The 2nd is (or should I say was) a smaller 5/16? Steel tube coming forward from the center of the plenum above the lower intake. I grabbed the black vacuum cap to pull it off and the tube immediately came off the plenum. It looks like there is still a piece in the plenum. And the tube looks to have been broke for awhile.

I also see some other interesting things.
I believe this orange and black/wh are the EVP or EGR wires? Electrical tape wrapped around it with what looks like a cap of somekind?

a1machinista1 · Nov 12, 2023

Cut vacuum lines... I'm assuming this is part of the EGR or smog pump system?

Also I found 3 coolant sensors.
Factory on drivers side IM.
T sat housing aftermarket temp gauge in cabin.
And this one in IM above Tstat. Any ideas?

I did confirm I have Cats with 02 Sensors. I have them but that is ALL I know

So it looks like my new to me car is going to be parked for awhile... I was really hoping to be able to drive and tinker at the same time. But I guess that is just not going to be the case...I think I will pull the plenum to fix the tube. I think I'll try to plug the hole and smoke it first. I'll figure out what injectors I have while I'm in there and make sure they are optimized.

That looks like a 2.5 catted x pipe. If it's stainless you are in luck, that's like a $600+ pipe (evennif it's not ss, you are still good). The injectors look like 19s, which is fine for that setup.

I have access to the injectors on my wrecked car I gave away. They were rebuilt and have maybe 100 miles on them.

Temperature sending units. One on driver side in the coolant crossover on the lower intake is for the gauge in the instrument cluster. You said the one in the thermostat housing is going to the aftermarket gauge. The one in the intake just behind the t-stat is the ECT sensor which goes to the ECU.

a1machinista1 · Nov 12, 2023

That makes sense, I don't remember that one there on my last car... I was kind of hoping it would be some Telltale sign of something?

You just need to pull that upper and fix all those vac lines, the vac lines for the two solenoids will have a main line (black plastic) just cap it for now. Check the plastic line that runs alone the firewall by the pinch weld too, then smoke test.

a1machinista1 · Nov 12, 2023

If you're talking about the Hvac line to the check valve? That is gone and capped off at the manifold (plastic) I still have a line thru firewall to hvac and thru fender to reserve ball. Most of the lines at the two solenoids are cut or plugged.

a1machinista1 · Nov 12, 2023

I just put a rubber stopper with some ultra gray in the hole. Once it sets I'll smoke and see what I find. I have to start it up to move it to the other garage so my wife gets her spot back. My rebuilt injectors are on the way. I'll get this torn apart after I finish the tile work.

Thanks General

I don't understand why someone can't pull lines and/or cap them instead of cutting? Hopefully the smoker won't blow that plug...

a1machinista1 · Nov 12, 2023

OH, also noticed this which I'll have to deal with. Hopefully not a sign of a serious issue.

General karthief · Nov 12, 2023

Get ready to replace the pcv valve, hose and screen.

a1machinista1 · Nov 12, 2023

Any upgrade or improved set up for this?

a1machinista1 · Nov 24, 2023

Ok, back on the car. Tile floor us done enough to move forward. Plan today is intake removal and fix. I did notice the factory BAR sensor has no vacuum to it. Ant thoughts as I start wrenching?

a1machinista1 · Nov 24, 2023

Well, besides the front vacuum tube that broke off the plenum when I pulled it off I found this tube laying on top off the lower intake in the back by the PCV
