Thanks guys but im thinking i may bite the bullet and get a k&n fipk..

its $231 shipped at autoanything with coupon code.

Im just worried that my temporary fix will eventually crap out again or leak air later on.

 

Nothing personal, but that's a stupid fix, unless you wanted one anyway. I broke mine about 10 months ago & used plain ol super glue. It hasnt broken since, just make sure to warm up the plastic hose with a lighter to soften it before taking off & putting on. It won't crap out later on, I promise.

 

Superglue isnt working. I tested it by breaking it off when it was dry to test the strength. It was weaker than a pencil. I tried regular and gel.

Im not risking that thing breaking off in the middle of driving

 

go to harbor freight and buy a cheap plastic welder and put it back on

 

Thanks for all the suggestions guys. I decided to go with a more long lasting fix. I bit the bullet and got a k&n fipk.

Hurt my wallet pretty bad at this time but i got a break on a side job so i have some $ coming through.

Thanks again for all your suggestions! Maybe someone can learn from this thread another time

 

well when you super glue you have to clean the parts that youre gluing together.

but then you can bypass that stuff i think

 

Here's my story that led me to this thread. I went to clean the throttle body and while taking off the vacuum box/air duct assembly, I heard a little crack. Upon inspection, I found the broken nipple. Just one thing. It had already been glued back together. Not by me. I've changed the plugs, and took it off with no problem. But a couple years ago, I needed a starter. I made the mistake of having Lexus of Austin do the work. Besides putting in a bad starter, they cracked the crossover pipe and tried patching it with putty. It leaked and I caught them. Apparently they also broke off the vacuum box nipple and glued that back together. So now, I need to fix or replace it. When they glued it, they also glued the nipple into the hose. I'm going to order a new hose and take it from there. I noticed that I was able to start the car with the hose completely disconnnected, so I'm thinking the connection doesnt have to be perfect. I tried a few glues, but Barges contact cement (which I use in my sheathmaking/leatherwork) seemed to work. I do want a better fix for the long term though. I'm ready to set fire to my Lexus dealer though. (jk of course) I'm thinking the brass nipple glued in place is the way to go.

 

Anybody know what the vacuum box, intake duct part costs?

 

Yup--these things are brittle. Broke mine off, too. I borrowed a tap from work, and tapped pipe threads into the box. Screwed in a brass nipple using epoxy as a threadlocker. Worked like a charm, and solid as hell.

 

It cost enough to the point where you might be better off buying an aftermarket intake instead lol.

17875-50170 There's the part number. MSRP $327.73

 

UPDATE: Went to Lexus of Austin to order the hoses I need.. one tore when I was putting it on after the throttle body cleaning. The one by the broken nipple needs to be replaced because the dealership glued the plastic piece, box and hose all together. No way to salvage the hose. They had a heck of a time figuring out the parts diagrams and finding the right hoses. Finally printed the diagrams and had one of the old pros go out and look at the car. Turns out, his family used to own a carb rebuilding business. When I told him what I was going to do, he agreed that the brass nipple was the right way to fix it.

I complained that I wouldnt even be doing this if the dealership mechanics hadnt broken it during the starter replacement a year or two ago. They got the service mgr, who remembered the incident, because they also put in a defective starter and broke the crossover pipe. He offered me all the parts at cost, including the box/duct assembly and any assistance I need when I do the repair. I still think I'd rather use the brass nipple fix than replace the whole assembly. That nipple would break off eventually on the new box, and I'm sure that cost is still higher than the cost of a brass nipple and a tap.

The parts guy also added that the second generation GS is probably the best car lexus ever made, and should run forever.
