Intake pipe...

Diablo, take a picture, and prove to us. I think you have it mixed up in your mind.

I need up upload pictures of my 3500 plenum setup. I used all the 3100 emission lines except for making my own trans/vacuum ball line, and FPR vacuum tube with rubber tube. I later added an elbow back to the top of the FPR so it looks really close to stock unless you get close and see it's rubber lines.

Funny, my rear breather tube actually fits BETTER and stays in on the 3500 setup than it did stock.. Stock it would always pop out, but now it's held in better because the intake hose is angled differently due to the 3500 plenum TB neck comes out farther and at a different angle.

Diablo, you see, in this picture, the pcv? The tube attached to it plugs into the top of the plenum and T's off to the EVAP Solenoid. It does NOT go into the rear valve cover. Now, do you see the fitting coming out of the silicone coupler just to the right of the throttle body? That line runs all the way around to the rear valve cover. It has nothing to do with the PCV.

maybe i do, its been a long week and i haven't been out to the car in a while, even then its torn down, duno why i said a rear pcv

sorry for any confusion, just trying to recall things how they are on my engine, i dont believe i have the breather line either way though.... maybe its just my sleep deprived mind thats finally getting to me though...

Don't know if anyone cares still, but this is the 1993 3100 SFI ducts that I use in my 1988 Cutlass Supreme.





Biggest advantage is that it does not have the muffler like the 1994+

Cute dog! The airbox's identity was protected in these photos haha.

For my airbox I'm still trying to figure out some cheap but decent flexible hose in 2" diameter. I'll run 2 of these down somewhere cold to give my airbox more openings to air. That or I could do a 3" possibly if I found some 3" thin wall ABS pipe to weld to the box and run a long air tube from like a truck air cleaner or something.

The dog is annoying. He is my uncles. His name is CROTCH-SNIFFER. My uncle named him BANDIT, but seeing that he greets you with a cold nose to the groin, I call him CROTCH-SNIFFER.

I had my aunt and uncle rolling in laughter. He kept nudging me down there, so I finally grabbed him, pushed him onto the ground, kneeled on him so he could not get up, held his head down, and yelled "DOWN CROTCH-SNIFFER!" It kinda stuck with him.

I need to protect the identity of my airbox. It ratted on my engine and my engine got busted, so it is afraid the engine will seek it out for revenge.
