I made this tool at work to check for intake leaks and leaks in the vent system.[/align]Some people will by Fog machines in shops that will do almost the same thing.[/align]This is only a picture of the tool and a small idea of how to use it.[/align]This can only be used with a air compressor.[/align][/align]So I got the round plastic cap looking thing from a New fresh air hose that was purchased from the Dealer for a Customer.[/align][/align]Then I got a pressure regulator with a gauge on it.[/align]Also got some couplers that matched the air lines at work.[/align]I installed the couplers on the regulator first. one female and one male so it can be installed inline with the hose.[/align]I than took the plastic cap and drilled a hole in it. I drilled it small enough that the coupler could be screwed into it.Then took a female coupler that had female threads in it rather than male threads and screwed it on the male part of the threads on the cap.[/align][/align]Then when you need to check for an intake leak or boost leak you can remove the induction hose from the massflow and slide the cap into the hose and clamp it in there.[/align]Then remove the oil cap.(I loosen the cap and stick a rag between the cap and motor to prevent splattering oil when the cap vibrates)[/align]Then plug in the hose to the regulator setup.(Make sure the regulator is turned all the way down so no air comes out. Then turn the regulator up to about 3 PSI 4 max.[/align]Then listen for leaks. If you can't hear anything leaking get a bottle of soapy water and spray all connections looking for bubbles.[/align][/align]Fix leaks as needed.[/align][/align]Here is the pics of the tool.[/align][/align][/align]

 

Nice

 

Thanks

 

Are you a millionaire yet from that one?

 

Nope!!!

 

better get a patent and contact lisle

 

Man, I swear you're McGuyver (sp?) of the Volvo World. You make more tools to work on cars (and they freaking work) than anyone I know! You should be rich off those tools!

 

LOL I wish I could do it!! LOL

 

+1..... I think you should get a pattent for half of those tools.....

 

But it still takes $$$$ to get one!! LOL
You know what they say it takes $$$ to make $$$!!! LOL

 

hey tech, i made the same tool today. I have p0455 code, gross vacuum leak. Is it ok to plug this thing to one of the hoses at purge valve and look for leaks?

 

You have to keep it at like 2 PSI and let the pressure build some then pinch it off and look for the leak.

 

sweet tool something i have thought of but never made. glad someone has done it with success!

 

It works good I use it all the time. Good luck making one.

 

Oh good post and i will try it as there is some leaks in the vent system of my car too and will tell u it is helpful or not.....

 

Thanks!

 

I will stick to my smoke machine...rig the smoke machine up, look for smoke, pinpoint with some shop air and a flashlight.

not bashing you, but what you made is well done. One improvement I see though instead of using a adjustable regulator, why not adapt a fuel pressure regulator, one of the set range type 3-4 PSI. use an adapter to adapt the fittings. I could see getting those ***** turned, and blowing seals out.

-------

edit: sorry that was half baked. Shop air at ~80 PSI, would destroy any other type regulator, forget my fuel pressure regulator idea.

 

Yes that could be a better way to do it. At the time that is what I had. Also the reg was really tight. Also once adjusted to the proper pressure pull the **** and it is disabled.

The smoke machine does work good but have found leaks with that that the smoke machine could not.

 

well you are saying 4 PSI right?

My smoke machine only puts out .5 with no pressure (when holding in the air) 2.5 PSI max when in a chamber. So yes that would make sense.

 

But that is only stubborn leaks.
