Ok . . . I have read just about all of the FAQs, looked at every diagram I could find (can you say emersed) and even signed up for Alldata on a 2002 Camaro so I could get lots of info on my motor.

So I go out to the garage with all of my new knowledge and look at the plastic fitting in the back of the intake that houses the MAP sensor and I notice 2 hoses coming from the fitting, a large (5/8") and a small vacuum hose that "t"s off to another small vacuum hose . . . . back to Alldata. Now I have looked at every diagram that even comes close to the rear of the engine . . . . nothing. BTW the large hose has a 90 degree one way valve on the end of it (looks like some PCV valves I've seen).

So . . . . . can someone help here with the satisfaction that he is more knowledable than Alldata.

Also . . . I wanted to start with something easy so I thought the re-routing of the cooling hoses attached to the TB would be a simple mod . . . . turns out my TB doesn't have any cooling hoses attached . . . in fact no cooling hose fittings on the TB . . . . should I be concerned ??

Thanks for the never ending help.

look at the coolant crossover pipe between the heads, it runs along the front of the intake under the throttle body from head to head and see if there is a hose running off of that possibly straight back to the radiator underneath the radiator cap

Tubes/misc that you will find in the back of the intake manifold

-Brake booster hose, prob the thickest hose you will find, should snake to the drivers side of the firewall, about 12~16" long
-Small T fitting for manifold vaccume fittings, include AC vaccume hoses, and potentially one more.. Fuel solenoid I think... fitting should be on the pass side of intake, near the back.
-MAP, on the direct back center of manifold, flat sensor clipped into manifold by a pretty thick tab.
-Knock sensor wires, run out from underneath and rear, attach to bracket that is mounted on the manifold near back of drivers side fuel rail.
-Drivers side valve cover starting of PCV system, there is a 90* fitting that comes out of the drivers side valve cover, snakes over the rear of the manifold, and along the pass side, splits into two, and connects to PCV and then TB
-Oil sender sensor unit, drivers side rear of manifold, very fragile, sticks up very near the brake booster, no hose or cables coming off of it, but it is a force to be reckoned with to say the least.

That's all I can think that's in the rear

There is a metal pipe right under the TB that is capped off. Thanks. Now I know where that hose goes when the radiator gets here.

Geez . . . . I should have known that, now I know where I've seen that one way valve before.

Thanks for the rest of the walk through John, much obliged.

Alldata is great, but it is nowhere as comprehensive as the factory manuals, search "helms" on the web, they are the publishers for the factory service manuals for GM, you have to buy it from them. All three volumes sell for about 120-150 range, there is also a guy on ebay who sells them. Watch out for those CD based manuals on ebay, every one I have seen is missing stuff that was copied from the manuals.

righto,
If you haven't seen it already. Checkout the article --> here <--.
It's a very good install document on the intake swap, even if your not swapping it ID's a lot of the parts with pix and such.
very helpful, install university rules.

Helms it is. Thanks Mike.

John: Missed that article because I have the L6 intake.

Ok . . . radiator (custom piece) doesn't have an inlet for the hose that used to go to the TB. Can I block it off with out frying the motor??

Thanks for saving the bacon again

The title of this thread is comforting, let me tell you. I'm glad I'm in the Delmarva area.

The only reason coolant flows through the TB is to keep the blade from freezing shut in very cold weather. Many people have it bypassed, including me, in hopes it will help lower IAT's. After you get the LS1 installed, take the car to VIR since you're in VA, great track.

Did you say VIR ?!?!?

Constructive (or destructive) criticism is welcome.

If your radiator has no provision for the TB coolant return line, just plug the outlet on driver side of the metal crossover to close it up, it will not overheat the motor. However, that outlet serves as a bleed off for air from each bank for the coolant passages. Try to connect it to the puke tank securely to keep its function. Dont worry about the inlet and outlet on the TB you can plug them with vaccum caps to keep debris out but it is not necessary.

Thanks Mike. I'll run it to the over flow, which is connected to the tank, as suggested.

Nice driving, the Oak Tree can be a pain.

post some pics when you shoehorn that thing in there.

Thanks guys . . . yea I cooked Oak Tree one time trying to catch an RSA.

I plan to document the "shoe horning" in the Hybrid section to be forum appropriate

I was thinking over what I said in post #12, and now I think connecting the line to the puke tank could be problematic, since the crossover is a constant flowage, and the puke tank relies on suction (I think). This means the flowage into the tank could be faster than the flowage out. Hook it up to the radiator directly if you can

Thanks Mike. That's exactly what I did, thought it might work as a bleeder for the engine when filling the system.
