Intake Question



I know I'm STUUUUUUUPID.
I just said for now I'm going w/ bill because I have respected him since day one.
You may be right that >2001 there is no difference.
But until I've seen an intake I know is off a 2001 LS1 engine and an intake off a 2001 LS6 engine, I'm going w bill.
I know right now I'm assuming both the pics bill posted were off a 2001 (because my question is 2001 specific). They look different to me.
Maybe the pics he posted are not both off a 2001. Maybe the LS1 intake pic he posted was off a pre-2001. And the LS6 intake pic he posted was off a 2001 and later which may be all the friggin same on an LS1 engine and an LS6 engine.
BUUUUUUUUUUUUUUUT
My original reason for posting this question on this goofy thread is to know when I pull my intake off my 2001 to replace my oil pressure switch, can I get a better intake --- without spending $1000.
I've had my vette for about 4 months now. I know i don't know anything and maybe assuming too much. I'm not a mechanic, just a redneck with an awesome car. Maybe I should get a mustang... NOT...
Stupid signing off.





I do know this. If GM installed a 2001-2004 LS6 Style manifold on an LS1 engine,,, You will have BLOCK OFF Caps on the rear cylinder head steam vent bleed ports.
IF,, you have a 97-2000 LS1 Manifold, the rear cylinder head steam vent ports will have a small metal pipe that connect the two rear steam vent ports and a single metal pipe that runs from the rear vent pipe UNDER the manifold to the front steam bleed port cross over tube. The metal pipe that connects the two that runs under the manifold, will NOT fit properly under an LS6 style 2001-2004 intake manifold without either: 1. modifying the bottom of the LS6 style intake manifold ribbing OR 2. Removing the LS1 style vent piping and installing the 2001-2004 front cross over vent pipe and rear vent plugs.
When I did my heads and cam install, I replaced the rear block off plugs on my 02 ZO6 heads with a 2001-2004 front crossover pipe and connected the two with a rubber hose that runs down the drivers side of the engine next to the fuel rail.
Heres a picture of the head rear steam bleed port cross over pipe conversion:


It will give you an idea how big the small metal piping that runs under the manifold is. Sorry.. I do not have any pictures of a 97-2000 style steam vent crossover pipe set up..

1) what do you do with the large black hose hooked to the steam cross over in the first photo? Is that the hose you ran down along the fuel rail?
2) Since I've not done this yet is it not possible to use the steam crossover from my 99 in the front? Or do I need to start looking for a 2001-2004 front steam pipe?
3) Does my 99 have the steam block offs at the front of the engine?
again I haven't started this so I don't know what is under there.
Thanks!





IF,, your going to install a 2001-2004 intake manifold,, you have Three options:
1, Keep what you have and modify the BOTTOM of the new manifold. That consists of removing the small ribs on the bottom of the new intake manifold where the vent pipe runs under the manifold. That seems to work very well.
2. Purchase the rear block off plugs and install them in the rear vent holes and install a 2001-2004 vent pipe and install it up front. The pipe on the rear steam vent holes on my 02 is actually a 2001-2004 assy FRONT pipe.
3. Purchase TWO 2001 - 2004 front vent tubes and do what I did to use the front and rear vents.

So, for now I will take Mr. Curlee's because I knew after my first ever 30 minutes on corvetteforum.com that Mr C is the Corvette God. ( I'm not worthy, I'm not worthy.... ) Thanks, Mr. C for your post. I have learned much from the info you have posted on this site. So from what I gather, since I have the 2001, I do have the LS1 intake. I know now that when I replace my oil pressure switch and I put my intake back on, it is the best I can do without spending a grand for another intake (which was my original reason for this post).
Thanks all.
And I will enjoy. 
This was part of my confusion, too.

If we cant have a little fun on cf, then maybe the webmaster should remove the goofy smilies. Then cf would be about as exciting as an insurance web site.

If your replacing the oil sender I can save you many hours. Remove your wiper arms and cowl screen,now eye ball the oil sender and note its location compaired to the cowl above it.Take a hole saw a bit larger than the oil sender socket and drill a hole threw the fiberglass cowl directly above the oil sender unit, using a long pick pull off the wire connection on the sender, then using compressed air blow off any debris around the sender.I used a wooble extention and attached the sender socket, now put it threw the cowl and remove the faulty oil sensor/sender, place the new sender onto the socket,it will probubly fall off when trying to install the sender ,so take some masking tape and put some on the sender until the sender fits snug in the socket.
CAREFULLY start the sender unit into the block by HAND and make sure not to CROSS TREAD it,next try using mechanical fingers to place the wire connecter on top of the sender and using a screw driver push down and snap the connecter back on.
Next use some duct tape on the drilled out piece of fiberglass on the cowl and from under the cowl tape it on,now above that use some epoxy the fill in the gap,when dry give a quick black paint job.
I have done this method several times and it takes any where from 45 minutes to 2 hours depending on the person and tools being used.
I hope I helped you out. If you have any questions email me T51corvette@live.com

BTW, welcome to the forum.

The hint: The best and only intake GM offered in 2001
Do you mean the LS6 intake??
The suspense and confusion that insues in this thread is comical.
Confused... I'm not confused. I have a car, with a bad oil switch, and it has an intake that is in the way. I'm not sure that car in my garage is a Corvette or not any more. I better go & check to make sure.
I knew what you meant, tonyr. Some of these Sr. members & tech contributors are just hen pecked at home and have to take it out on someone.
Bill is a patient man, so I'm sure he will keep helping you, but you are certainly narrowing down the list of those that will.






You must be, if you completely dismissed what Lucky tried to explain. He is one of the more well informed members on this forum.
