hester_prynne Posted June 28, 2011 Share #1 Posted June 28, 2011 I recently purchased a 1978 280z. I cant figure out what a couple things are. I have two pull knobs under the dash, on both sides. Driver side, its next to the hood release. Same location on the passenger side. I have no idea what this is...but it appears to be broken. You can still see the residue of the electrical tape the previous owner had wrapped around it. This large yellow tank has a small line going to it, but it is torn in half. Lastly, it came with aftermarket lca's and sway bars? Im curious if anyone can identify them from the blue color. Maybe a certain company uses this color blue as a signature? Thanks for any helps guys. Link to comment Share on other sites More sharing options...
5thhorsemann Posted June 28, 2011 Share #2 Posted June 28, 2011 The knobs are vents. Can't help with the rest, my car is a 240 and as such it dosen't have the other stuff. Link to comment Share on other sites More sharing options...
Arne Posted June 28, 2011 Share #3 Posted June 28, 2011 (edited) ^ What he said - the knobs are for the footwell vents.LCAs look stock to me, looks like someone liked blue paint. Edited June 28, 2011 by Arne Link to comment Share on other sites More sharing options...
FastWoman Posted June 28, 2011 Share #4 Posted June 28, 2011 (edited) The thing on the throttle body (with electrical tape residue) is a dashpot, used to slow the return of the throttle. It's not necessary, but it does help. Contrary to appearances, nothing connects to the crumbly plastic cap. The translucent bottle in the next picture is a vacuum reservoir for the HVAC system. The vacuum is used to control the high idle on the engine and the various doors and workings in the air handler. Yeah, stock on the suspension -- with nonstock paint. Those vents are one of the "cooler" (no play on words) parts of the car, and yet I forget to use/enjoy them. BTW, there's no reason to be clueless about these things. You can download a copy of Nissan's Factory Service Manual at: www.xenons30.com You can also buy a paper copy used on Ebay or Amazon from time to time. Good book -- well worth the money.

Arne Posted June 28, 2011 Share #6 Posted June 28, 2011 Maybe. The swaybars could be aftermarket, but the LCAs are not. Link to comment Share on other sites More sharing options...

240ZGL Posted June 28, 2011 Share #8 Posted June 28, 2011 Sway bars are factory, tank is a vacuum tank, get some more vacuum hose and follow it. Link to comment Share on other sites More sharing options...
