end connector and arm) longer, thus pushing the gate closed further... so for what i did was adjust it so that the the gate pin and arm connector hole only lined up when I pushed the arm into the actuator a bit (only a few millimeters is needed) so that it kept constant pressure on the gate (closed)
make sence?
by the way, there is a locking nut behind the TCA arm connector, i had to break that darn thing loose first before i could turn the connector...real PIA!!! :-)

hwo does it get that loose? Did you guys use any thread locker once you adjusted it to make sure it doesn't happen again? Also any pics of exactly where this is? I'm ordering a workshop manual very soon. (BTW: where is the cheapest place?)

and this is the lower rod on the exhaust mainfold?
did u use a new e-clip or just put the old one back on?

As for a manual, I always just use www.iluvmyrx7.com when I need to access a manual. It's free, given you know how to open a PDF file.
