Default Ls6 intake install

http://www.ls1howto.com/index.php?article=5

Holy crap...is it this Complicated or is it just very detailed and i am over reacting?
Also do i need lube/grease for the intake gaskets and injector orings?
I bought the coolant cross over from ws6 store so that should be good....
But yeah...someone said something about a new knock sensor?

It's not that difficult, just go slow and take your time. Make sure you reach back behind the intake and disconnect the sensor and the small vacuum line before you yank it out.

When your pulling it out, reach your hand behind it and guide the rubber hose that goes to your brake booster over your Oil Pressure Sending unit or it will break.


You shouldnt have to lube your injector O-rings unless your taking out your injectors

I made the install video. Unfortunetely the first half was lost but I still have the second half which is my removing the fins on the bottom of the intake and re installing it. It's very simple if you follow the steps on the howto you listed above. Just take your time, have a couple cold sodas/beers and play some good music. You'll be done in no time.

It really is quite simple. You will realize it when you get into it. I use a very small amount of dielectric grease on the injector o-rings so they slide on with easy. You don't need to replace the intake manifold gaskets if they're still in good shape. But they are cheap to replace. Same goes for the knock sensors.

That LS1howto guide really makes it easy. Like TheBlueKnight said, have yourself a few sodas or beers handy, some tunes and have fun with it.

what do you mean? if the intake is already on your car why would you have to chisel it to fit?

One trick that helps GREATLY that is not talked about in that link.....when you put the intake back on they say to put the 4 back bolts in, then HOLD them all UP as you put the intake into place. YEA, RIGHT.

Put those 4 back bolts in, lift them up so they are not sticking out of the bottom at all, make them even on the bottom. Just before they stick out. Then take a 2 inch long piece of masking tape and tape each of the bolts in place on the top.
Then you can effortlessly slide the intake into place, then down into position. Then one at a time...take the tape off each bolt and drop it into place and thread them in by hand at first. Then you can drop all the other bolts in and tighten them all down.

Iirc, the chiseling is to accommodate the oil coolant lines of the LS1 system.

I would strongly suggest changing the intake manifold gaskets as they are a "crush" style gasket. When you do the install you will see that the head side of the old gaskets will be almost completely flat. Lots of guys skimp on the $20 for new gaskets and end up with a vacuum leak they cannot identify.

That's a great suggestion. To the OP, if you don't have any tape handy, rubber bands or zip ties work great as well.

No kidding. I bought a supposably slightly used LS6 intake and the gaskets surely looked ok to reuse. They weren't flat, not like the old ones on my stock LS1 intake, those were a hell-no-way to reuse. Well thanks man, lesson learned. Thank goodness its easy and only takes about an hour to change them out.
