[doom26464]

exclent that should be good I went and bought 2.5 inch diameter rad hoses, so I think this should turn out good hopefully.

 

[shaeff]

yeah, just make sure you use some good hose clamps on there to make sure there's a good seal.

Nice writeup. Someone should post that link in the FAQ.

 

[doom26464]

it is a good write up I'll tell yah how it goes when its done. only one thing holding me back right now trying to find a big enough drill bit to get the vavle stem in.

use a small drill, then open it up with a pocket knife a little bit, then a round file!

yeah but u have to make sure the valve stem fits in perfect or it will leak air. then it will all be a waste of time. My dad has some big drill bits but i'll have to wait a day or 2 for him to get them 2 me. I can wait though patience is key. Kinda Stocked though hopefully this well be the end of my problems and it will tell me if i have boost leaks or not. one less thing to worry about on my mind

I used a tuna can and put the valve stem in the bottom of that. I think it was the 6oz. Fit perfect on the end of the accordion hose.

FYI,

You can also duct tape a shop vac hose to it, turn it on, light a cigar and blow smoke on all the connections.

 

[doom26464]

well got a big enough drill bit and now the boost leak tester is complete hope to try it out after work :icon_surp

My CT26 turbo inlet is 2 3/4" O.D. If you are purchasing hose by O.D., get 3"

Good luck getting 2 1/2" to strech over it.

As for the tuna can in the other end of the accordion hose. I would not want to test if my crankcase was capable of holding 20psi. That is asking for trouble.

yeah thnx for the info kinda late though. I just got everything in the car apart like 10 min ago and now I find out my hoses is too small. So now I have to go back to store and buy new hose and a plug.

 

[doom26464]

actually my dad just came up with a good idea. I wraped the end of the hose in electrical tape so that now its big enough to fit in the end of the accordian house. So now all i got to do is plug all the plug into the accordian hose and run it from there. This is even better as i can check the accordian hose for leaks too.

Um... That's a bad idea. The accordion hose is not on the pressurized side of the turbo. It's designed to see a vacuum. There are hoses connected to it that you don't want to send pressure to. Like the PCV valve.

hmmmmm i was wondering that as well. I guess i can just plug the holes with rages or something then.

 

[Dirgle]

If you have rubber stoppers to plug the holes then maybe, but rages are not going to help you any. Your best bet is to just go and get the larger hose and do it the right way the first time.
