96/97 intake swap pictures

[RedZMonte]

The trans vac line is a hard line that plugs behind the TB nipple. I actually capped a few of the nipples (didnt hook up evap crap and used original trans line w/ adaptor). Like i said i removed all the EVAP crap and simplified it a ton.

Let me see if i can find the pics or take a new one.. when the board changed over my garage pics went somewhere i dunno where..

here is how mine is: (all that is needed)
* Stock Trans line to the stock intake plennum adaptor (passanger side, just poped the freeze plug out and bolted the adaptor in its place)
* FPR and HVAC source plug to the connector on the intake arm w/ the brake booster hose
* Front Valve cover attaches to the nipple on the front side of the TB to the "L" shaped hose like in the pics from the swap.
The rest are capped.

You can run the '96 trans line to one of the ports on the TB if you want to do it how the '96 OEM setup was originally. My turbo setup got in the way so i ran the old trans line.

Thanks buddy. Pics would be great. I plan on ripping everything apart on Sunday and try for attempt 3 with the felpro gaskets. I will use all my sensors and my injectors which I know work. If it still does not run I think I will post a vid on youtube so you can see my setup and see if anything is missing.

So much for that plan. The intake met the fate of cracks. (long story). Does anyone have a 1996/97 lower intake they want sell?

I thought i saw a intake set on the FS section a little while back.. may wan to check and see if its still on there.

Thanks Guys. I got a new manifold after some digging. It is installed and my original issue was a stuck open injector. now that I have it all back together I have a misfire. I am assuming it is the same plug that the stuck open injector was on. hopefully when I pull it I will find it fouled. Going to replace all spark plugs and the j/y spark plug wires I used. Hopefully after this I can get back to driving her.

I have 3 cracked lower intake manifolds and another I can see on my spare engine. You would think my blower would be the cause but no and not even over torque the bolts the tabs on the cast are just weak. Gm realy messed up when they casted them. There is no streath to the bolt holes att all.

Really. They must have been made cheap. I tried to get a guy to weld it and he said he had never seen such lousy metal. I think the 20lbs torque might be a bit on these things. One this one I'm going to go only 14 - 16 Lbs.

Also they should do a recall on the 96 97 silver plenum outer bolts the ones with the studs on top. They only get half the threads the black bolts do and always end up striping out and being replaced with hili coils. I have just one intake that dosnt have a coil in it and the others weren't from be but multiple people.

i think the intake bolts are supposed to be tq'ed to something silly like 16in/lbs IIRC.

Yeah. I did 15. don't want to crack anything. Now only 1 issue left. Car idles 100% fine in park and neutral but in drive or reverse it seems like it's hunting for idle. But even after 10 minutes it doesn't seem to get any better. If I throw it back into park or neutral the issue goes away again Anyone have any ideas??

You may have a bad IAC try this. Year ago my IAC wasn't working that great it would often make the car sit at a traffic light at 3500 rpm. So when the engine gets to a good rpm in park unplug your IAC motor and go for a drive. I Drove my car for weeks like that and it worked perfect and the car ran good. It wont hurt any thing.

Tired that Dave and no go. attached a vacuum gauge and it shows intake leak. Not sure wht is going on here. Could it be the 95 heads are different from the 92 in the write up? I torqued 20 for lower and 18 for plemun as per the write up and still no go.. Any other thoughts anyone? Also I'm using Felpro gaskets for a 96 3.4.. Need help bad here.

Also using the 95 PCV valve if that matters?

and 95 thermostat.

Same gasket and torq. You sure your pcv line elbows are one piece. They dry rot and break often. Find the leak with brake clearer see if idle changes.
