The only problem I am having, is I can't get the vacuum hose that connects to the brake booster off. I moved the metal clip and I've been pulling on it for about 30 minutes. This MFer is NOT budging. Any advice or alternatives to getting this off?

This is the pic of what I'm trying to get off. This should be simple...but its giving me a hell of a time.

It's difficult, but it will come off. Maybe try and put a set of vice grips in it, not too tight - just tight enough to grip it, and try and get the hose to slide side to side. Its stuck on there from not moving for 10 years.

It can be a bitch I took a razor and actually slit it, not the best thing to do but no problems on my end so far and it worked.

dude, take a screw driver, and start on the booster side of the hose, and slowly try and pry it off, working the screw driver around the entire hose. be patient, but it will eventually come off.

stick a small screwdriver in there and pry it off. Just be careful not to puncture the line.

THanks for the quick responses. I actually thought of trying the screwdriver thing, but got side tracked when I punctured the top of my hand. I'll go try that in a sec.

3 cuts later, got it.

Any tips for removing the intake without breaking the OPSU. Which side is better to disconnect it from?

just be careful and lift up as you pull the intake out. I have never broken it and have taken off intakes a bunch of times

reach behind the intake and pull the brake booster hose over the sensor gently.

I'm glad you got the brake booster hose detatched. In the future, you could try a hair dryer to heat up the hose and then some visegrips or pliers to twist it loose. Good luck with the remainder of your install. =-)

since the 4 intake back screws cannot come out, I recently put 4 hand rags between each screw to hold them up. It was cake when I removed the intake. Like everyone else said, be gentle and patient removing and lift up the booster hose.

another way to hold the bolts up is to put a rubber band around the top of them, it keeps them from falling without a lot of **** in your way.

Its a lot simpler if you just pull on that hose & pop the vacuum check valve out of the booster with the hose connected. Then just pop it back in the booster when you install the new intake.

Next time, us a small screw driver or pick and insert it part way, then spray some WD40 or silicon into the opening and work it around. Spray more as needed and is should come off. You can also use one of the tool designed for Radiator and heater hoses, they look like a thicker ice pick but with a few bends in it (90Deg or so).

But just keep working it with WD40 or something, Even Carb Cleaner helps.

well, after a full day of work...I finally got the intake out of my car. I don't think I broke anything. It was hell getting the back bolts. I'm guessing my engine sits higher because of my solid motor mounts causing much more hardship. It took me around 2 hours and a pint of blood for the back bolts.

Now the funny part...I'm reinstalling my stock LS1 intake tomorrow, because of a mix-up from a purchase. What I thought was a LS6 intake, ending up being a 97-00 corvette LS1 intake manifold without EGR. Part # 12556333

Please, someone tell me this is actually a LS6 intake manifold...and that I read incorrect information from numerous sites.

Has anyone ever ran rich after installing LS6 manifold and ported throttle body? My idle is fine but it is running rich when driving at a stop oil pressure is back to normal.
