Time to stop asking questions and just get to work. What if what if what if isn't going to get this done.

If you damage the gears, you'll be the first ever. Just get the thing off the car and open it up.

I know I'm annoying at times with all those questions. You aren't the first one to point it out,but in the end it pays off when I start doing job instead of going back and forth to PC and start asking again.

My deepest apologies.

Hey, Will
Don't get mad but one more question.
Does it make sense to replace manifold gaskets while supercharger is removed?
Is it a lot of additional work?
I didn't want to start new topic just because of this little question.

yes. change both the upper and lower intake gaskets, and the 2 o-rings that are at the tb side of the sc.

now, get to work, take the sc off, and post pics of the results.

ps, dont forget to relieve the fuel pressure by disconnecting the neg battery terminal, and releasing the valve from the fuel rail to a rag.

and you should also lower the coolant level to below the LIM, or empty if you choose.

Well,I'm not sure about pictures.
I'm doing this on a Brooklyn'* street so generally have to watch if any bum steal my tools while I'm under a hood A lot were passing by with clear intention. lol
You mention upper intake gasket. I think it'* a SC gasket and two manifold gaskets on supercharged engine.
Correct me if I'm wrong.
Just to make sure everything is in place.

if you go to the parts store, it will probably be listed as a upper gasket. but yes, technically it is the sc gasket. and then two symetrical LIM gaskets.

Thanks for info.
I will try to make some pictures.
I still undecided either to change those gaskets or not .I will know after removing SC and check how much of additional work is it.
I'm very short on time.

Over and out.

It'll cost you an hour extra total. It'* very easy while you're there. And replace the plastic bypass fitting in the LIM with a new metal one.

Don't go in there and work without changing the LIM gaskets.

I think you are right.
Would be to stupid to have everything removed and not to change LIM gaskets.

Two questions:

1.Where plastic bypass fitting is located? Trying to find it looking at FSM pictures.No luck so far. Probably goes under diff name. Dealer has the metal one now?

2.According to FSM :..to complete the instalation......Apply GM approved sealer to the ends of the manifold seals.
Can you explain more detailed how to do it?

Thanks in advance


EDIT :I think I found where coolant bypass is located. Is it in front of engine (where water pump is? If yes,I think my bypass is a rubber hose. At least something similar I saw when changing accessory bracket.

Under the rubber hose is a plastic threaded fitting. Remove the hose to see it. Get the metal replacement at any parts store.

Quit worrying about the goop in the corners of the LIM until you're ready to put it back together. If you buy the Fel-Pro gaskets, they come with the tube and clearly explain how to use it. Basically you put a little dab in the corners where the heads and block meet, place the gaskets (4 pieces), then another little dab in those corners 'bridging' from the block end seals to the LIM gaskets, then place the LIM.

You could have it completely apart by now.
