70 Nova TCS Relay

[JRSully]

Ron, that is probably what I will do, my only problem is that I have a beautiful NOS TCS vacaum set up, don't feel like ripping it apart, does it come apart.??? or should I get a repo or used one.??? Thanks

Sully,
If you have old NNN issues, go to June 1997. On pages 14 and 15 it shows how the unit comes apart. I didn't take mine apart so I can't tell you. I know you have Jeff's number so you could call him. It doesn't look that hard. Looks like you just have to push the crimps on the cover open and it comes apart. In the article it said they did not reinstall the plunger and spring therefore making the solenoid a vacuum canister. Hope this helps.

Sure does Ron, I will let you know how I made out when it comes time to do that, I will be quite happy, as the car will be almost done at that time. Thanks again

I have the complete system working on my Chevelle.It actual improves my Gas Mileage.
Why not just take your system off instead of trying to look correct??
If you as the owner do not care for it,why should a
carshow judge or anyone else tell you what is missing.

The Shadow Grey L-78 NNN Nova that Jeremy Newton won here in Illinois in the 90's did have it working when he sold it recently.Can't say as I blame im as he sold a ton of those Raffle tickets for the NNN,then kept one for himself...That was the winning ticket.
He showed it with me at Local carshows,then used it to finance his way to College.

I have seen some original TCS systems that use a tube from the selonod to the back of the Q-jet carb which was for clean filtered air for the TCS selonod. Many of the restored cars I see have this line missing but the tube port is there on the back of the Q-jet. Not sure if they all should use this line to back of carb in addition to other lines for vac advance.

Actually, all you have to do is just re-route the vaccuum lines on the intake's TCS switch so they bypass the solenoid. I have all the lines on there, but for street driving, I just bypass the TCS, then put it back for the shows. Or, some owners just drill the solenoid through, thereby you always have the vacuum signal.

You also need the 4way tee that links the carb, solenoid, & A.I.R. pump. Wayne, Stan, and I worked on Belky's orange deuce's TCS system a few years ago getting all the lines figured out.

Marlin/anyone,
Are the 4-way tee connectors available from any of the major resto suppliers? I found one at the local NAPA store in a somewhat accurate color but it takes some work to get the moulding details correct. Had to trim away some of the flashing between the nibs, etc. Also would be interested in some detailed shots of the correct routing of the hoses.
